Yes — every retaining wall in Dallas needs drainage. Dallas County sits on expansive clay soil that holds water and creates hydrostatic pressure behind walls. A 4-inch perforated pipe wrapped in filter fabric, set in 12 inches of gravel backfill, is the DFW standard. Skipping drainage is the #1 cause of retaining wall failure in the DFW area and is not covered by most contractor warranties.
