EPDM Through Wall Outlets

Tough and fully flexible pre-cast corner fittings for drainage holes on roofs, balconies and terraces. The outlet pipe is round and slightly recessed, with a small drop form the horizontal border flap to encourage the water to flow into the pipe immediately. It is also slightly angled to create a fall, encouraging faster flow of the water down the pipe.

They can be fitted to vertical downpipes at the edge of the retaining wall, or on a horizontal plane through the upstand or wall to then connect to the external downpipe. The corner fitting includes a flange which is sandwiched between two layers of waterproofing membrane and it is available with either a square or rectangular shaped outlet pipe.
