Tough and durable pre-cast corner fittings for drainage holes on roofs, balconies and terraces. The outlet pipe is either round or rectangular shaped and is slightly recessed, with a small drop from 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.

Bonded by using hot air gun (not direct contact to a flame).

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 heat bonded to the waterproofing membrane. There is a range of size options to accommodate varying pipe widths.
