Hydrophilic, Expanding Rubber Waterstop for Watertight Joints and Transitions
Mapestrip™ 25 is a pre-formed hydrophilic rubber strip, with an acrylic polymer base specially designed to form watertight construction joints. Controlled volumetric expansion reduces the risk of concrete spalling. Mapestrip™ 25 is ideal for horizontal and vertical construction joints and penetrations though slabs and walls.
