channel protection system
slope & shoreline protection system
earth retention system
The Geoweb® channel protection system provides a wide variety
of flexible protection treatments for open channels and hydraulic
structures. The system provides stability and protection of channels
exposed to erosive conditions ranging from low-to-high flows
either intermittent or continuous.
The Geoweb® slope and shoreline protection system
confines, reinforces and restrains the upper soil layer and
infill controlling down-slope movement and slippage due to
hydrodynamic and gravitational forces.
The Geoweb® system, when layered, becomes an earth
retention system meeting all project-specific structural
requirements. The system allows for construction flexibility
and provides aesthetics through a completely vegetated face.
Horizontal terraces are formed where vegetation can flourish
in the exposed outer cell infill. The system captures rainwater
and controls groundwater evaporation, creating a more
natural environment for vegetation.
•Provides effective slope protection and structural
confinement of granular materials such as sand, gravel and
larger rock or stone.
•Greatly improves the hydraulic performance of conventional
protection materials such as aggregate, rip-rap and
vegetation by confining them within the cellular structure.
•Can produce a flexible concrete slab for a low-friction,
armored channel lining.
•Can be designed for specific site conditions based upon
compatibility with local environmental, ecological and
aesthetic requirements, maximum anticipated flow, and
associated hydraulic stresses.
•Surface roughness and hydraulic efficiency of the lining system
can be changed to control flow.
TYPICAL APPLICATIONS
•swales and drainage ditches
•storm water diversion or containment
•process water channels
•spillways/down chutes/drop structures
•culvert outfalls
•Becomes a flexible concrete mat with built-in expansion
joints when cells are infilled with concrete.
•Meets a wide range of structural and hydraulic requirements
as single or multi-layered systems.
•Creates additional stability by integrating tendons on
steeper slopes and shoreline embankments or when a
geomembrane or hard soil/rock surface prevents anchoring
with stakes.
TYPICAL APPLICATIONS
•cut or fill embankment slopes
•geomembrane protection
•shoreline revetments
•landfill linings and covers
•storm water/waste
water lagoons
•dam faces and spillways
•abutment protection
•containment dikes & levees
load support system
The Geoweb® load support system stabilizes the selected
infill and provides solutions in three key areas: 1) a load
distribution system over weak soils, 2) base stabilization
for paved surfaces and 3) surface stabilization for unpaved
surfaces. Confined infill in the system produces a stiff layer
with high flexural strength.
TYPICAL APPLICATIONS
•Maintains structural stability against all loading through
its mass and frictional values of the infill.
•bioengineered walls
•Meets site challenges when subgrade soils are compressible
or construction is in difficult-to-access locations.
•dike & levee protection
•Creates blending with any environment through use of tan,
green or special-colored facia panels.
•steepened embankments
•culvert headwalls
•landscape development walls
•vegetated channel structures
•sound barriers
•intermittent or continuous/low to high flow channels
•Significantly minimizes surface rutting.
•Distributes loads laterally and reduces vertical deflection
and subgrade contact pressures.
TYPICAL APPLICATIONS
•Controls shearing and lateral movement of the coarse
and permeable infill material.
•permanent and temporary site access roads
•With open aggregate infill, reduces storm water runoff
and creates on-site water detention/retention basin.
•intermodal/port facilities
•In most cases, the Geoweb® system doubles the effective
structural number for load support.
•permeable, load-supporting surfaces
•transportation/storage yards
•roadway shoulders
•stabilized drainage layer
•Subgrade drainage requirements and deformation potential
within the structure can also be addressed.
•stabilized base for asphalt/modular block pavements
•track ballast and subballast structures
•trails and walkways
•boat ramps and low water crossings
•foundation mattresses & pipeline protection
•trench inverts
channel, slope, and shoreline
•Perforations facilitate parallel slope drainage
of the infilled cell. In saturated conditions, the
removal of excess water increases infill friction,
reducing down slope sliding forces, resulting in
a more stable system.
load support
earth retention
•In vegetated systems, perforations allow roots to
grow from cell-to-cell creating greater vegetative
stability against short-term hydraulic events.
•With aggregate infill, perforations create greater
frictional resistance between infill materials and
the textured/perforated cell wall, resulting in
greater resistance to hydraulic scour.
•With concrete infill, perforations allow infill to
interlock with the cell walls, increasing frictional
resistance, creating a better armored slope.
benefits of
•Perforations improve frictional interaction between
the textured/perforated cell wall, creating greater
back wall friction, potentially reducing horizontal
destabilizing forces and increasing vertical
stabilizing forces.
perforations
•Perforations create a better full-wall drained
system that significantly reduces hydrostatic forces,
resulting in more economical wall designs.
•Perforations and a textured surface increase the
friction angle between aggregate infill and the
cell wall, generating better aggregate lockup
and greater overall load distribution.
• Perforations facilitate lateral cell-to-cell
drainage of excessive ground and surface
water, reducing the negative effects of
trafficking over saturated soils.

