The Story
The DEKS Square Parapet Drain TPE provides a reliable horizontal drainage outlet for flat roofs where rainwater needs to discharge through a parapet wall rather than directly into the roof deck. Designed to connect the roofing membrane to external rainwater pipework, this drain allows water to exit through the wall while maintaining a secure waterproof seal at roof level.
Manufactured from flexible TPE polymer, the drain offers excellent durability and long-term performance in demanding weather conditions. The wide flange enables secure bonding with compatible roofing membranes, while the extended outlet pipe allows installation through parapet walls up to approximately 400mm thick.
Two section sizes are available, both designed to connect to 90mm round rainwater pipework, making them suitable for a wide range of flat roof drainage systems.
