The waterproofing industry—and the construction industry as a whole— is in the middle of an unprecedented period of change. Within the last 18 months, half a dozen major factors have combined to create a “perfect storm.” Companies and contractors that do not adapt to these new conditions will be forced aside. Here’s just a few: Economy: The construction industry is in the middle of its worst slowdown ever. Residential housing starts are lower than they’ve been in 20 years, and the drop was as sudden as it was steep. (The decline from 2005 to 2008 is more than 70%.) Commercial construction, which usually lags behind residential, has slowed dramatically as credit has dried up. While conditions have stabilized, they’re not expected to improve dramatically for at least two more years. Businesses must learn to thrive in the new reality. Sustainability: Simply put, the green building movement will change the way this industry builds. From solvents to sitework and everything in between, waterproofers will need to adapt. “Green building” practices are already mandated by various agencies, and they’re rapidly being incorporated into model building codes. Legal Environment: Recent natural disasters—hurricanes on the Gulf Coast, flooding in the Midwest— have spotlighted the need for quality waterproofing. But these disasters have also created hundreds of lawsuits and new regulations. Everything from sump pump wiring to mold remediation is getting reby Clark Ricks examined. Laws affecting employee pay, benefits, safety regulations, tax rates, and insurance are also constantly changing. New Materials: Today’s cutting-edge products, like silane sealants, urethane grout compounds, and carbon-fiber repair kits make waterproofing work faster, easier, and more effective. If you don’t know about new products, chances are that your competition will— and they’ll get the job. New Technology: Sticking with “yesterday’s technology” may make your business “yesterday’s waterproofer.” A solid company website has moved from luxury to necessity. Customer databases and employee cell phones are “standard operating procedure.” I believe that great change is always accompanied by great opportunity. By staying on top of all of these issues, a waterproofing company can become even more successful than he was a few years ago. That’s where this magazine comes in. We want to help you navigate these troubled times. Let me know what more we can do to help. "Great change is always accompanied by great opportunity." 6 WATERPROOF!

News Housing Begins Recovery U.S. housing starts unexpectedly snapped the longest streak of declines in 18 years in February, rising 22% from January. The jump was influenced by warmer weather and an 82% surge in starts on condominiums, apartments and townhouses that’s unlikely to be sustained, analysts said. Building permits, a sign of future construction, at a lower rate, indicating construction may again slow. Total home construction for this year is expected to be about 450,000 homes. Developers are still contending with record foreclosures that depress prices and profits, and the glut of unsold properties on the market means the housing industry’s recession will probably continue for some time. While economists say these numbers indicate the worst of the contraction may have passed, don’t expect a rapid rebound. “We expect demand for all homes, both new and existing, to remain far below normalized levels,” says one economist. NAWSRC Plans Convention The National Association of Waterproofing and Structural Repair Contractors (NAWSRC) will hold their Annual Convention next month. It is scheduled for August 22-23, 2009 in Fort Lauderdale, Fla. The Welcome Reception will start on Sunday at 7 p.m. For those planning to take certification tests at the convention, the certification seminars will be on Sunday from 1-5 p.m. with testing Monday from 1:30-3:30 p.m. On Monday, educational seminars will start at 10 a.m. and run until noon. After lunch the non-compete round table will be in session from 1:30 to 4:30 p.m. The Educational Seminars on Tuesday will start at 9 a.m. with Round 8 WATERPROOF! Tables from 1:30 to 4:30 p.m. The Awards Dinner will be from 6 until 9 p.m. on Tuesday. The NAWSRC will announce the winners of the STAR Award and hold elections for open Board of Director positions. They will also honor those newly certified members. New members of the association receive a meeting credit that can be used to help pay for the Annual Convention. To register for the meeting or for more information about the association, visit www.nawsrc.org. Kryton Offers 10-Year Guarantee Vancouver-based Kryton International Inc. now offers a performance warranty for structures using their unique crystalline waterproofing product. The Krystol Assurance Program guarantees that areas of a structure waterproofed by Kryton will remain watertight for 10 years. It also provides enhanced quality control and project support through consistent onsite supervision, mix design consultation, jointing design review and training for applicators. “Water intrusion and the damage it causes is the number one contributor to a concrete repair industry worth billions of dollars every year,” says Kari Yuers, CEO of Kryton. “Concrete waterproofing.. is one of an owner’s most strategic