Description

TPE is a compound of rubber and polypropylene, developed as a cost effective way to waterproof and protect drainage holes and outlets on roofs and balconies in conjunction with bituminous waterproofing membranes. The material is tough, flexible and durable.

The resilient TPE material is UV stable and resistant to deterioration by normal atmospheric elements and ground salts. It can withstand temperature of 120°C and will not become brittle at very low temperatures.

These outlets, collars and vents are ideal for SBS and APP bituminous membranes, including built-up (felt), mastic asphalt, hot melt and other liquid applied membranes such as Fibreglass.

It is essential that the area around the drainage holes has a dedicated reinforced detail guarding the drainage hole. Contractors cannot simply rely on continuing a small piece of the waterproofing into the hole and “hoping for the best”.

The key range drainage outlet connector is manufactured with a perforated flange, which is designed so that the unit is sandwiched between two layers of bituminous waterproofing membrane. The material can tolerate the application of hot liquid or even a torch-gun coming into contact with it. The membrane will ooze through the holes to bond both layers to each other, giving an extremely secure “over and under” bond.

The shaft of the outlet then connects to the HDPE drain pipe by slotting inside it. This ensures that the area is completely waterproofed around and into the drain pipe, so that there is no risk of water creeping behind the drainage hole and causing a leak.

The spigot pipe is round and slightly recessed, with a small drop from the horizontal border flap to encourage the water to flow into the pipe immediately and not pond around the mouth and possibly creeping back behind the outlet. The pipe or shank is slightly angled down to create a fall, encouraging faster flow of the water down the pipe. The shank itself is 500mm long, so it can cross through a large section of wall. Extension shanks are available if required.

These corner units can be fitted to either 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.
