Perforated Land Drain and Filter Sleeve Kit - 60mm (O.D.) x 50mtr Coil

A complete land drainage kit comprising a 60mm (O.D.) x 50mtr coil of perforated land drain and a matching filter sleeve, supplied together.The perforated pipe collects and carries away excess ground water, while the filter sleeve fits over the pipe like a sock to stop sand and silt particles clogging the perforations. Larger particles bridge against the fabric, improving the permeability of the surrounding backfill andndash; a low cost alternative to expensive filter materials. The sleeve is easily fitted by one person.
