Singlewall land drainage pipe coils are corrugated and are available fully perforated or unperforated.
The fully perforated coils have three perforations per corrugation. This allows the water to penetrate the underground drainage pipe and filters it out into the ground whilst taking the majority to a final soakaway destination.
The unperforated coils are designed to take the water to a suitable collection point.
Both versions are supplied in a range of pipe sizes and each coil is supplied with one coupling.
The coils are manufactured from High Density Polyethylene (HDPE) to British Standard BS4962
