Maccaferri MacLine® RMH & RDH are geomembranes manufactured from quality high density polyethylene resins that comply with the most rigorous requirements established for their use. They have one or both surfaces roughened to a “sandpaper like” finish.
MacLine® RMH & RDH geomembranes contain not less than 97% of pure PE polymer and a balance not higher than 3% of carbon black, antioxidants and thermal stabilizers. The product does not contain plasticizers or fillers that could migrate over time. MacLine® RDH (both faces roughened) and RMH (only one face roughened) geomembranes have similar properties to the standard smooth products; the density of the added polymer to achieve the roughness can range from 40 to 140 gr/m2 on request. MacLine® RMH & RDH are manufactured under permanent quality control systems and comply with national and inter-national standards.
MacLine® TMH & TDH geomembranes are identical to the RMH and RDH geomembranes, except that they have a textured finish rather than a “sandpaper type” finish, on one or both two sides.
