The basis for the Contec rubber flat roof is our EPDM synthetic rubber or simply put "rubber". This extremely robust and elastic water-sealing is used on naked-, green-, energy-green and gravel roofs. We cut, weld and vulcanise our rubber precisely to size in our factory in Uetendorf. This is how we create Contec.proof, which is prefabricated up to 95 per cent to fit the size of your roof. This is then installed precisely by our assembly professionals in record time; the start of long-term protection for you, for your building, for generations to come.
