Stopaq® Mortar WR is a cement based, rapid setting mortar to be used in conjunction with Stopaq® sealing products for waterproofing of pipe and cable wall inlets. Stopaq® Mortar WR is suited as mechanical support and as waterproof barrier for pipe- or cable wall penetrations filled with Stopaq® 2100 Aquastop, Stopaq® 4100 Putty or Stopaq® Paste CZ/CZH/CZHT. It is especially designed as a waterproofing barrier in wall inlets that are frequently exposed to huge amounts of water. It bonds very well to concrete and brick and protects against water penetration through pores and capillaries.
