Corrugated polypropylene (PP) stormwater pipe to AS/NZS 5065 with sealed rubber-ring bell–spigot joints and a smooth bore for high flow.
Plasdrain corrugated polypropylene pipe is a dual-wall stormwater drainage system for civil and infrastructure works. A smooth bore delivers high hydraulic performance while the corrugated outer wall provides strength at low weight. Sealed rubber-ring bell–spigot joints enable fast installation and reliable service life.
In simple terms: a tough, lightweight PP stormwater pipe that installs quickly, stays watertight and handles traffic loads with confidence.

Plasdrain corrugated polypropylene pipe is for gravity stormwater drainage in roads, rail, car parks, subdivisions, parks and general civil works where corrosion resistance and sealed joints are important.
DN225, DN300, DN375, DN450, DN525, DN600 and DN750 in nominal 6 m lengths. See the Dimensions tab for outside/internal diameters and effective lengths.
Dual-wall structured polypropylene (PP) — smooth inner bore for hydraulics; corrugated outer wall for strength-to-weight.
Bell–spigot rubber-ring (EPDM) push-fit joints for watertight seals.
Manufactured to AS/NZS 5065 (PP structured-wall, non-pressure). Design to AS/NZS 2566.1 and install to AS/NZS 2566.2.
Typical guidance from AS/NZS 2566-1: ~0.30 m (no vehicular loading), ~0.45 m (subject to vehicles, not roadway), ~0.60 m (sealed roadway), ~0.75 m (unsealed/embankments). The project designer/authority requirements govern.
Yes — when designed and installed to AS/NZS 2566 with appropriate cover and embedment for the application and DN.
Yes — couplers, bends, junctions, reducers, end caps and project-specific fabricated pieces on request.
Yes — conformity to AS/NZS 5065 and standard submittal documents are available with your quote on request.
