ABOUT TUNNEL CONSTRUCTION
Carbofol® geomembranes for tunnel construction Geosynthetic materials manufactured from polyethylene (PE), which is highly resistant to chemicals and
ecologically safe to the environment, meet highest requirements. Carbofol® tunnel geomembranes consist of PE-VLD (polyethylene - very low density) or PELLD (polyethylene - linear low density). Due to the careful resin selection, Carbofol® tunnel geomembranes are highly flexible and free from plasticizer.
