New technologies
to out perform concrete
RenovAction is Myrtha Pools’ patented and exclusive technology, specifically
developed for swimming pool refurbishment and renovation of existing pools.
The process is based on Myrtha Technology’s, pre-engineered, modular system which
incorporates the use of precision-engineered laminated stainless steel panels and a buttress system.
RenovAction solves all of the problems that often arise in concrete, gunite, or shotcrete
pools that have been in operation for an extended periods of time.
Why renovate?
1. Many existing pools fail to meet today’s health code regulations and therefore require
both adjustments and corrections necessary for compliance.
2. Refurbishment in order to meet new design and engineering criteria: old pools can be
upgraded, with numerous leisure components added including freeform sections, lazy
rivers, water play equipment and hydro-massage areas.
3. Outdated filtration equipment and older technology need to be changed from a skimmer system to an overflow gutter technology.
4. Traditional, reinforced concrete, gunite and shotcrete pools, will eventually develop
structural problems that require significant maintenance and intervention, resulting in a
substantial investment.

The materials
RenovAction uses superior materials that Myrtha Pools specifically designed for swimming pool use.
Stainless steel
PVC
Finishes
High-quality stainless steel guarantees extremely long
life to the structure. RenovAction uses exclusive modular
components, eliminating welding of the panels, which
are subject to increased levels of corrosion.
Stainless steel ensures maximum mechanical strength
of the individual panels resulting in the structural integrity
of the entire pool.
Perfect waterproofing is ensured by the unique process
of bonding PVC to the Myrtha steel panels.
A hard PVC membrane is hot-laminated to the steel in
the manufacturing process and a reinforced membrane
is used on the concrete sub-surface floor of the pool in
order to ensure waterproofing.
To achieve high-level finishes, RenovAction uses
ceramic and special vitreous mosaics, as well as
outstanding stones and marbles, that compliment the
range of PVC colors.
Unlike traditional concrete installations, RenovAction
exclusively uses ceramic tiles to cover the upper part
of the pool panels. The superior quality of the adhesive
materials utilized considerably limits the occurrence of
traditional problems such as the detaching of the tiles.

Why RenovAction?
Company
experience and
knowledge
Minimum
interventions,
zero demolitions
50 years of experience, 1,500 pools
per year, including 300 for public
use; more than 50 installations for
international swimming events and
references in over 60 countries; a
highly-advanced technical department
with direct transmission of the
drawings to production; a research
& development team for laboratory
testing; and installation groups factory trained during professional seminars by
Pool Academy.
RenovAction does not require
destructive demolition of the existing
structure, thereby resulting in
considerable savings with regard to
both the installation time and overall
costs.
The internal surface of the original
pool remains unchanged, only the
accessories on the walls or on the
floor are replaced.
Renovation
quickness
Fixed costs
The renovation of a concrete pool
requires an extended time for the
preparation, curing of adhesives,
and drying time for plaster and
waterproofing materials.
RenovAction allows rapid installation
stages, without lengthy pool
preparation times or the use of
specialized building equipment. This
avoids the protracted closing of the
pool.
RenovAction reduces both
refurbishment and routine operating
costs of the pool - higher costs
typically required to maintain the
pool finish and ongoing maintenance
required by traditional pools.
Shorter installation time significantly
reduces the risk associated with cost
overruns.

Long life,
extensive
guarantee
Suitable for
difficult field
conditions
RenovAction pools offer a virtually
unlimited lifespan, thanks to the
structural integrity of materials, and
to advanced technological features
of a modular system. This is why
RenovAction can confidently warrant
it’s pools for many years.
Seismic activities, unstable and
expansive soil conditions, or
dramatic temperature swings will
damage traditional concrete pools.
RenovAction design and seismic
engineering is flexible and therefore
the ideal system for pools built in
such conditions. In specialized and
challenging environments, such
as elevated floors of buildings, or
in limited spaces, there is minimal
change required to accomodate the
pool dimensions, thanks to the ability
to adjust the distances.
Low and easy
maintenance
Environmental
respect
Unlike traditional construction,
RenovAction pools do not require a
significant maintenance schedule.
The RenovAction structure is sturdy
and not subject to dimensional
variation. It will not experience
cracking, or leakage, and is not
affected by the aggressive hyrdrualic
action of chlorinated pool water.
Whit most Governments
recommending the reduction of
CO2 emissions, Myrtha Pools
commissioned ACOR Consultant
to calculate the energy used in
building a Myrtha pool. The Carbon
footprint of Myrtha (the quantity of
CO2) is significantly lower by 50%
compared to a traditional pool made
with concrete and tiles: Myrtha could
provide heat to a 100sqm apartment
for at least 45 years!

The installation process
The RenovAction installation process is both simple and fast, without the possibility of
mistakes or delays in the renovation work.

