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.

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. comprehensive tools and services GEOWEB® system standard sizes Geoweb® sections are available in various cell types and depths, and section lengths to most economically meet project requirements. 2 ) 2 in G W 20 V 2 8 4.
