What is Subsoil Drainage?

Subsoil drainage is an underground water-management solution designed to control excess groundwater that collects beneath the surface, particularly in clay-heavy or low-lying landscapes. By installing perforated pipes surrounded by filtered drainage gravel, the system lowers the water table and relieves soil saturation that surface drains cannot address. This ​prevents root damage, lawn sponginess, erosion, and pressure against building foundations. Engineered with precise gradients and integrated discharge points, subsoil drainage works invisibly below ground to keep your landscape firm, healthy, and usable year-round.