Rails installation
Spacers installation
Panels installation
The existing surface of the pool is
normally left untouched. Stainless stees
rails are aligned and fixed to the pool
wall before panel installation.
High density spacers are installed
between each rail to avoid panel
bending.
Wall panels are inserted on the
previously-aligned rails. The installation
of a RenovAction pool always starts from
the corners. To cover the corners of the
walls a special corner piece is used.
The spacers allow the precision of the
installation. Glued between the concrete wall
and the panel, once fixed, they are trimmed
off thanks to the use of a high temperature
electric cable.
Overflow gutter
installation
Installation of the overflow gutter on steel
supports anchored to the concrete.
The gutter is manufactured with Myrtha
stainless steel and it can be installed at
adjustable height and with sloping angle.

Waterproofing of the
structure: panels
sealing
Waterproofing of
the structure: joints
protection
Floor covering with
reinforced PVC
membrane
Once installed, the entire structure is
waterproofed with a combination of PVC
semi-rigid sections and a special Myrtha
sealant applied on the joints of the wall
panels, guaranteeing a perfect weld on
the entire surface.
A reinforced PVC tape is welded on
the gutter joints to ensure maximum
waterproofing.
The floor is lined with a special reinforced
PVC membrane, applied in rolls by hot
welding them together. Wall panels and
the floor are joimed together by a PVC
profile, which is then hot-welded both to
the wall and the floor.

Finishing installation
Ceramic tiles are applied onto the
Myrtha surface. Gluing tile on a Myrtha
stainless steel surface is much easier
and safer that on concrete, as there is
no possibility of water penetration from
beneath the tiled surface.

Individual solutions
for every installation challenge
Case A
Case B
The circulation systems
As per project requirements, the new
gutter section can be positioned
by partial removal of the existing
concrete gutter creating a recess
for the placement and fixing of the
Myrtha gutter. This solution does not
accomodate changes in the levels of the
surrounding floor/pool deck.
Alternatively, the gutter can be
positioned directly onto pool deck,
without any demolition of the preexisting structure. In this case the
surrounding floor level needs to be
adjusted to the new overflow level, by
placing a step section in place behind
the new RenovAction gutter.
The resultant increase in pool depth,
allows for a comprehensive renovation
of the water circulation system, as there
is enough space to install pipes and
fittings necessary for return floor inlets,
thus avoiding having to excavate to
access the old pipes.
All new pipes are embedded in a 20 cm bed of gravel, covered by a light layer of concrete,
and lined with the floor PVC, to guarantee it’s water-tight integrity. This allows remarkable
improvement of water distribution in the pool.
A considerable departure from an obsolete recirculation systems to the distribution from the floor
with an insufficient number of inlet fittings.
10 | RenovAction
RenovAction.indd 10
31/01/13 12.07
Regulator
In some cases, when it is not possible
to substitute the existing concrete
gutter, RenovAction gives the
opportunity to use a special adjustable
steel profile – called “Regulator” - that is
anchored to the concrete wall and that
allows to adjust the new overflow level.
A reinforced membrane is then welded
on this profile and connected to the old
gutter, to guarantee waterproofing of
the surface. This special solution is cost
effective although the scope of work is
not as comprehensive as in a normal
RenovAction.
Portholes and
windowed walls
Staircases and
recessed steps
In competition pools originally equipped
with portholes or windowed walls,
RenovAction technology offers the
possibility to maintain the same
accessories in the new project.
RenovAction panels are positioned
in the original openings in the
wall. Portholes or windows for the
underwater photography or video are
installed on the panels with a special
flange system.
RenovAction guarantees maximum
flexibility in planning requirements for
recessed staircases and built-in steps.
RenovAction recessed ladders are
constructed inside a panel, installed
exactly like the others, with minimum
allowance for the projection of the steps
towards the internal wall.
SoftWalk mattress
The special Softwalk surface consists of a
soft closed-cell foam mattress, positioned
on the bottom of the pool, underneath
the PVC covering. It does not deform and
maintains it’s elasticity over the years.
Combined with the non-slip bottom
covering, it is the ideal solution for obtaining
greater safety in the pool.
SoftWalk is ideal for multi-purpose pools
that include activity for shallow water pools,
modular pool toys and/or with beach entry.

