These systems use subsoil drainage pipes, underground pipe and drainage pipe types chosen for your soil type, slope and the amount of water to remove.

The Clean Plumber’s qualified team inspects the affected area, tests drainage and water table, then recommends a cost-effective solution, from a simple drainage pipe and gravel trench, to mole drainage or a pumped system. We aim for minimal disruption, protect your soil and plants and maintain structural integrity.