investments and this program ensures that investment pays off with long term peace of mind.” The program is distinct from Kryton’s standard warranty, which guarantees that every product is free from manufacturer defects. Therma-Stor Adds Staff Therma-Stor Products, manufacturer of several lines of dehumidifiers and moisture control products, has added two senior staff members. Steve Reppen was recently hired as the National Sales Manager for UltraAire Products. Reppen previously held national sales leader and general management roles at Milgard Windows and Merrillat Industries. Bob Adamson has also been brought into the company to serve as Senior Product Manager-Residential Products. Adamson previously held leadership roles in product development, account management, marketing & engineering at firms serving industrial and transportation industries. Therma-Stor Products specializes in products that promote moisture control for the optimization of Indoor Air Quality and Asset Protection. SWRI Launches Two New Validation Programs In addition to their product validation program, the Sealant, Waterproofing & Restoration Institute (SWRI) is now validating contractors. The overall objective for both the Training Validation and Contractor Validation programs is to ensure that owners and designers receive the highest standards of workmanship. The Training Validation Program analyzes the contractor’s quality assurance program, and ensures applicators know how to properly install a given product. Specific technical content has been outlined and is required for review. In the Contractor Validation Program, the Contractor will be evaluated on similar project experience, key management personnel, financial stability, safety, training, insurance and other marketplace benchmarks. Contractors will be awarded a Recognition Level (i.e. Platinum, Gold, Silver, Bronze) as their validation seal based upon results of their application. According to Erin Neid, a marketing director at SWRI, the ultimate goal of both programs is to assist the end user in selecting competent firms to maintain their structures. Nichols comes to Bilco with more than 19 years of experience in the building products industry. “Kent Nichols’ sales, marketing and international business development skills, combined with his expertise in the export markets of the Middle East, Latin America, Canada and the Caribbean, will play a key role in our international expansion plans,” said Dominic DeConciliis, Bilco’s vice presicent of sales and marketing. Regional Waterproofing Meetings a Success The National Association of Waterproofing and Structural Repair Contractors (NAWSRC) has launched a series of regional meetings, aimed at providing the benefits of NAWSRC New Logo for AWD American Wick Drain, a leading manufacturer of sheet drain and green roof products, has a new logo. Unveiled at World of Concrete 2009, the new logo consists of a stylized letter W with a raindrop in the corner , emphasizing the company’s primary focus on stormwater and groundwater drainage. New International Sales Director at Bilco The Bilco Company, which manufactures window wells, cellar doors, and other basement products, has a new director of international sales. Kent Nichols is now International Sales and Marketing Manager. In his new role, Nichols will be actively involved in the company’s marketing efforts, strategic planning, new products and business development. Spring 2009 9 membership to waterproofing contractors across the country. They kicked off the program in Chicago on May 22-23, 2009. The two-day event had a full schedule of educational seminars covering topics from indoor air quality to internet marketing and the basement repair industry. The first day focused on how basement repair contractors could help real estate agents sell houses faster. This seminar also provided an opportunity to meet and network with local real estate agents and inspectors. The second day catered to contractors with topics such as how to become more profitable. The event’s primary sponsor was Metropolitan Industries Inc., in Romeoville, Ill. which offered a tour of its pump manufacturing plant. The 100,000 sq. ft. facility makes sump pumps and other dewatering devices. The tour also included the newly opened Energy and Water Independent Metro-Green house nearby. This 480 sq. ft. green home is equipped with solar panels, a windmill, a full rain harvesting system, solarpowered radiant heated floors, and a solar-powered well pump. The next NAWSRC Regional Meeting will be in Atlantic City, New Jersey in November 2009. For more information, or to sponsor a regional meeting of your own, visit www.nawsrc. org. New Site on Deck Coatings A new website has been launched focused on waterproof deck coatings and issues related to them. The site, www. deckexpert.com, and the related blog waterproofdeckcoatingadvice.blogspot. com contain product information, troubleshooting, and installation guidelines. Begun by Bill Leys, “The Deck Expert” in 2007, the site has been redesigned and reformatted to make information easier to find. The site has information and videos about deck construction, safety issues and retrofit advice. It also contains dozens of links and comments about how to waterproof horizontal above grade deck surfaces of any material.

