Erosion of slopes can be avoided very well with entangled mesh structures, particularly during vegetation, because the soil which is filled into the three-dimensional static structure of the randomly entangled mesh is securely held in place and relatively resistant to washing out.

Three-dimensional geosynthetics and composites prevent the removal of soil particles by water and wind. In nature, it is the plants with their roots that prevent the soil from being carried away. The natural formation of vegetation layers, which often takes years, will be accelerated and enhanced by the use of erosion control matting.
