” the answer is a resounding yes. Drainage systems are not just beneficial but necessary for maintaining the structural integrity of retaining walls. Whether it is surface drainage or subsurface drainage, the installation of a well-planned and properly executed drainage system is essential to prevent water buildup, hydrostatic pressure, and potential damage to the retaining wall. By considering factors such as design, material selection, placement, and maintenance, a drainage system can effectively work hand-in-hand with a retaining wall, ensuring its stability and longevity for years to come.
