Perforated Twinwall
Twinwall Drainage is manufactured from High Density Polyethylene (HDPE) for use in Surface Water and Stormwater applications.
The pipe itself is co-extruded, with ribs in the outerwall for added strength and a smooth internal bore to ensure a free flow. Our Twinwall systems are available either perforated or solid in a wide range of sizes.
