IMPERTEK - Диски для крепления туннельной гидроизоляции

TUNNEL DISCS are used to connect the diffuser felting to the tunnel's wall.‎ Once the discs have been attached to the wall, the waterproof PVC sheet is glued to the discs themselves by using special hot air blowers.‎ The discs must be glued with a special gun with an explosive charge.‎ Make sure there is a gap of about 70-80 cm.‎ The whole surface of the discs must be welded to the PVC sheet to ensure greater watertightness in the event of pressure from standing water.‎ They are highly flexible even at low temperatures.‎ Their physical and mechanical features remain over time.‎ They are compatible with PVC synthetic waterproof felts.‎ FLAT DISCS are available with or without a built-in iron washer.‎ The diameter of the pre-inserted washer is 21,75 mm with a hole in the middle of 5 or 6,4 mm.‎ Flat discs are also available with a tear-off system.‎ The flat discs with a tear-off system must only be glued on outside the holes designed for the tear.‎ Because of their special design, the RIBBED DISCS can be perfectly glued to the PVC sheet even on very uneven surfaces.‎ They also have a central groove to place the washer of the clamping nail.‎ Further info from manufacturer on Fixing discs for tunnel waterproofing IMPERTEK
