Twinwall Land Drainage Pipe
Twinwall land drainage pipes are fully perforated and are available in a 3 metre ridged length. They are manufactured using 100% recycled high density polyethylene, and extruded by a twin extrusion process. This is where two layers are simultaneously extruded, giving the pipe a corrugated outer wall and smooth inner wall. It is extremely durable and can be buried between 0.5 & 10 metres deep. There are four perforations per corrugation which means there are 39 inset groves per metre with a slot length of between 15 - 30mm and a slot width of 2 - 2.5mm.
