GEOMATS, MTD-EXTRAMAT GEOMATS

and MTD-EXTRAMAT mats are the 3D water-proof structures made of polymer materials and/or other synthetic or natural elements connected with each other by thermal, mechanical or other methods.

The geomats should be used in accordance with the design solutions as reinforce components to provide stable vegetation for preventing erosion of the slopes, side ditches, excavations, bridge cones, slide slopes, gullets, structures in the rockfall areas and water-logged soils, and shore lines; and to restore the topsoil on rocky and flat surfaces.
