W-Joint Expansion Joints
The Rainbow W REJ M 60 is a water tight continuous membrane system for joints with movements up to 60mm in bridges, parking decks and other vehicle traffic. It uses mechanically fastened elastomeric anchor blocks with molded-in flat steel inserts to support heavy duty and high impact loads. The monolithic reinforced elastomeric gland is mechanically locked between the rubber anchor blocks and concrete slab. An epoxy Paste bedding adhesive is applied beneath the gland to enhance the product’s watertightness. The exposed surfaces of the Pioneer W REJ M 60 are non-metallic and skid resistant while resisting V deterioration. A tongue-and-groove connection at the end of each block prevents separation and uplift.
