Retaining Wall Drainage

Retaining wall drainage is a crucial process in the construction of retaining walls, designed to prevent water buildup behind the wall, which can cause hydrostatic pressure and lead to wall failure. This technique involves installing drainage systems such as weep holes, perforated pipes, and gravel backfill to facilitate the movement of water away from the wall structure. Proper drainage ensures the longevity and stability of the retaining wall by reducing the pressure exerted on it by trapped water. The design and installation of retaining wall drainage must be carefully planned to account for the type of soil, the wall’s height, and the amount of expected water runoff.
