Prefabricated thermal activated composite waterproofing membrane, composed of distilled bitumen and special synthesis polymers, which provide thermal adhesion properties to the lower face waterproofing compound. The waterproofing compound of the upper face allows for fast heat transmission to the lower face. The thermal activated waterproofing compound allows the product to be positioned and applied without the initial use of heat. PLURA THERMO AD PARKING is specifically developed for use on bridges, viaducts, parking decks and for all those applications where the use of road asphalt is required.
