OLDROYD® MultiSafe 1500 R

Flexible reinforced polyethylene membrane for water protection of tunnel and cavities

OLDROYD® MultiSafe 1500 R is a 1.5 mm thick reinforced membrane of flexible and strong polyethylene (LLDPE). It is specifically designed for waterproofing tunnel and cavities, in combination with shotcrete and meets the requirements for Type III by Handbook R510 (Chapter 8.1), Statens Vegvesen, Norway and Trafikkverket in Sweden. The rough surface is specifically designed to provide good adhesion to shotcrete in tunnels and cavities. It has a 150 mm wide weld bead on each side, marked with indication lines to ensure correct overlap. In combination with OLDROYD® RoadRunner reinforcement plug with spy this ensures optimal cover to the rebar grid and reduces vibration during the shotcrete process. This also minimizes the rebound loss of the shotcrete.

OLDROYD® MultiSafe 1500 R is based on OLDROYD Multi-Layer Technology™ and consists of three layers. It is white on the front towards the tunnel room with reinforced mesh and grey on the backside. It has a black signal layer to disclose damages and breakages.

OLDROYD® MultiSafe 1500 R is suitable for hot air welding of all joints and comes on a roll in widths up to 4,2 m and lengths up to 60 m.
