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.
Through wall / parapet outlet sleeves in TPE material designed to protect and waterproof drainage outlets on roofs, balconies and terraces.
Installed in the sandwich method between two layers of waterproofing membrane. They are durable and hard wearing and can tolerate hot melt and heat bonding (but not direct contact with a flame).
Manufactured with a large flange to present around the mouth of the outlet with perforations to allow bituminous and liquid membranes to ooze through to create an over-and-under bond. They can also be mechanically fixed beneath the waterproofing system. Always use a suitable primer before bonding.
Have a round spigot 500mm long to insert into the drainage hole of a parapet or structural wall. Can be used with horizontal or vertical outlets and roof drains.
Are used in conjunction with elbow and connectors and extension sections (see accessories section).
They are compatible with APP and SBS bituminous membranes.
They are measured as follows:
TPE Corner / Parapet / Through Wall Outlets
A is the diameter of the outlet drainage hole
B is the height of the (recessed) outlet drainage hole from the horizontal level
C is the inner diameter of the shank or outlet pipe at the bottom
D is the length of the pipe or shank
E is the width of the border flap or flange around the underside of the outlet hole
F is the height of the border flap or flange to the left and right, and above the outlet hole
G is the width of the flange or border flap across the face

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.
