DiProtec® KSK is a bitumen cold applied self-adhesive waterproofing membrane which has been specially optimised for use on balconies and terraces. Special material characteristics prevent creasing and provide an optimum flat surface. The double-sided silicone paper prevents the membranes from sticking to each another. A special primer stops moisture from moving up out of the substrate, and prevents bitumen from washing out. DiProtec® KSK can be used with all types of AquaDrain® drainage mats and the TerraMaxx® DS systems.


  • Optimum flat surface and stability.
    Thanks to a special combination of materials.
  • Self-adhesive for easy installation.
    Tear-off double-sided siliconised paper prevents the membranes from sticking to each another.
  • Can be used as waterproofing membranes beneath all types of AquaDrain® drainage mats and TerraMaxx® systems.
  • Waterproofing in accordance with DIN 18531-5 for ground contact terraces, balconies, loggias and walkways.
