Through-Wall Drainage Outlet for Resitrix EPDM Roofs
The Resitrix aluminium horizontal outlet is designed to form a secure through-wall drainage detail on flat roofs installed with the Resitrix EPDM membrane.
Manufactured with an aluminium chute and a factory-bonded Resitrix EPDM flange, the outlet integrates directly into the existing membrane. Heat welding the flange to the field sheet ensures a clean, system-compatible connection with minimal site fabrication.
Ideal for dispersing water through a parapet wall into a hopper head or external rainwater system.
What It’s Used For ▸
- Forming a horizontal through-wall outlet on Resitrix EPDM roofs
- Directing roof water into a hopper or external rainwater outlet
- Parapet wall drainage details
- New build and refurbishment flat roofing projects
Suitable for Resitrix EPDM systems only.
Not designed for non-weldable EPDM membranes.
Why It Matters ▸
Through-wall outlets are high-risk detailing areas. Poor integration between the membrane and outlet can lead to water ingress within the wall structure.
This outlet solves that by incorporating a Resitrix EPDM flange that is welded directly to the installed membrane, creating:
- A continuous waterproof layer
- Secure integration into the roofing system
- Reduced need for complex site detailing
The aluminium chute provides a rigid, durable pathway for water discharge while the welded flange maintains membrane integrity.
Installation Overview ▸
- Install and bond the Resitrix membrane in accordance with system guidance.
- Form the opening through the parapet wall.
- Position the aluminium chute.
- Heat weld the Resitrix EPDM flange to the main membrane, ensuring full bond across the perimeter.
Correct welding technique is essential for a watertight detail.

Roofer’s Perspective ▸
Factory-formed outlets save time and remove guesswork. Welding a Resitrix flange straight into the sheet gives confidence at one of the most vulnerable points on the roof.