Meadows International Leak Detection (ILD®) is the worldwide leader of integrity testing technology. Why do this... Historically, flood testing was utilized to confirm that waterproofing and roofing membranes were watertight. However, flood testing has many drawbacks, especially when comparing it to the latest EFVM® testing method only used by ILD®’s trained and certified technicians. EFVM® vs When this can be done! Flood Testing ILD® technicians use EFVM® testing to pinpoint exact breaches in membranes without relying on wet spots within the insulation or visual confirmation of a breach. Only proves the capability of a waterproofing membrane to HOLD water; it cannot locate breaches or verify the absence of any breaches. EFVM® requires as little as a spray of water or existing water within the overburden to test waterproofing. May actually cause more damage with membrane breaches from the required amount of flood water. EFVM®’s technology can be used on flat, sloped and vertical surfaces. Sloped or vertical surfaces cannot be flood tested. Testing can occur after all work is completed and overburden is installed. Expensive and time-consuming, often causing delays in overburden installation and roof completion. Any breach allowing even minute amounts of water will conduct electricity to complete a circuit, measurable by the ILD® technician. Pinholes and minor seam voids escape flood testing detection which could subsequently cause mold or structural decay. The contractor can repair the defects found and have them retested the same day. Water infiltration damage from flood testing often restrains retesting. EFVM®’s non-destructive method reads through all typical water-permeable overburden mediums such as soil, sand, crushed stone, pavers, asphalt, and un-reinforced concrete Garden roofs prohibit flood testing.

The 6,300 sq. ft. of photovoltaic panels will produce enough power to meet the annual electrical requirements of 10 average households. Photo Courtesy University of Buffalo R ooftop solar panels are becoming increasingly popular. Rising energy prices, combined with concerns about pollution, global warming, and sustainable building practices have made the technology more viable than ever before. “As any technology expands, price comes down,” says Patrick Howard, CEO of the Howard Company, a supplier and consultant to both the waterproofing and solar panel market. “This is especially true of photovoltaics, and now there are all the green energy incentives coming into place as well.” In San Diego, for example, solar integrated roofing systems have been installed, or installation is in progress, on 14 city schools, with more scheduled in the coming two years. Benefits The school system expects to save millions of dollars in energy costs over the next 20 years, in addition to helping the state make progress toward the goal of generating 20% of its electricity facility to install solar panels and sell the electricity back to the users. Photovoltaic roofs also help buildings qualify for certification with green building programs. Under the U.S. Green Building Council’s current LEED criteria, a building can gain up to 3 points by using solar energy. Most solar roofs, especially in the commercial sector, are more properly called “photovoltaic panels.” These systems convert light into electrical energy using thin wafers of silicon. (The other type of panel is basically a solar hot water heater.) For rooftop waterproofers, rooftop panels create additional challenges, as the mechanical attachments, cables, pipes, and other penetrations need special “As any technology expands, price comes down” 12 WATERPROOF! with renewable sources by 2017. Howard cites cases where Southern California Edison has approached large building owners to essentially rent their roofs. In one instance, they leased back roof space on a 100,000 sq. ft. Montana attention. Recently though, several new technologies promise to radically simplify installation, and make solar energy generation more cost-effective than ever before. Built-In Panels Photos Courtesy Brian Blaquiere/Sika Sarnafil Frito-Lay, the snack food maker, installed a photovoltaic roof on its 65,000 sq. ft. facility near Los Angeles, California. The Frito-Lay Distribution Facility in Los Angeles uses a new technology that combines a waterproofing membrane and solar panels into a single flexible product. The decision was partially driven by the chronic power outages that plagued the state in 2000 and early 2001. Electrical blackouts and record high energy bills made business difficult. The company also has a reputation for being environmentally conscious. So when the distribution warehouse needed to replace the existing built-up roof with a durable, long-lasting alternative, they chose to include solar panels. “The LADWP [Los Angeles Department of Water and Power] was offering a substantial incentive to install solar photovoltaic roof systems,” says Chris McKenna, electricity manager at Frito-Lay. “That made the project economical for us.” The project was the first to use a new product from Solar Integrated Technologies (SIT) called SR-2001. The design combines an impermeable waterproofing membrane with photovoltaic cells in a single sheet. SR-2001 uses a 60-mil single-ply thermoplastic membrane from Sarnafil as a base, then laminates a dozen flexible, thin, lightweight photovoltaic modules onto it. Peter