Ribbed discs

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.

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.
