RIW Flexiseal is a solvent free thixotropic liquid based on urethane pre polymers , which on contact with atmospheric moisture, cures to give a continuous tough rubber like coating.
RIW Flexiseal, as a system, is used in all situations where a high performance tanking or damp proof membrane is required. Suitable substrates include concrete, masonry, steel, asbestos cement, timber, sprayed polyurethane foams and expanded polystyrene such as ICF systems.
When designing Type A structures ( as classified in BS 8102:1990 ), the product applied correctly is capable of providing the levels of protection required for Grades 1, 2, 3 & 4 basements
RIW Flexiseal is not to be used in contact with potable water systems.
Subject to normal conditions of use RIW Flexiseal will provide an effective barrier to the transmission of liquid water and water vapour for the life of the structure.