Chaitkin, account executive at Solar Integrated Technologies, says they chose the membrane due to its performance history and heat-welded seams. “It provides the owner with a durable roof that lasts for decades,” he says. The 10-ft-by-40-ft photovoltaic roofing panels are then hot-air welded to an installed Sika Sarnafil EnergySmart Roof. Each panel generates approximately 1,500 watts. The result is a photovoltaic roofing system that protects the building interior from the elements while generating power for its electricity needs. Southern California Roofing got the nod to install the system. First, we arranged the photovoltaic modules according to the customer’s request for kilowatt power,” said Chuck Point, project manager at Southern California Roofing. Since Frito-Lay wanted a 100 kilowatt system (100,000 watts), the roof needed 70 of the 10x 40 panels. He says the actual installation went smoothly, noting that the company has installed Sarnafil products for more than 20 years and the workers are very familiar with it. The outer face of the membrane is white, which increases the panels’ efficiency. “The membrane’s reflectivity allows the flexible photovoltaic panels to absorb more of the sun’s rays in less-thanoptimum conditions,” said Chaitkin. “The EnergySmart Roof membrane reflects the sun’s rays, reduces heat absorption into the building, decreases cooling costs, and actually increases the productivity of the solar panels.” Energy from the panels is collected in wires and routed to inverters that convert the DC power into alternating current that Frito-Lay can use to run computers, lights, air conditioners and other equipment. Completed in 2003, the roof Conventional solar panels are rigid, and sit above the roofing membrane. The penetrations, supports, and flashings these require need special attention to ensure the roof remains impermeable. Spring 2009 13 generates about 186,000 kilowatt hours of clean energy annually, enough electricity to power 28 homes. “The system works so well that during some periods of the day, we are producing more power than we need,” said McKenna. “When that happens, the extra power gets fed back into the utility grid.” The company has since installed another system on its Sylmar, California distribution center roof, and anticipates additional installations in the future. “The Most Exciting Project I’ve Worked On” Photos Courtesy Brian Blaquiere/Sika Sarnafil The same SR-2001 panel was also used on the National Archives and Records Administration (NARA) building in Waltham, MA. The facility stores thousands of irreplaceable federal documents, so when its EPDM roof started failing, it was critical to find a new roof. “We had considered different types of roofing systems, including TPO, PVC and EPDM, but we wanted an Energy Star ‘cool roof ’,” says Roman Piaskoski, regional energy coordinator for the government agency overseeing the project. “When we heard of this system that uses flat thin film, flexible, amorphous silicon panels integrated with a Sarnafil EnergySmart Roof we thought ‘Hey, this could be it!’” In addition to saving the GSA about $67,000 per year in electrical costs, the built-in photovoltaic (BIPV) system will 14 WATERPROOF! Built-in photovoltaic (BIPV) roofing is becoming quite common—and lucrative. The roof of the National Archives Building in Maryland (above) is literally covered with BIPV panels. They were attached to the existing membrane using hot-air welding (below). On sunny days, excess energy is sold back into the power grid. also result in substantial greenhouse gas reductions. “This is one of the most exciting projects I’ve worked on in my 17 years with GSA,” Piaskoski stated. Metal Roofing Options Built-in photovaltaics are becoming quite common, and are available for many different roofing systems, including metal roofing. SolarPower Restoration Systems markets SolarSeal PV, a metal roof system that combines photovoltaic technology with high-performance elastomeric coatings. According to Michael Gunn, company vice-president, it creates a leak-proof, energy-generating roof over any standing seam or R-panel industrial metal roofs. “Commercial buildings with metal roofs use industrial R-panel roof panels or the newer architectural standingseam roof panels,” he says. “Both R-type roof panels and the architectural snap seam metal panels are waterproofed using elastomeric coatings designed to work with each specific type of metal roof surface.” Once the roofs are waterproofed, solar modules are applied to the coated metal surface. Materials such as synthetic textiles, polymers, insulation or radiant water modules are used to bridge irregular metal panel surfaces and exposed fasteners. Photovoltaic modules are bonded to the components and flashed and sealed, creating a continuous, seamless, waterproofed roof surface. “The SolarSeal Roof System is a long-term solar waterproofing solution for metal roofs,” says Gunn. “They’re easy to maintain and can be renewed without affecting the photovoltaic system’s power production.” He adds that, like SR-2001, the white elastomeric coating reduces metal roof surface temperatures and lowers cooling cost. SYSTEMS W hether used as a drainage board, underslab insulation, or in roofing systems, every waterproofer deals with foam board. “Rigid foam insulation works very well with many waterproofing systems,” explains John Cambruzzi at