Erosaweb GW is used to stabilise soil or fill on steep slopes. The Erosaweb is designed to provide stability where the soil fiction angle is insufficient. In addition, on steep slopes the polymer strips act as mini-weirs to reduce run-off velocity and soil loss.

Erosaweb can be used in conjunction with one of the range of Erosamats on very steep slopes. Using this system it is possible to place subsoil and topsoil on very steep slopes and prevent erosion on existing slopes.

Abgrid or looped geotextile is required to privide additional tensile strength on steep slopes where Erosaweb is used above geomembranes.

Access roads
Erosaweb GW vastly improves the bearing capacity of standard fill material. A 200 mm deep Erosaweb GW will provide approximately the equivalent foundation strength of 400 mm of crushed stone. This can be a huge saving in excavation and placement cost. Typical applications are access roads, railways, block paved loading bays, etc. Erosaweb GW is also proven as a reinforced grass surface for fire access roads.

Revetments
Erosaweb GW forms a flexible revetment structure for the lining of ditches and water channels. The web may be filled with concrete of crushed stone. The web is also also available with holes for Tendon ropes.

Retaining structures
Earth retaining structures are made with horizontal layers of Erosaweb GW placed and filled one on another. A pleasant floral feature can be created by planting in the front face pockets. This is an ideal low cost system for the construction of noise bunds, cut and fill sites, etc.
