Buy Perforated and Un-perforated Land Drainage Pipe Coils in Sizes from 60-160mm – Black
Constructed for the effective management of land water drainage, serving the agriculture and the leisure and sport businesses, our systems are manufactured from HDPE or uPVC and are kitemarked to BS 4962. They are flexible, powerful and easy to install providing water stream.
Unlike underground ducting where colour is an indicator of what is inside the duct, colour is irrelevant when it comes to Land Drainage Pipes. Most are manufactured in either a black or a yellow colour.
Land Drainage Pipe is the term given to perforated drainage pipes that are used to cure waterlogged areas in gardens or other landscaped areas such as sports fields.
They are pipes that allow water to enter through perforations. The water flows away to a suitable disposal point such as a soakaway, a storm drain or a stream. You should check with the local authority to confirm that your preferred point of outfall is permissible. Land Drainage Pipe Coils shouldn’t be attached without the consent of the Local Authority to a foul or combined drain, and in these circumstances the relationship must incorporate a trap.
In waterlogged areas, carefully packed soil particles hold the water set up — there is no escape route for the water. By replacing the majority of these soil particles with granular material such as shingle, a route for the water is created, since the gap between each piece of shingle is greater than the gaps between the original soil particles.
Gravity takes the water and hold then picks up speed, to the land drain and channelling downwards itself via the perforations in the land drainage pipe. Once inside the pipe, which is laid at a gradient that is gentle, the water is free to stream away unhindered to the point of disposal.
Although 80mm and 100mm are the sizes for national applications these pipes’ diameter varies from 60mm to 150mm. Although coils are available in some of the sizes coil lengths are generally 25m or 50m. Where is a need for strength in the drain pipe, a rigid perforated Twinwall pipe should be used instead of the coiled alternative. Examples of this would be where the pipe is buried deep down and thus the backfill material over the pipe is particularly heavy.