infill and provides solutions in three key areas: 1) a load
distribution system over weak soils, 2) base stabilization
for paved surfaces and 3) surface stabilization for unpaved
surfaces. Confined infill in the system produces a stiff layer
with high flexural strength.
TYPICAL APPLICATIONS
•Maintains structural stability against all loading through
its mass and frictional values of the infill.
•bioengineered walls
•Meets site challenges when subgrade soils are compressible
or construction is in difficult-to-access locations.
•dike & levee protection
•Creates blending with any environment through use of tan,
green or special-colored facia panels.
•steepened embankments
•culvert headwalls
•landscape development walls
•vegetated channel structures
•sound barriers
•intermittent or continuous/low to high flow channels
•Significantly minimizes surface rutting.
•Distributes loads laterally and reduces vertical deflection
and subgrade contact pressures.
TYPICAL APPLICATIONS
•Controls shearing and lateral movement of the coarse
and permeable infill material.
•permanent and temporary site access roads
•With open aggregate infill, reduces storm water runoff
and creates on-site water detention/retention basin.
•intermodal/port facilities
•In most cases, the Geoweb® system doubles the effective
structural number for load support.
•permeable, load-supporting surfaces
•transportation/storage yards
•roadway shoulders
•stabilized drainage layer
•Subgrade drainage requirements and deformation potential
within the structure can also be addressed.
•stabilized base for asphalt/modular block pavements
•track ballast and subballast structures
•trails and walkways
•boat ramps and low water crossings
•foundation mattresses & pipeline protection
•trench inverts
channel, slope, and shoreline
•Perforations facilitate parallel slope drainage
of the infilled cell. In saturated conditions, the
removal of excess water increases infill friction,
reducing down slope sliding forces, resulting in
a more stable system.
load support
earth retention
•In vegetated systems, perforations allow roots to
grow from cell-to-cell creating greater vegetative
stability against short-term hydraulic events.
•With aggregate infill, perforations create greater
frictional resistance between infill materials and
the textured/perforated cell wall, resulting in
greater resistance to hydraulic scour.
•With concrete infill, perforations allow infill to
interlock with the cell walls, increasing frictional
resistance, creating a better armored slope.
benefits of
•Perforations improve frictional interaction between
the textured/perforated cell wall, creating greater
back wall friction, potentially reducing horizontal
destabilizing forces and increasing vertical
stabilizing forces.
perforations
•Perforations create a better full-wall drained
system that significantly reduces hydrostatic forces,
resulting in more economical wall designs.
•Perforations and a textured surface increase the
friction angle between aggregate infill and the
cell wall, generating better aggregate lockup
and greater overall load distribution.
• Perforations facilitate lateral cell-to-cell
drainage of excessive ground and surface
water, reducing the negative effects of
trafficking over saturated soils.
channel protection system
slope & shoreline protection system
earth retention system
The Geoweb® channel protection system provides a wide variety
of flexible protection treatments for open channels and hydraulic
structures. The system provides stability and protection of channels
exposed to erosive conditions ranging from low-to-high flows
either intermittent or continuous.
The Geoweb® slope and shoreline protection system
confines, reinforces and restrains the upper soil layer and
infill controlling down-slope movement and slippage due to
hydrodynamic and gravitational forces.
The Geoweb® system, when layered, becomes an earth
retention system meeting all project-specific structural
requirements. The system allows for construction flexibility
and provides aesthetics through a completely vegetated face.
Horizontal terraces are formed where vegetation can flourish
in the exposed outer cell infill. The system captures rainwater
and controls groundwater evaporation, creating a more
natural environment for vegetation.
•Provides effective slope protection and structural
confinement of granular materials such as sand, gravel and
larger rock or stone.
•Greatly improves the hydraulic performance of conventional
protection materials such as aggregate, rip-rap and
vegetation by confining them within the cellular structure.
•Can produce a flexible concrete slab for a low-friction,
armored channel lining.
•Can be designed for specific site conditions based upon
compatibility with local environmental, ecological and
aesthetic requirements, maximum anticipated flow, and
associated hydraulic stresses.
•Surface roughness and hydraulic efficiency of the lining system
can be changed to control flow.
TYPICAL APPLICATIONS
•swales and drainage ditches
•storm water diversion or containment
•process water channels
•spillways/down chutes/drop structures
•culvert outfalls
•Becomes a flexible concrete mat with built-in expansion
joints when cells are infilled with concrete.
•Meets a wide range of structural and hydraulic requirements
as single or multi-layered systems.
•Creates additional stability by integrating tendons on
steeper slopes and shoreline embankments or when a
geomembrane or hard soil/rock surface prevents anchoring
with stakes.
TYPICAL APPLICATIONS
•cut or fill embankment slopes
•geomembrane protection
•shoreline revetments
•landfill linings and covers
•storm water/waste
water lagoons
•dam faces and spillways
•abutment protection
•containment dikes & levees
