Erosaweb geocell works by confining and stabilising the surface of weak soils, creating a honeycomb of interconnected polymer strips that form pockets to locate and strengthen the infill material.

Erosaweb can be laid over stable, steep slopes where the cell walls provide a tensile force, increasing the strength of the material and acting as mini-weirs to reduce run off velocity and soil loss. On a slope Erosaweb geocell is normally secured to the underlying material by frequent pinning, usually with steel pins. Where this is inadvisable or impossible, for instance when Erosaweb is installed over a geomembrane, the webs should be secured to a high-strength geogrid such as Trigrid.
