DEKS Square Parapet Drain EPDM

The DEKS Square EPDM Parapet Drain provides a reliable horizontal drainage outlet for flat roofs using EPDM membrane systems. Designed to discharge rainwater through parapet walls rather than through the roof deck, this drain creates a secure and watertight connection between the roofing membrane and external rainwater pipework.

Manufactured from flexible EPDM-compatible polymer, the drain maintains excellent elasticity across a wide temperature range while offering strong resistance to UV exposure, ozone and environmental weathering. The smooth flange allows secure bonding with EPDM membranes, ensuring long-term waterproof performance at the roof surface.

Available in 65 × 100 / 90 and 100 × 100 / 90 outlet sizes, the rectangular outlet passes through the parapet wall and connects directly to standard 90mm round rainwater pipes, making it suitable for a wide range of flat roofing applications.
