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

Product Information

In really heavy clay soil, consider skipping land drainage altogether and just having runs of stone-filled trenches instead. What gravel should I use with land drainage? You will need gravel in the trenches to replace the soil you remove; a pea shingle gravel no larger than 40mm is recommended. In the ground water takes the path of least resistance, and in heavy clay-type soil, stone is much easier to flow through. Water is attracted to the trenches and seeps through into the land drainage system.

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. If the foundations of the building are very shallow then the French drain should be constructed at a minimum of 1 meter away from the building. Browse our range of perforated land drainage pipes in sizes from 60 to 100mm. These perforated land drainage pipes are suitable for use as a collector drain for the removal of excess surface water from both gardens and fields to a suitable collection point. For this type of twinwall, standard orange 110mm drainage fittings and junctionsare used to create a system.

French Drain Cleaning And Maintenance

For 80mm land drain the trench width would be 380mm (2 x 150mm + 80mm pipe) and height 630mm (100mm base + 80mm pipe + 300mm drainage layer + 150mm top soil). Draining Water from Under a House: When the weather gets bad and there is a huge amount of rainfall, your property can suffer with an overflow of rainwater. However, this excess of water does not need to drown your lawn or start flooding your property. You can avoid these serious problems with the help of a perforated drain pipe. Having a perforated pipe underneath your property will help drain excess water away from your home, leaving the area dry and avoiding costly problems like rot and water damage. Mostly, upward-facing perforation helps keep silt and debris from accumulating in the pipe during water collection. At the same time, pipes with perforations facing down help faster collection and distribution. The type of perforation is selected based on the application.

French Drain detail showing a cross section showing the graded stones and a perforated drainage pipe It is a relatively simple and cost effective way of draining land, and it does not require specialist tools or complicated equipment. Perforated pipes are an efficient solution to drain flooded yards, fields, and wet basements. They are designed and manufactured to be more flexible as they are always buried underground for a longer period. Although you would think that having the holes at the top would mean the water could fall into the perforations, as it flows through the ground, this doesn't offer the best performance.

Will A French Drain Solve A Damp Problem?

You don't need an in-depth technical construction drawing but making a plan of what, where and how will make a handy guide throughout installation. A perforated drain pipe is one of the most essential aspects of your drainage system. Perforated drain pipes provide drainage solutions to excessive standing water near the building foundations of your domestic or commercial property.

Should pipe perforations go up, or down? | JDP

A French drain should be no deeper than the foundations of a building and, in the case of older buildings, the side of the trench should slope away from the building at no less than 45 degrees. This is to maintain the lateral support of the foundations by the ground surrounding them. Perforated pipes are installed around residential buildings to prevent yards from flooding during heavy rains. The perforated pipes used for this purpose have a smaller diameter of 5 inches. Typically, land drainage is arranged in a herringbone style with one central pipe and several branches coming out of this; this ensures the area is drained efficiently and maximises the effectiveness of the land drain pipes. How to lay land drainage? Contrary to popular opinion, the most effective method is to have the holes facing down. Why do the perforations go downwards?On entering the trench the water will have to run to a suitable drain–off point, and in most cases this is a soakaway or watercourse. A French drain is not intended to replace existing surface water drains. However French drains are useful where water tends to build up against walls and buildings. Most of the grassy areas are converted into playgrounds, so they are more prone to flooding. The problem is solved by installing a large underground perforated pipe to filter the water away. 3. Perforated Pipes for Irrigation Perforated pipes are installed to collect excess water from the soil and drain it directly down to the roots of plants or crops—this helps to keep the irrigation land healthy without flooding the field.