Insulfoam. “It’s a product that is well established and well known from a performance standpoint.” In recent years, some have said that rigid Expanded Polystyrene (EPS) foam was obsolete for below-grade 16 WATERPROOF! applications, but Cambruzzi disagrees. “It has a long history of excellent performance in both horizontal and vertical belowgrade applications,” he says. The key is understanding the material, its strengths and limitations, and ensuring that the waterproofing design takes these traits into consideration. Vertical Below-Grade One of the most common construction applications for Photos Courtesy John Cambruzzi/Sarnafil F OA M I N WATERPROOFING EPS is use as a protection course or drainage layer on vertical below-grade work. Dimple drain sheets, fiber mats, or inorganic mineral wool are sometimes used instead, but Cambruzzi says EPS has real merit. “From a rigid foam standpoint, the advantage, with our product, is the insulation value you’re getting,” he says. “If you’re planning to insulate because you have working or living space on the inside, EPS gives you an advantage that no other product can.” Dave Nichols, vice-president of marketing at Mar-Flex, says rigid foam drain boards are popular for another reason as well. He states, “Contractors use foam because it’s lightweight and easy to install.” It’s true that other materials require much more labor. Foam boards are simply pressed against the newly waterproofed wall, where the tackiness of the spray-applied membrane holds it solidly in place until the wall is backfilled. Drain sheets, on the other hand, require mechanical fasteners, transition strips, and other components. While Mar-Flex does sell rigid foam boards, Nichols insists there are better options on the market. “I’d rather have it than nothing, but there are better choices in the waterproofing world,” he says, although he admits, “A lot of times it’s the best answer for a foundation.” His major objections are that the grooves in the drain board fill in, and that foam compresses under the weight of the backfill. Cambruzzi says current foam boards on the market have resolved those concerns. Spring 2009 17 "The biggest risk installers face is that foam sheets will break and chip before the concrete slab is placed over them." “Our product has a filter fabric on it that covers the channels,” he says. “That keeps the sediment out of it. From a long-term performance standpoint, we don’t have a problem with those channels filling up with sediment.” He also disagrees with claims that compression from backfill pressure leads to a loss of R-Value. “Ground pressure has a minimal impact on R-Value, and is not a big concern in terms of long-term performance,” says Cambruzzi. “Our experience indicates that the product compresses very little.” He adds that Insulfoam can manipulate the density of the foam from as low as 10 psi to as high as 60 psi. “If the specifier knows the load, we can take expense out or add it in to meet job conditions.” Both agree that a waterproof coating behind the drainage layer is crucial. “The most important thing is protecting it from moisture penetration,” says Nichols. “You need a good coating 18 WATERPROOF! on the wall before you get a protection layer on that.” Horizontal Below Grade Another common area where waterproofers have to deal with foam is when they are used in underslab applications. Like vertical above-grade work, a membrane is used to eliminate moisture coming through the slab, while the foam keeps the concrete warm. This type of work is especially common with in-floor hydronic heat or any time the slab itself has heating or cooling elements within it. Installation guidelines vary on whether the foam should be installed on top of the moisture barrier, or beneath it (see The Underslab Solution in the Winter 2009 issue for more information), but the challenges are the same. The biggest risk installers face is that foam sheets, often only an inch thick, will break and chip before the concrete slab is placed over them. Sheets that are thick enough to avoid breakage cost more, and provide negligible additional energy savings. Luckily, there are good solutions on the market. The most important step, regardless of the product installed, is to ensure the subgrade is flat, level, and properly prepared. Cambruzzi, at Insulfoam, says manufacturers can manipulate the compressive strength of the foam to create a more flexible product. “The higher the compressive strength of the foam, the more rigid the product is, and the more susceptible it is to breaking,” he states. “By taking some of the density out of the product you’ll get a foam that’s more jobsite friendly.” He notes that even a 25 psi foam provides resistance of 3,600 pounds per sq. ft., plenty of resistance for most underslab applications. His company also offers foam with a polymeric film on both sides, which helps to keep the EPS from chipping and shattering. If it does break, the film holds the pieces together so the effect is negligible. “In a below slab-application, an unfaced or unskinned product performs fine. But the film makes it more jobsite durable, more moisture resistant, and less likely to be damaged during handling and installation. The plastic film on Insulfoam sheets does not serve as waterproofing however. MOISTURE HAS MET ITS MATCH. Valéron® Strength Film makes your product better. Better moisture resistance.

