Wallbarn TPE Collar (Perforated Flange)

TPE Collars are designed to fit outside drain pipes and foul air pipes to ensure a complete waterproof seal on the roof deck.

Collars are fitted to pipework which emerges from the top of the concrete deck. These sorts of pipes include bad odour vents and stand pipes. It is critical that these pipes are completely waterproofed as they emerge from the deck as any water ingress will flow directly into an interior section of the building, such as a bathroom.

Collars will fit around the outside of an HDPE pipe (as opposed to the connectors and outlets which slot into the inside of a standard water pipe) and are secured using a jubilee clip or similar. They are again manufactured with a slightly conical shape, so that they are easier to fit, and also help direct water outwards away from the pipe and hole.

It is essential that the correct size of collar is chosen, as it needs to fit around the outer diameter of the HDPE pipe (which may be measured in Imperial measurements) but it should not be so large that gaps exist between the pip and collar, as this may cause movement.

The idea is that they completely surround the pipe.

The deck should be waterproofed around the pipe as it stands out from the deck, with a first coat or “patch”; and the collar is then fitted over the top whilst the first layer / coat is still tacky.

The membrane will ooze through the holes in the perforated flange. The second coat / layer of waterproofing is installed, with the membrane bonding to itself (in the same way as described for drainage connectors), so that the membrane is bonded under and over the collar, ensuring a complete seal.

The jubilee clip is fixed around the collar at the top end to secure the whole area.
