Erosaweb works by confining and stabilising the surface of weak soils by 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 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.
Using Abweb it is also possible to strengthen sub-bases and reduce foundation stone thickness under loaded areas by up to 50%.
Earth retaining walls can be formed with horizontal layers of Erosaweb filled and placed one on another. A specific retaining wall product is available as Webwall.
