RIW has been a generic term for waterproofing solutions for over 90 years; our name even stands for ‘Remember It’s Waterproof’ from an old ad slogan in 1921. RIW offers the most expert technical advice for commercial waterproofing and damp proofing applications above, below and at ground level. From basement tanking, podium decking, raised access floors and plant rooms to lift pits and movement joints – RIW provides the best design advice on your waterproofing strategy.
