Unperforated twinwall is a strong pipe with a ribbed outer wall. Usually used in stormwater applications under paths, roads, railways, commercial and agricultural installations, the ribs in the outer wall give the pipe excellent compressive strength, enabling it to withstand large forces of pressure.

A range of bends, junctions and couplers are available for each pipe size. Seals should always be used in conjunction with these fittings when using twinwall drainage in for stormwater applications.
