Properly Drained Retaining Walls in Danville, Orinda, Lafayette & Nearby Communities
Everything we build here runs from footing to backfill: poured concrete walls, block walls and tiered terraces, each with drain rock, pipe and weep provision.
Homeowners on sloped lots usually call about one of three things: soil creeping down onto a patio, a failing railroad-tie wall from the eighties, or a flat pad they want carved out of a hillside.
All three come down to the same engineering question. How much soil is pushing, and where does the water go?
A retaining wall fails from water pressure far more often than from weight. Drainage behind the wall matters as much as the concrete in it.
Every wall we build gets a proper footing, a reinforcement schedule, backfill drainage and weep provision. Walls retaining more than about four feet need engineered plans and a permit, and we handle that filing.

Retaining Wall Questions We Get Weekly
Do I need a permit for a retaining wall?
Generally yes once the wall retains more than about four feet of soil measured from the bottom of the footing, and sooner if it carries a surcharge such as a driveway above it. We confirm the threshold with your city and file the permit.
Why do retaining walls fail?
Water, almost always. Saturated soil behind a wall pushes far harder than dry soil does. Walls built without drain rock, pipe and weep provision bow and crack no matter how thick the concrete is.
Concrete or block for a retaining wall?
Poured concrete handles the most height and load and gives you a continuous structure. Block is a practical, lower-cost option for shorter garden and grade walls. Height and what sits above the wall drive the choice.
Can you replace an old timber wall?
Yes, and it is a common job on older Contra Costa lots. Timber walls from the seventies and eighties are usually at the end of their service life. We remove the old wall, re-cut the bench and pour a properly drained replacement.
How long does a retaining wall take?
A short garden wall can be finished in under a week. Engineered walls that need plans, permits and inspections run longer, and the approval timeline is usually the biggest variable.
How much does a retaining wall cost?
Cost tracks height, length, engineering and site access, so a per-foot number quoted sight-unseen is not worth much. We measure the slope and give you a firm written bid.
