SikaShield® P55 PE RT 4 mm

Anti-root plastomeric bituminous membrane surfaced with PE foil and flexible at -15 °C

SikaShield® P55 PE RT 4 mm is an APP modified bituminous waterproofing membrane with a thickness of 4 mm. It contains an anti-root additive, which allows the membrane to be in direct contact with the soil. It is reinforced with a non-woven polyester fabric dimensionally stabilised with glass fibre and is flexible at -15 °C. The top surface is coated with a polyethylene foil, which ensures the bond of the overlying layer. The underside of the product has a burn-off film for easy torch-application.