Northwestern Ohio Foam Products markets the Barrier and BarrierXT, both of which provide a flexible insulated underslab barrier. The rolls are 60 feet long, so instead of having gaps every 4 and 8 feet, there are just a few seams. The product has a self-taping flange on one edge that makes these easy to seal. “The biggest thing is installation cost,” says Wally Radjenovic, president of NOFP. “Normally, the insulation and the vapor barrier are discrete components, and it’s very time consuming if you have to lay and tape two products. You’re adding a lot of labor dollars to an already expensive product. By combining them into a single product like the Barrier, it’s easier to meet deadline, and you’re saving money, too.” Of course, another advantage of a flexible core is that the installer doesn’t have to be as exacting when installing the subbase, which saves on labor costs as well. The flexible EPS foam in the standard Barrier is 3/8 inch thick. The BarrierXT has ¾ inch. The moisture barrier is 3 mils thick on both products. Roofing A third area where waterproofers often have to deal with foam board is commercial roofing. Like underslab insulation, the placement of the foam varies from job to job. On some roofs, the foam is installed over the membrane; in other applications, it is placed below it. The major challenge in this area is that roofing membranes often require heat and/or harsh solvents, both of which are incompatible with foam. “Foam plastic do not do well in the presence of solventbased adhesives,” says Cambruzzi. “In applications where these solvents will come in contact with these products, the installer or specifier needs to use a different insulation or have a plan how to avoid contact, like using a slipsheet. Foam’s sensitivity 20 WATERPROOF! to solvents is a drawback. It’s something that you would have to recognize and address.” Solvents are not only bad for foam, but they’re bad for the environment and the installer’s health. Because of this, many roofing suppliers are moving to more environmentally friendly products; singly ply membranes, adhesive tapes, and heat welded seams. So solvents are becoming less of an issue. Long Term Performance Another common concern is moisture resistance. While foam is not as moisture resistant as, say, a dimple drain sheet, it does outperform other insulation options, like rock wool or open-cell foam. Cambruzzi points out that although EPS foam will absorb some moisture from saturated soils, it readily gives up that moisture when surroundings dry out. “Over a seasonal or annual cycle, that foam will continue to perform, because it readily gives up that moisture,” he states. With the rising interest in green building, the sustainability of expanded polystyrene is also a topic of interest. EPS is a petroleum-derived product, and requires a significant amount of energy to make and transport. But according to a recent study published by the EPS Manufacturers’ Association (EPSMA), the insulating value of the foam saves more than 100 times more energy than was used in its manufacture. “EPS is environmentally friendly, 100% recyclable, containing no HCFCs or formaldehyde and can contribute toward LEED credit requirements,” the report states. Some competing products have done a good job convincing specifiers that EPS is not a good option,” says Cambruzzi, “but EPS has a long history of excellent performance in both horizontal and vertical below-grade applications. EPS has been used in geofoam applications, going under exit ramps, highways, and bridge approaches, and has performed just fine in those harsh conditions.” “When used with standard waterproofing products, there are no real compatibility issues,” he continues. “They’re operating and functioning independent of each other.” R-Tech ® High Performance EPS Insulfoam, the leader in block-molded EPS offers R-Tech - an amazingly versatile, durable and lightweight insulation that is 100% recyclable.

Advances and Installation I t’s a nightmare every homeowner dreads: The basement flooded, belongings soaked. Carpeting and drywall ruined and waterlogged. While a comprehensive waterproofing and drainage system has many components, sump pumps are considered the most crucial. Unlike the membranes, drainage sheets, and perforated pipe, which usually last for the life of the structure, sump pumps need to be replaced every few years. But waiting for failure isn’t an option, as it would inevitably lead to the nightmare described above. Fortunately, new pump technologies and proper installation can ensure that this critical piece of the system is fail-safe and affordable. Components All sump pump systems have the same five components, although they vary in size based on the amount of water they are required to handle. In the United States, components are fairly standardized. For residential applications, they consist of: 1. A plastic or metal sump liner, either 18 or 24 inches in diameter and 2 to 3 feet deep. 2. A pump, usually 1/3 or 1/2 horsepower and powered by either at 12-volt DC battery or standard 120-volt AC current. 3. A discharge pipe, typically 1 ½ inch PVC. 4. A check valve to ensure the water in the discharge pipe doesn’t flow backwards back into the sump; 5. A cover to keep vermin, pets, and debris out of the sump. Sizing Pump Size: A properly sized pump is critical. Too small and it won’t be able to keep up with water flowing into the sump. Too large and it creates unnecessary expense. An oversized pump will also “short-cycle,” turning on and off in rapid succession, which leads to premature pump failure. So getting the right pump is an important first step to ensuring basements stay dry. “It’s important that your pump can draw water out of the basin (or “sump Photo Courtesy Pedigo Construction Photo Courtesy Champion Pump 2 also increases the chances the sump will overflow, so be careful. Power Supply Direct-Wired: Almost all sump pumps run on standard 120 volt AC current, but the pump must be supplied with its own line from the breaker box. It must also have a dedicated breaker. In most areas, the