Perforated Land Drainage
Land Drainage Coils are used as a garden drainage pipe and they are manufactured from High Density Polyethylene (HDPE) to British Standard BS4962. The Land Drainage pipes are fully perforated to allow water to penetrate the underground drainage pipe and this will allow it to slowly filter out into the ground whilst the majority is taken to a final soakway destination. Land drainage coils are fully perforated, have a singlewall and are flexible with three perforations per corrugation. They are supplied in a range of pipe sizes and each coil is supplied with one coupling for jointing multiple coils.
