Land drain pipes are pipes that allow water to enter through small perforations. The water then flows away to a suitable disposal point like a stream, a storm drain or a soakaway. You should check to confirm that your chosen point of outfall is permissible. Land Drains should never be attached without the permission of the Local Authority to a foul or joint drain, and in such situations the relationship must incorporate a snare.
In waterlogged areas, carefully packed soil particles hold the water in position — there’s not any escape route for the water. By replacing the majority of these dirt particles a route to the water to travel through is generated, since the gap between each piece of shingle is greater than the gaps between the soil particles. Gravity takes hold and the water then picks up speed, channelling downwards and into the land drain itself through the perforations in the pipe. Once inside the pipe, which is placed in a gentle gradient, the water is then free to stream away unhindered into the point of disposal.
Unlike underground ducting where colour is an indicator of what is inside the duct, colour is irrelevant when it comes to land drains.
Although 80mm and 100mm are the most popular sizes for national applications, these pipes’ diameter varies from 60mm to 150mm. Although 100m coils can be found in some of the sizes, coil lengths are usually 25m or 50m. A perforated Twinwall pipe ought to be used rather than the coiled option where there’s a need for strength in the pipe. Examples of this would be in cases such as under a driveway or in which the pipe is buried deep down and hence the material over the pipe is very heavy.