power supply must be installed by a licensed electrician unless the installer is also the homeowner. As always, check with local building codes and ordinances. Pumps are usually hard wired into the electrical system, rather than plugged into a conventional outlet. Battery-Powered: Sump pumps face their highest loads during The SmartHome sump pump (above) is a next-generation batteryoperated sump pump. It is selftesting, self-diagnosing, and will immediate notify the homeowner by telephone and email if a component stops functioning. thunderstorms, when rainwater pours into the sump pit from the foundation drainage system. Unfortunately, thunderstorms can also disrupt a home’s power supply, knocking the pump offline at the time it is needed most. That’s why "New pump technologies and proper installation are a critical piece of the system" cheaper option may be to raise the height of the pump switch, basically making the sump deeper. This method, however, Decking & Waterproofing Solutions Engineered for Sustainable Protection — Protect your investment — Maximize property space Photo Courtesy PeakFlow Pumps pit”) faster than water flows into it,” notes Duane Friend, at the University of Illinois Extension Office. “Therefore, the first thing you need to measure is the amount of water that drains into the basin during a high-flow period. During a heavy rain, stick a ruler in the basin and measure how many inches of water flow into the basin in 60 seconds.” With an 18-inch sump, each inch of depth equals one gallon. In a 24-inchdiameter basin, each inch is roughly 2 gallons. In a new construction situation, approximate flow rates can be calculated based on rainfall averages, soil type and the size of a home’s footprint. Once the volume of water that will need to be removed has been calculated, the installer will need to figure out the “total dynamic head” of the discharge pipe. This is the sum of the “static head” (the height in feet between the pump and the end of the discharge pipe) and the “friction head.” Friction head is calculated based on the length, diameter and material of the discharge pipe, and the number of turns involved. A table to calculate friction head is available on the www.waterproofmag.com website. Knowing the maximum flow rate figures, the total dynamic head pressure involved, and the budget, the contractor or designer can determine the best pump for the application. Basin Size: The size of the sump pit is also important, as it plays a part in how long the pump runs and how long it takes to fill up. If the basin fills too quickly it may be best to install a larger one.

In a few areas of the country, where the sump pit only fills occasionally, battery-operated pumps are used as the primary. Setting up a battery-powered secondary pump involves purchasing and installing the following components in parallel with the others: • A 12-volt DC sump pump matching the flow and discharge requirements of the primary pump. • A 12-volt DC lead-acid battery. A typical automobile battery is adequate. Some use marine-grade deep cycle batteries which are more expensive, but lasts longer. • A “trickle-charge” battery charger to keep the lead acid battery fully charged. • A separate water level sensor, check valve, and other components. The discharge pipes usually connect downstream of the check valves. “One of the problems with most backup sump systems is they are rarely used so a component failure will not be noticed and the system will fail to operate when needed,” says Friend. A few battery-powered pump systems have an integral computer that tests the system periodically and sounds an alarm if something needs to be replaced—like a “check engine” light 24 WATERPROOF! on a car. Regardless, Friend recommends that backup systems be tested monthly. “A good time to test is just after a rain storm,” he says. “Pull the plug on the sump pump so the sump well fills and verify the backup system activates and empties the well.” Water-Driven: Recently, a few manufacturers have begun offering sump pumps that use the home’s culinary water supply to power the pump. The pressure in the home’s main water line turns an impellor, which drives the pump. These devices eliminate the need for electricity entirely. They do cost more than motordriven pumps, but because they don’t need a back-up pump, they can be costeffective. Regardless of the type of pump installed, plan on also using a simple battery-powered water alarm. The water sensor is attached to the sump liner a few inches below floor level and will sound a shrill alarm if the water level rises that high. Pump Type Regardless of the type of power supply, sump pumps are generally divided into two classifications, pedestal and submersible. Pedestal pumps are mounted above Discharge Pipe The discharge pipe should end as far from the house as possible, to prevent the water from finding it’s way back under the foundation. In decades past, the pipe was often connected to the sanitary sewer system. This practice is now outlawed as it can overwhelm the water treatment facilities. Be aware that if you are retrofitting an older home, codes and ordinances may require you to also reroute the discharge line. Photo Courtesy Nu Image Home Improvement Photo Courtesy Pedigo Construction The discharge pipe (black pipe on right) should end as far from the house as possible. Here, it has been routed to a dry well, with perforated pipe and gravel to improve drainage. the pit, where it is more easily serviced, but also more conspicuous. Submersible pumps sit inside the sump—usually near the bottom—and are completely immersed in the water. The decision is usually based on whether the basement is finished, or will be, as the submersible pump is less obtrusive. In commercial applications, submersible pumps are most common, as they funtion on a different principle. Unlike pedestal pumps that “suck” water up from the sump like soda thorugh a straw, submersible pumps “push” water up the pipe. Because pedestal pumps sit above floor level, they are usually hidden from sight in finished