Aluminum expansion joint SOPRAJOINT®

SBS asphaltelastomericfor flooring

SOPRAJOINT® is a flexible SBS elastomeric bitumen waterproofing strip (width: 45 cm) with a polyester fabric exclusively used for expansion joints in horizontal or vertical directions. The topside is covered with an aluminium foil at the center protected by a silicone release film. The underside is covered with a thermofusible film. SOPRAJOINT® must be used with BANDE LM (35mm thick and 150mm wide flexible mineral wool strip) to support the SOPRAJOINT® membrane. SOPRAJOINT® ensures the continuity, for horizontal and vertical directions, of waterproofing systems above expansion joints, with or without thermal insulation or on the upstands of the structure. SOPRAJOINT® must be applied only by heat welding or torch-on techniques. Hot bitumen must not be used in the bonding process. For car parks, DALLE SOPRAJOINT® TM must be used for the protection.
