ANTIROCK® RSI membrane is a torchable partial bonded waterproofing membrane made from polymer modified bitumen (SBS elastomer) with a non-woven polyester reinforcement mesh (180g/m²).


The underside of ANTIROCK® RSI permits the partial bonded due to bituminous welding stripes alternated by non-welded sand stripes. The top surface is protected by slate chippings. The grey-coloured slate chippings provide excellent mechanical protection during the application of coated materials as well as protecting against UV rays during the construction phases. It therefore does not require any form of temporary protection. CIVILROCK® attaches the highest importance to the quality of its products. This is why we operate a quality assurance system according to ISO 9001 BSI certified.

- used directly on car parks underneath asphalt,
- partial bonded (decrease of blisters risks),
- resistant to UV rays,
- flexible when cold and hot,
- good weldability,
- high mechanical resistance,
- high puncture resistance.


ANTIROCK® RSI is mostly used on car parks for light vehicles directly underneath one or more layers of asphalt bituminous mixtures. The membrane is welded onto a substrate prepared with primer: ELASTOCOL® 500 TP, or AQUADERE® TP (solvent-free primer). The asphalt is laid directly onto the membrane. The interest of semi-loose is the decrease of blisters risks as part of the non adhesive membrane allows degassing from the concrete. The welding is performed like adherent membranes: by heating but without smoothing the membrane onto the substrate. The primed substrate and the bituminous sheet are heated alternately. The welding is only done manually with a flame. A 90mm selvedge ensures easy overlapping.
