Polybridge combined with either a mastic asphalt protection or a road asphalt layer offers a perfect solution to provide park decks, bridges and tun-nels with a bonded waterproofing system.

Polybridge consists of an impregnated carrier with combination of polyester and glassfleece, covered at the bottom side with flexible poly-mer bitumen. The finish of the top surface of this membrane, talcum, admits direct applica-tion of road asphalt at a temperature of max. 160°C-200°C or mastic asphalt with a tempera-ture of approx 250 °C. The positioning of the carrier close to the up-per surface of the membrane ensures a thor-ough adhesion between membrane and sub-strate.
