MultiJoint

RIW MultiJoint is a closed cell, cross linked Ethylene Vinyl Acetate copolymer waterproof EVA foam. The manufacturing process gives a nitrogen blown, impermeable, closed cell foam. The product is waterproof and resistant to salts and most chemical attack. It also has good UV resistance and is therefore suitable for use in exposed exterior applications.

RIW MultiJoint waterproof EVA foam has been designed for use in all types of construction movement joints and construction gaps to provide a waterproofing system between the structural elements. Movement capability of up to 90% of the construction gap is achieved, and the product is chemically bonded to each structure, maintaining the waterproofing of the joint in Podium / Plaza Decks, Car Parks, Foot / Road bridges, Stadiums and Sports Arenas, Shopping Malls, Airports, Roofs and Building Facadès.
