KEMPEROL® is a complete resin-based liquid waterproofing system. Applied wet-on-wet, KEMPEROL® bonds directly to virtually any substrate to provide a seamless, elastomeric, UV-stable membrane that cannot delaminate. This offers distinct advantages over partially bonded, layered liquid, sheet membrane, or hot-applied materials.

The key to the exceptional performance of KEMPEROL® waterproofing membranes is the technically superior resin formulation. This is the result of decades of research, chemical engineering and development by a company whose resources are 100% focused on providing liquid waterproofing and surfacing solutions.
