GeoRidge is a permeable plastic berm that has been designed for erosion and sediment control. It is a lightweight, sustainable alternative to conventional check dams. Utilized with Erosion Control Blankets, GeoRidge is effective in reducing water velocity, trapping sediment and aiding in vegetation.

GeoRidge (Standard)

GeoRidge is constructed of a durable UV stabilized High Density Polyethylene (HDPE), giving it very good resistance to UV and normally occurring soil conditions. GeoRidge (standard) should be removed once vegetation is established – it can be reused for future projects.

GeoRidge Bio (Biodegradable)

GeoRidge Bio is an excellent alternative to Nilex’s standard GeoRidge product. Rather than removing once vegetation has been established, GeoRidge Bio breaks down over time. With the incorporation of technologically advanced additives, GeoRidge Bio check dams will degrade over an 18 to 24 month period (degradation time is dependent upon environmental conditions). The interaction with environmental conditions and naturally occurring micro-organisms causes degradation of the material.
