HY HD is a self-adhesive bituminous waterproofing membrane self-protected with HD polypropylene mesh.‎ This membrane with its excellent mechanical properties has been designed to waterproof bridges and viaducts, transit areas and ramps, where adhesion to the structure and resistance to enormous breaking and puncture loads is important.‎ The polypropylene mesh does in fact give the membrane extremely high mechanical strength.‎

HY HD is also able to resist high temperatures and consequently the hot binder can be laid on top of it without any protection at all.‎ Waterproof and Self-adhesive; High resistance to breaking and puncture loads; Excellent heat resistance; Self-sealing; Road binder can be applied hot directly on the membrane; Cold applied without use of flames.‎ Waterproofing of bridges and viaducts and anywhere mechanical strength is required; Waterproofing of carriageway transit areas, road ramps, car parks, elevated plazas, airport runways, road joints.‎
