Concrete retaining walls in Castro Valley CA - drained so your slope stays put
Is hillside soil sliding into your yard, or is an old wall starting to lean? We pour a drained concrete wall that holds the ground.
Do I need a new retaining wall, or can mine be saved?
A concrete retaining wall takes the sideways push of the soil behind it, so the ground above and below it stays where it is. In Castro Valley we pour these walls with the drainage built in from the first day of work.
Most calls start with one of two things. Either a slope keeps creeping into a yard or driveway, or an old wall has started to lean or crack. The price moves with the wall's size and shape, with whether an old wall has to come out first, and with how much digging the slope needs. The schedule depends on the design, on any review the county does, and on curing, which is the wait while the concrete gains strength before soil goes back against it. When I come out, the estimate spells out what's included, so you can see what you're paying for before you decide.

Retaining walls, slabs and pool decks
How we build a concrete retaining wall
I start by looking at the slope, at what sits above and below it, and at how you want to use the ground, because that sets the plan before anyone digs. Our crew digs out for the footing, which is the wide base the wall stands on. We set rebar, the steel that keeps the concrete from cracking apart when the soil pushes, and then we form and pour. Behind the wall we build in the drainage that drainage guides call for. That means clean crushed stone, filter fabric, a perforated pipe and a clear outlet or weep holes, which are small openings that let water out. Each of those is its own line in the quote, so you can see it's there. We let the concrete cure before the backfill goes in, and then we clean up. If the budget gets tight, I'd rather simplify the face of the wall than cut the drainage or the footing. Nobody sees those once the job is done, but they're what keep the wall standing.
A wall often makes room for the next project. When it cuts a flat pad out of a slope, that pad can take a concrete floor for a shed or workshop. If the flat ground is for a pool, we plan the wall and the pool deck together, so the deck's runoff doesn't end up soaking the soil behind the wall.

Retaining wall questions from Castro Valley
What does a concrete retaining wall cost near Castro Valley?
In Alameda County, a basic poured concrete retaining wall about 3 feet high usually costs about $47 to $52 per square foot to install. That's the going rate in the area, not our price. It doesn't cover tearing out an old wall, extra height, curves, terraced walls or stamped and stained finishes, and any of those costs more. When you compare quotes, ask each contractor whether their number covers site prep, digging, filter fabric, concrete, gravel backfill and steel.
Will adding drainage fix my leaning retaining wall?
No. Once a wall has leaned or cracked, it has already moved, and drainage behind it won't pull it back. A wall like that usually needs rebuilding from the base, with drainage built in from the start. If yours is past saving, I'll tell you so plainly when I look at it.
What decides how big and strong a retaining wall needs to be?
Height alone doesn't decide it. The footing, the steel, the drainage and the soil assumptions should come from a design for your site or from the code that applies, because the wall may also have to handle groundwater, a slope above it, earthquakes and the weight of cars or a building nearby. That design only holds if the site stays the way it was planned. Changing the soil behind the wall, adding a driveway next to it or letting water build up later can undo it.
Which office handles retaining wall permits in Castro Valley?
Alameda County handles building permits for Castro Valley through the county's permit portal, and the county also issues encroachment permits for work in county roads, sidewalks and public right-of-way. Projects sent to the county's grading staff are checked against county rules, including how they reduce flood, earthquake and fault hazards. That's one more reason each wall here needs a design that fits its site. We check with the county early, and when your wall needs a permit, we handle the application and set up the inspections.
How do I take care of a retaining wall after it's built?
After a heavy rain, check that water is coming out of the outlet pipe or weep holes, and keep leaves, mulch and soil cleared away from the base of the wall. Point your downspouts away from it. Give us a call if you see new staining, cracking, leaning or soft ground near the wall.
How long does it take to build a concrete retaining wall?
Most of the schedule comes down to three things: the design, any county permit review, and the curing wait before soil goes back behind the wall. How much digging your slope needs matters too. When I put your job on the schedule, I'll lay out the order of work, so you know what happens when before anyone shows up.
