  • Type of subsoil drainage

    The most popular type of subsoil drainage system is in the form of a special pipe which is covered with geotextile material. The pipe has a number of perforations through it, allowing the water entering to be drained away. The geotextile covering is important as it prevents soil and other particles from running through the pipe and potentially clogging it up.

    If you think you need subsoil drainage in your property, you may be wondering exactly where it should go. If you have a retaining wall, it is essential that you have subsoil drainage behind it, thus relieving the pressure of water on it. It is also recommended to have subsoil drainage systems in raised garden beds.

    Subsoil drainage should be installed in low areas of your garden preventing water from damming up and stagnating. Subsoil drainage should also be installed around the perimeter of your property, allowing water to be drained away preventing it from destabilising your foundations. It is paramount that the subsoil drainage systems are located above the natural water table, otherwise you will be draining away ground water and not that of surface water.

    To ensure that your home and garden is free from risk of water damage, it is essential that you have a form of drainage installed. An effective but unobtrusive method of drainage is the use of a subsoil drainage system.

    A subsoil drainage system is designed to be installed within the ground itself, thus allowing excessive water to be removed from the soil. This prevents damage to properties and landscapes. Because the drainage system is buried beneath the soil, it is advisable that the drainage system is planned during the landscaping or building stage. However, a subsoil drainage system can be installed following the building stage, should it not have been taken into account sooner.
