Perforated Land Drainage Piping Coil Pipe (25M x 60mm) for field or garden underground water run-off, drying out and dispersal

Product Information

Perforated drain pipes are most commonly used to move rainwater away from the house so that it can drain elsewhere. Perforated pipes should be planned and installed with the help of a professional team to provide effective solutions to drainage issues. Unperforated land drain is for distributing collected surface water, as unlike perforated coils, they have no holes for water to drain into. Land drainage is available in either perforated or unperforated lengths, each working in a slightly different way. Generally the pipe manufacturer’s know roughly what the inflow capacity of the pipe will need to be as the pipe diameter will have a maximum conveyance capacity.

If either of these conditions is not met then the perforated pipe design is not adequate and the french drain will back up and may flood during the design storm event. For smaller standard garden lawns a 60mm perforated pipe would be used; for much larger garden areas, or smaller gardens with a big drainage problem, an 80mm perforated pipe can be used. The drainage should be installed at a low point in the affected area to allow it to drain surface water away to storm drain, or a Soakaway. In construction, it alleviates flooding and relieves static load on underground structures and retaining walls. Perforated land drainage pipe coils collect surface water through small holes cut in the dwells of the coil.A larger pipe or greater inflow capacity can also help to prevent the french drain from becoming clogged. To keep your garden looking its best through storms and heavy rain, land drain is the ideal solution. Perforated pipes comply with the Department of Transport Specification for Highway Works, which states the total area of drainage holes should not be less than 1000mm2 per metre length of pipe.

With no land drainage in built up areas, standing water can increase the static load on underground structures and retaining walls, by installing land drain to remove the excess water this relieves the pressure.
