In really heavy clay soil, consider skipping land drainage altogether and just having runs of stone-filled trenches instead. The pipes are drilled whilst wet and the semi-dry nature of the concrete used in the manufacturing process leads to spalling on the inner and outer surfaces around the holes. The pipe should be surrounded by gravel in a trench where water moves through the ground, passes through the gaps in the gravel, and starts to fill the trench surrounding the pipe.

Twin extrusion process means pipe is strong with a corrugated outer wall and smooth inner wall, assisting hydraulic flow. Perforated land drain is used to collect water through the small holes located around the pipe; these holes allow water to seep from the ground into the pipe and be carried away or to percolate back into the soil at a practical rate.

A Guide to Perforated Drain Pipes | Drainfast Ltd

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. Levelling the soil properly will ensure your perforated pipe installation lasts and works properly for many years to come. You can also find geotextile filter wrap - a sort of sock that fits around the flexible land drain pipe. A French drain is simply a small trench, dug to a gradient, and filled with aggregate, that will allow surface water to drain away from your walls, a building, driveway, garden or area that is prone to surface water pooling, or is vulnerable to flash flooding. If the pipe is placed upside down, with perforations towards the top of the pipe, it's not like it wouldn't work — the pipe performs better and transports water quicker if they are pointing down.However a French drain may not solve the problem of damp totally and other means of controlling the water may need to be found in addition to the drain i. They are mainly installed as a part of underground drainage systems and for outdoor uses to facilitate easy drainage and thereby prevent flooding on site.
