RIW Protection Board is a flat sheet, made of organic fibres saturated with bitumen.
RIW Protection Board is used for the protection of waterproof membranes against mechanical damage, pedestrian or vehicular traffic and abrasion caused by backfilling. The board is resistant to water, ground salts and most corrosive chemicals.
The product can be easily cut with a ‘Stanley’ knife or similar.
The boards should be laid butted together, with joints taped using RIW Sheetseal if required.
