Geogrid woven of polymer fibers for slope protection
Efficiency and scope of application
Geospan SL geogrids are effectively used to protect slopes of embankments, cuts, and bridge cones against water and wind erosion. The geomaterial is fixed on the slope, after which it is covered with fertile soil with seeds of perennial grasses. Due to the lightness of the Geospan SL material, it can be used on slopes of increased steepness (1:1 or more).
