MacMat are made of synthetic material filaments, tangled together to form a highly deformable layer 10-20 mm thick, featured by a very high porosity (greater than 90% on average). MacMat R - Steel is a reinforced geomat obtained by a polymer made threedimensional matrix extruded onto a double twisted steel woven mesh. Double twisted woven mesh used in production of MACMAT R – STEEL can be with or without Polymeric coating. MacMat R - Polymer is a reinforced geomat obtained by a polymer made threedimensional matrix extruded onto a polymeric woven geogrid. MacMat products can be used on slopes, along the banks of canals and river courses, or to convey liquids (drainage) in association with geotextiles and/or geomembranes.