Variations
and finishes
The RenovAction technology has been developed with the
aim to provide the same range of design solutions and finishes that it is possible to have with the Myrtha Technology.
Most of the solutions can be applied both on rectangular
shapes and on freeform pools.
Skimmer
The traditional Skimmer
version, which presents the
water level lower than the floor
level, has a ceramic finishing
that enriches the visible part
of the pool and helps cleaning
operations. This system is
ideal for public pools with
reduced dimensions.
Overflow Gutter
Classic
Myrtha Classic Overflow is ideal
for all the pools that guarantee
an excellent water recycle with
reduced dimensions and still
maintain an aesthetically uniform
mirroring surface. It is completed
with a simple but pleasant PVC
finishing on the highest part of
the panel.
12 | RenovAction
RenovAction.indd 12
31/01/13 12.07
Overflow Gutter
Classic Competition
The Classic structure is ideal
for big competition pools, either
on all the perimeter of the pool
or only on the two short sides.
This technology is also the
most suitable for the renovation
of pools that need to meet
international regulations.
Overflow Gutter
Ceramic / 1
For public pools usually used
for training sessions – schools,
fitness centres and sports
centres in general – Myrtha
Ceramic1 is the most used and
appreciated technology. Its
ceramic tile places the overflow
gutter slightly moved from
the boarder so that the wave
produced by the swimmer is
better absorbed and does not
reduce the swimmer’s pace.
Overflow Gutter
Ceramic / 2
Myrtha Ceramic 2 presents
two ceramic tiles that move
even further the overflow gutter
and guarantee the maximum
absorbing coefficient of the
wave impact during training
lessons or competition events:
the most suitable technology for
completion implants.

Vanishing Edge
Ceramic / 1
Overflow Gutter
Structural
Myrtha Structural Overflow
Technology is characterized by a
special Klinker ceramic tile that
functions as part of the actual
structure of the wall panels. This
structure guarantees a perfect
overflow level while maintaining
an attractive finish, in fact it
can be considered the ideal
technology for public leisure
pools with any design.
Ceramic/1 structure can also
have a vanishing edge effect
that guarantees the best
success on hills or particular
surroundings. Generally it is
utilized on one side of the pool
with a ceramic tile that follows
the external side of the pool and
ends directly in the overflow
gutter. This technology can
be an elegant and efficient
solution for public leisure pools,
especially in condominiums or
accommodation facilities.
Recessed overflow
gutter
The brand new overflow gutter finishing solution
as an alternative to the standard ABS grid.
Special edge elements, specifically designed for
swimming pools use, can be placed and fixed to
the overflow gutter, perfectly allowing the water
flow and providing a smart finishing to the pool.
Different materials and surfaces, highly durable
and with high tech performance, can be chosen
for both the deck and the edge of the pool:
marbels, stones, wood and porcelain stonewares,
inspired from natural and precious materials.

Vanishing Edge
Structural
The Overflow Structural
technology has evolved from
the Ceramic1 Vanishing edge
technology. Above the Myrtha
panels a ceramic tiles functions
as part of the structure while still
creating a gentle slop that fades
away in the gutter.
Headwalls
To comply with F.I.N.A.
regulations for competition pools
that do not have an overflow
structure on all four sides a
headwall is required at 30cm
above the water level, often
completed by ceramic tiles that
guarantee simple cleaning and
satisfies the eye.
Combined
Technologies
All the technologies described above can
be combined to meet design requirements:
competition pools combine overflow
technologies with headwalls; public and leisure
pools combine skimmer systems with one
or more vanishing edge or headwall system
too. Myrtha Pools can offer the work of a
specialized technical staff who continuously
search for the best solutions to advise the
client according to need and surrounding.

CASE HISTORIES
YingTung Natatorium at the Beijing Olympic was a major subject of focus for the Olympic competition venue renovation projects. The natatorium revealed signs of aging due
to its continuous use since being built nearly 20 years before: cracks and leakage had
become a severe problem that meant the facilities were far short of competition standards.
Completely replacing the pool would have been both costly and time-consuming. The
renovation of the pool with RenovAction involved minimal impact to the existing structure, with a marked saving in time and resources.

As determined from the results of a comparative study
performed on the pools of the Challenge, it was determined
that, in fact, the maintenance of a concrete pool is more
complex and onerous when compared to that of a Myrtha
pool. The Myrtha pool, built in1996 has not undergone any
maintenance until 2003. Conversely, the indoor concrete,
tiled 50m pools, after only 9 years of operation, have
required the total replacement of the ceramic tiles along with
major water-proofing repairs. Renovation works of the pools
started in September 2007 and each pool took only few
weeks start to finish.

The 50 m outdoor reinforced concrete tiled pool of the Center has been completely
renovated in 2007 using RenovAction technology. For a long time the pool had
been unusable due to its deteriorated condition and required major refurbishment. A
combination of RenovAction and Myrtha technology was selected for the complete
refurbishment of the failed concrete pool. The width of the pool was reduced, which
would provide area for the installation of a special needs, handicap access ramp.
Additionally, this solution provided an easy installation of the side wall Strahlenturbulenz

Installation of Myrtha components started from the side with the ramp for the disabled.
This side is completely built with Myrtha Technology and it is adjusted according to the
width of the ramp. After the installation of the base frame, the panels are then fixed to
the existing wall.
After having completed the installation of the panels, the overflow channel is positioned
and locked in place.
RenovAction panels are installed directly onto the walls of the other three sides of the
pool.
Between the RenovAction panels and the concrete pool wall, vertical spacers are
installed to allow for any imperfections in the concrete wall, followed then by the floor
membrane lining and installation of the mosaic lane markings.
