The Story
The DEKS Square Parapet Drain TPO provides a reliable horizontal drainage outlet for flat roofs using TPO membrane systems. Designed to discharge rainwater through parapet walls rather than through the roof deck, these drains create a secure waterproof connection between the roofing membrane and external rainwater pipework.
Manufactured from durable polymer compatible with TPO roofing membranes, the smooth flange allows thermal welding directly to the membrane to create a strong and watertight bond. The extended outlet passes through the parapet wall and connects to standard 90mm round rainwater pipes, making it suitable for a wide range of flat roof drainage installations.
Available in 65 × 100 / 90 and 100 × 100 / 90 outlet sizes, these parapet drains provide an effective solution for directing water safely away from flat roofs on residential, commercial, and industrial buildings.
