Kmat is a three-dimensional erosion prevention geomat obtained from extruded syntheticmonofilaments tangled and welved where they cross.

Because or its three-dimensional structure with a high void ratio (>90%)Kmat can be saturated with granular material,generally vegetal soil.

During the production process standard geomats can be coupled with other types of geosynthetics in order to enhance specific characteristics that are needed for given applications. The following products can thus be obtained :
