ARCO ANTIROOT are prefabricated modified polymer-bitumen membranes whose compound is composed of distilled bitumen, polymers and special chemical additives againts root penetration, reinforced with a Woven non Woven polyester fabric with longitudinal reinforcing threads. Those chemical additives resist at high temperatures, are not migrating into the soil and are not washed out by the water.
The modified compound offers good ageing properties, cold flexibility
(-50C), durability and elasticity, while due to the polyester reinforcement doubled with glass fibre longitudinal reinforcing threads, offers a better dimensional stability, a good static and dynamic puncture resistance, tensile strength, both longitudinal and transversal, and ultimate elongation.
ARCO ANTIROOT are supplied with sand, TNT (polypropylene mat) or mineral slate chips which are available in natural or coloured version. This mineral finish acts as a weathering surface and enhances the aesthetics after application. A 10 cm side selvedge and a 15 cm end lap selvedge is provided to allow easy alignment of the membrane during application.
The lower face of ARCO ANTIROOT is backed by a special polyethylene burn-off film which melts during torching and prevents the roll from sticking to itself. The correct application temperature is visible from the embossed surface of the membrane which is below the burn off film, when the correct temperature is reached, this embossment melts also helping vapour diffusion and avoiding blistering.
ARCO ANTIROOT is specially indicated for use in underground waterproofing like tunnels, foundations or pipes insulation, as much as for roof gardens.
The main characteristic of the ARCO ANTIROOT membrane is granted by the PREVENTOL BAYER additives. |
