RIW Flexiseal Pro

RIW Flexiseal Pro arrives as a two-part system, an epoxide that acts as a seamless waterproof solution. It comes bonded and cures brilliantly, completely free from solvents. Its main appeal lies in its innate flexibility and its intensive waterproofing against the elements. Applied following Flexiseal Pro Primer, this product is highly reliable for large scale basement tanking.

RIW Flexiseal Pro is tested and approved for use in Type A structuring. It’s built for use with basement types 1 through 3 and can be used in horizontal and vertical applications. RIW recommends this product be used for intensive projects facing tight deadlines. The fully bonded effect is highly reliable and gets to work quickly.

RIW Flexiseal Pro applies in double coats for vertical surfaces and provides effortless protection against water and vapour. It’s applicable through spray or via hand and will also resist UV and chemical splash to an extent. It will also adhere amazingly to substrate and will help to act as a crack bridger.

This product works well as a gas protection system as well as a water ingress guard. It is also one of several products eligible for a live discount as soon as you add it to the basket. Add RIW items to continue saving money while you shop.
