The basis for our extremely robust and elastic flat roof waterproofing is EPDM synthetic rubber or simply "rubber". This is used as waterproofing on bare, green, energy-green or gravel roofs.
In our workshop in Uetendorf, the high-quality EPDM rubber mass-produced suit is prefabricated for your roof, including roof penetrations and terminations. In this way, up to 95 percent of the sustainable, long-lasting and ecological waterproofing is created. Thanks to the large elongation at tear, the Contec.proof rubber copes with the enormously large temperature fluctuations and is still very ductile even after 50 years.
