Plasdrain™ - Durable and Efficient Stormwater Drainage Solutions for All Environments

Plasdrain™ pipes are dual-walled, corrugated polypropylene pipes for non-pressure applications, manufactured in accordance with AS/NZS 5065.

The unique extrusion process offers the ability to utilise recycled material of varying sources and quantities.

Utilising the latest co-extrusion techniques, Plasdrain™ is manufactured with a smooth bore for the highest hydraulic performance and a corrugated outside wall for the highest stiffness to weight ratio.

The in-line bell and spigot joint, paired with light weight design provides for quick installation.

Polypropylene ensures high strength to weight ratio, high stiffness, and toughness. Plasdrain™ can be installed in trafficable areas including under road pavements and non-trafficable areas. Plasdrain™ is sensitive to the environment, by firstly utilising recycled polypropylene raw material and secondly through efficient design by using less material than comparable drainage pipes, long life cycle and light weight reducing the CO2 emissions from plant and heavy vehicles to transport and install.

Plasdrain™ is less likely to crack than rigid pipe, resulting in less leakage and consequential environmental issues. Rigid pipes that do crack require plastic lining to reseal.

Plasgain Plasdrain™ provide a modern stormwater drainage system for the modern infrastructure project.

Chemical Resistance

Plasdrain™ polypropylene pipes are resistant to corrosion by aggressive soils and substances that can wash through the stormwater drainage system. Polypropylene resins are highly resistant to solvents and chemicals. They are resistant to weak inorganic acids, organic acids, alcohols, ammonia and oxidising salts and suffer from breakdown only when exposed to strong inorganic acids such as fuming nitric acid at room temperature and 98% sulfuric acid at 600°C, both of which are highly unlikely to pass through the stormwater system. Chemical resistance is affected by concentration, temperature, period of contact and stress.
