Benefits of Geocell perforations
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.
In vegetated systems, perforations allow roots to grow from cell to 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, and creating a better armored slope.
Earth Retention Perforations
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 create a better full-wall drained system that significantly reduces hydrostatic forces, resulting in more economical wall designs.
Load Support
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.
