A retaining wall has one job: keep soil where it is, against the force of gravity, water, and time. Most failed retaining walls fail for the same two reasons — no drainage and no engineering for the actual lateral load. We build retaining walls that respect both: drainage gravel and weep holes behind every wall over 3 feet, structural reinforcement designed to actual surcharge loads, and footings sized for the soil bearing capacity at your specific site.
Concrete retaining walls offer the strongest load capacity and the longest service life of any common retaining option. Done right they last 50+ years. Done wrong they bulge, lean, and eventually fail catastrophically, usually after a heavy winter that saturates the back-fill. The difference is the drainage detail and the footing design — neither of which is visible after backfill, but both of which determine whether you've built a wall or a future emergency.
We build poured-in-place retaining walls, with engineered footings, vertical and horizontal reinforcement to drawings, drainage gravel and perforated pipe at the base, weep holes through the face, and a water-side membrane on walls over 4 feet. For walls above 4 feet in height, an engineer-stamped design is required by code in California — we work with structural engineers across the metro to deliver that.
