Polymat TUNNEL is a Polymeric PVC-P waterproofing membrane with high tensile strengths & elongation, complies with the European harmonized Standard EN 13491
Polymat TUNNEL is a polymeric membrane made from a long - term proven PVC-P compound (Polyvinyl chloride compound with plasticizer) in a most modern Co-Extrusion process. The product may be either reinforced by a Polyester scrim for absorbing high tensile strengths and ensuring dimensional stability or non-reinforced membranes where additional elongation is required
• Exposed roofing systems (i.e. mechanically fastened industrial roofs)
• Ballasted roofing systems and Roof Gardens (Green Roofs)
• Single-ply refurbishment on roofs with existing bituminous waterproofing, using a separation layer of 300 g/m² polypropylene fleece or POLYMAT Roof UV-R FB300 (fleece back on bottom side, 300 g/m² non-woven) as a fully on bonded membrane in architectonic roof designs
• For ease of detail works (i.e. flashings, joints) use high UV resistant & fire retardant homogenous POLYMAT Roof UV-HM
Bitumat was founded in 1984 but its roots go back to 1975 when the founders became involved in the roofing waterproofing industry as dealer and applicator in Saudi Arabia for a major manufacturer from the U.S.A.
