Waterproofing is often one of the trickiest stages in large-scale construction. However, RIW Sheetseal 226 allows you to create robust, reliable barriers with minimal effort. Perfect used either to help tank basements and cellars or to membrane ground floors, it is self-adhesive and extensive. It arrives with a bitumen coating and is, for all intents and purposes, a highly versatile polyethylene filming solution.

RIW Sheetseal 226 is a solution designed ideally for Type A structures, providing waterproofing membranes for basements grading 1 to 3. It can be used for internal and external tanking and requires no need for drying. It is resolutely and consistently thick and helps lock out water and vapour alike. It’s widely used in public buildings and high traffic areas, such as schools, museums, and offices.

RIW Sheetseal 226 is highly flexible and adaptable, and moreover, it is straightforward to work with. Removing the need for extensive tanking, this single sheet can effectively waterproof a whole basement. It is a one-seal solution providing your ground floor is open and unobstructed. It’s also developed to self-heal and will resist sulphates.

All items are usually available for next working day delivery if ordered before 11am, and that we do our best to keep it that way. However, sometimes the delivery slots are full before 11am, so it’s not always guaranteed. If it happens, we will deliver on the following working day.
