ARDEX WPM 3000X Shelterseal is a cutting-edge self-adhesive bituminous waterproofing membrane designed to provide exceptional protection against water ingress. Its unique construction incorporates a cross-laminated high-density polyethylene (HDPE) film, which not only enhances the membrane's self-adhesive properties but also imparts remarkable dimensional stability and elongation characteristics, making it perfect for below-ground applications. The addition of a bituminous compound further enhances its mechanical strength, durability, and resistance to heat, shape deformation, and chemicals.