basements. This can be a purpose-built enclosure, as shown in the before-and-after photos above, or by building the sump in a closet or furnace room. Green Sealants at the Bottom of the World by Clark Ricks P rincess Elisabeth Station is not a typical construction project. Built by a Belgian team to study the harsh Antarctic environment, it was built in one of the harshest and most remote regions of the planet. It was also built with extremely demanding green building techniques. When construction ended in February, it became the only zero-emissions building on the continent—the first to operate without releasing any greenhouse gases. The 20 million euro ($26 million) science station is completely energy self-sufficient, and uses micro-organisms to re-use water up to five times. Power and hot water are made possible by wind turbines on a nearby mountain and solar panels mounted on the building. The Antarctic research station is located in Dronning Maud Land, thousands of miles south of the African coast. Finding a long-lasting sealant that would perform in one of the planet’s harshest climates, while still meeting the zeroemissions green building standard was one significant challenge designers faced. Scientists at Dow Corning said silicone sealants were up to the challenge. Jean-Paul Hautekeer, European construction director for Dow Corning explains, “Dow Corning silicones are virtually unaffected by weather—rain, snow, humidity, ozone, temperature variation or the sun’s damaging ultraviolet rays—and can make building what we may think is impossible, possible.” 26 WATERPROOF! The silicone sealant used at Princess Elisabeth research station has a proven record in extreme environments. It’s similar to the product used in the silicone rubber boots astronauts wore when they walked on the moon’s surface, where temperatures drop to -150°C. The final phase of the station’s construction lasted a little over 4 months, and research teams will begin living there as soon as November 2009 to conduct climate change research. Engineer’s Corner Tips for Protecting Building Aesthetics By Larry Carbary Because the physical condition of a building can change greatly over time from such external forces as sun, wind and rain, choosing materials that will maximize the life and appearance of the structure, while minimizing the amount of damage is crucial. This is especially true in selecting a sealant. Here are some of the most common aesthetic issues to consider: Dirt Pick-Up – Accumulation of dirt on a sealant’s surface is particularly prevalent on construction sites with high volumes of dust. The actual amount of dirt pick-up will vary with exposure conditions, but excessive pollutant contamination will result in lower durability and weaker bond strength. To avoid this, choose a sealant that can tolerate higher levels of contamination. Chalking – As the substrate begins to degrade and erode over time, the surface becomes more rough and porous, which leads to a loss of surface gloss and color. Chalking is most observed in organic sealants that are initially black or brown, but later transform into a light grey or beige. This does not occur with silicone or acrylic sealants. Change of Color – Change in color can result from factors both inherent and external to the sealant. Incompatibility of the sealant with other building materials is a contributing factor. Materials with high incompatibility levels include low molecular weight polymers, antioxidants, or tar. A sealant that is compatible with a variety of other substrates is preferable. Surface Crazing – A variety of factors including sunlight, environmental stress and ageing can cause cracks in the sealant’s surface. This is especially common with organic sealants. Generally, sealants with higher polymer content are more durable and have less crazing. Fluid Migration – Fluids can migrate from a sealant to the substrate, creating a dark “wet” band look around the joint of the sealant. The extent and rate of fluid migration varies with the type of sealant. Cheaper, less formulated sealants are the most prone to staining and fluid migration. Other Environmental Factors – Oxygen, ultraviolet radiation, climate/temperature, microbial growth and other environmentally-induced mechanisms can contribute to the fatigue and stress that degrades and lowers the overall bond strength of the sealant. While aesthetic issues cannot be completely avoided, they can be mitigated through prior knowledge; selection of high-quality, highperformance building materials; and working with a reputable manufacturer.

Both are specifically made to seal rock, stone, concrete, and similar materials. The 6706W and 6707W Penetrating Stain Repellents are water-based fluorosilane post-treatments that provide effective, environmentally-sound water and oil repellency. According to Shawn Kuch of Dow Corning’s building materials protection group, substrates treated with the products remain permeable to water vapor and retain their original appearance with the additional benefits of reduced dirt pick-up and easier cleaning. “Environmental factors such as water, oil, stains, and sunlight can have harmful effects on construction materials by damaging surfaces, reducing aesthetic value, and increasing maintenance costs,” said Kuch. “Dow Corning’s new family of penetrating stain repellents provides durable, environmentally sensitive protection to these materials without affecting their appearance.” The reason the products work so well on porous construction materials like concrete, natural stone (such as sandstone and limestone), pavers, mortar, and grout is due to the small molecular size of the flourosilane, which allows it to penetrate deeply and chemically bond to the substrates. It creates a layer of protection that reduces water absorption and the damage caused by freeze-thaw cycles. The 6706W Penetrating Stain Repellent is a ready-to-use product. The 6707W product is a concentrate that can be diluted with water. Both products are solvent-free and will not damage glass, metal, wood, or most plastics.
