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 rectangular shaped spigot 425mm long to insert into the drainage hole of a parapet or structural wall. Can be used with horizontal or vertical outlets and roof drains.

Two clear design options: a flat flange which presses directly up to the wall or a 45° face which acts as a fillet.

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

• TPE Through Wall Outlets (Ribbed Flange)

EPDM through wall outlet covers and sleeves to protect and waterproof drainage outlets and pipes placed close to walls and upstands. Bonded to the waterproofing membrane itself to increase the seal and give a ”double skin” to the waterproofing system at the vulnerable areas.

Now available with square shaped and rounded spigots for use with a variety of drainpipes and outlet sections.
Installed in the sandwich method between two layers of waterproofing membrane. They can be welded, bonded with adhesive or mechanically fixed to compatible rubber membranes using the sandwich technique.

To ensure a proper seal it is recommended that the waterproofing membrane is beneath and above the rubber profile. Always use a suitable primer before bonding.

EPDM outlets are now available in three clear designs:

• The right angled flange unit with a rounded spigot;
• The flat flange unit with a square spigot;
• Outlet with a 45° angled fillet style flange and a square spigot.

They are extremely tough and flexible, resistant to high and low temperatures and can be used on horizontal and vertical drain systems. Are used in conjunction with elbow and connectors and extension sections (see accessories section).
Operating temperature: Minus 20°C to Plus 70°C.

A is the height of the outlet drainage hole
B is the width of the outlet drainage hole
L is the length of the shank or outlet pipe
F1 is the width of the border flap or flange around the underside of the outlet hole
F2 is the height of the border flap or flange to the left and right, and above the outlet hole
F3 is the width of the flange

EPDM through wall outlets with a circular spigot, suitable for bituminious or rubber membranes with a smooth flange are designed for mechanical fixing or for using adhesive. Always use a compatible primer on outlet and surface before starting application.

Please refer to waterproofing manufacturer for correct application method and guidance on compatible adhesives, primers and waterproofing membranes.

EPDM through-wall outlets are also available for drainage holes in the junctions between the horizontal and vertical plane with a rectangular drainage outlet mouth. Flange is mechanically fixed or sealed with a compatible adhesive.

Circular mouth corner / parapet / through wall outlets

Our circular mouth outlets are measured as follows:

D1 is the diameter of the outlet drainage hole
D2 is the height of the (recessed) outlet drainage hole from the horizontal level
D3 is the inner diameter of the shank or outlet pipe at the bottom
L is the length of the pipe or shank
F1 is the width of the border flap or flange around the underside of the outlet hole
F2 is the height of the border flap or flange to the left and right, and above the outlet hole
F3 is the width of the flange or border flap across the face

Please note that the length of the shank is 500mm, slightly longer than the shank of the rectangular mouth outlets.

Rectangular mouth corner / parapet / through wall outlets

These outlets are available in two versions, with the mouth of the outflow pipe being either 65 x 100mm, or 100 x 100mm for a greater amount of water flow

The rectangular corner fitting is available in the following sizes:

A is the height of the outlet drainage hole
B is the width of the outlet drainage hole
L is the inner length of the shank or outlet pipe
F1 is the width of the border flap or flange in front of the outlet hole
F2 is the height of the border flap or flange above the outlet hole
F3 is the width of the flange or border flap across the face

The shank is 425 mm long. Connections can be made easily to HDPE pipework for seamless, waterproof drainage systems.
