The Story
The DEKS Parapet Drain Round PVC provides a reliable horizontal drainage solution for flat roofs using PVC membrane systems. Designed to discharge rainwater through parapet walls, these drains create a secure and watertight connection between the roofing membrane and external rainwater pipework.
The smooth flange allows thermal welding directly to PVC membranes, ensuring a strong and durable bond at the roof surface. Manufactured from high-quality polymer, these drains offer excellent resistance to weathering, UV exposure and environmental conditions while maintaining long-term performance.
Featuring a round outlet pipe, the drain passes through the parapet wall and connects directly to standard round rainwater pipework of the same diameter. Available in a range of sizes, these parapet drains are suitable for both residential and commercial flat roofing applications.
