Concrete retaining walls in Fontana CA - a wall that holds back soil and lets water out
Is soil sliding onto your patio or washing off a slope? We build poured concrete walls, drained behind, that keep the ground where it belongs.

Do you need a concrete retaining wall for your Fontana yard?
A concrete retaining wall is a poured wall, with a footing under it and steel inside, that holds back the soil behind it, called backfill, so a slope in your Fontana yard stays put and the ground in front of it stays usable.
Most wall calls start with a slope creeping onto a patio or a yard that's more hill than flat ground. A wall lets you cut that slope back into level space, whether that's room for concrete pool decks or a pad for a workshop and its concrete floor installation. The job is digging out for the footing, setting steel, forming and pouring the wall, then laying drainage and putting the dirt back behind it.
The price moves with the wall's height and length, how deep the footing has to go, how much steel and drainage the design calls for, and whether we can get equipment in. What sits above the wall matters just as much, because a driveway or a building adds weight the wall has to hold. The schedule usually turns on the design, any permit and the inspections more than on the pour, and your written estimate spells out what's included.
What makes a concrete retaining wall hold
Most of a retaining wall's strength is in parts you won't see once the dirt goes back, so these are the choices worth settling before we dig.
Poured wall or block wall
A poured wall is formed and filled in place with concrete and steel, while a segmental block wall stacks concrete units without mortar and holds mostly by its own weight.
Sized for what sits near it
We don't size a wall by its height alone, so before anything gets designed we talk through the driveway, building or lot line near it and any grade change you're planning.
Footing and steel
The footing is the wide base the wall stands on, and rebar, the steel inside, holds the wall together against the dirt's push. Their size comes from a design or the code.
Drainage behind the wall
Gravel, a filter fabric and a perforated drain behind the wall let water out before it piles pressure on the concrete. On a tight budget, cut the face finish, not this.
Retaining wall questions we hear in Fontana
How much does a concrete retaining wall cost in Fontana?
Poured concrete retaining walls in the San Bernardino area usually cost about $35 to $45 per square foot of wall face, which is the part you see, measured by length and height. Where yours lands depends on how much digging the footing needs, how much steel and drainage the design calls for, and what sits above the wall. Our own price comes in a written estimate after I've seen the site, and the work is backed by our satisfaction guarantee.
Do I need a permit for a retaining wall in Fontana?
The city requires a building permit for solid fences or walls exceeding 42 inches in height, and Fontana Building & Safety is the office to ask about how that applies to your wall. When your wall needs a permit, we pull it under our license and work with the city ourselves, so you won't be the one filling out the application.
Why does a retaining wall need drainage behind it?
Water that builds up behind a wall can greatly raise the load on it and cause leaks, so drainage belongs in every quote you compare. A sound wall has drain rock, a filter, perforated drain outlets, weep holes where the design shows them, which are small openings that let water through, and surface drainage so runoff doesn't pour over the top. Those outlets need to stay clear and working over the years, so I'll show you where they come out.
Can a retaining wall go on the property line in Fontana?
It can, but not under Fontana's standard retaining wall plan, which can't be used on or next to a property line and isn't built to carry loads from vehicles or other structures. A wall right on the line also needs your neighbor's authorization, so it's worth talking to them early, and you can check what the city asks for on its building permits page. The city's draft hazard plan also flags earthquake liquefaction along the Lytle Creek corridor and landslide potential at its mountain-front edges, so if your lot sits near either, we'll talk about it before anything gets drawn.
How long does it take to build a concrete retaining wall in Fontana?
The schedule usually depends more on the design, any permit and the inspections than on the day we pour. On a block wall built to the city's standard plan, an inspector checks the footing trench with steel in place, the block and steel before grouting, the grouted wall and drainage before backfill, and a final once the cap and cleanup are done. The concrete also needs curing, the wait while it gains strength, before we push dirt against it, and I'll walk you through that order when I come out.
How do I choose a contractor for a retaining wall in California?
Start by checking for a California contractor license, since the state contractor board licenses concrete contractors to form, pour, place and finish concrete work, and its masonry license exam covers building and repairing retaining walls. On home improvement work, a contractor can't take a down payment over $1,000 or 10 percent of the contract price, whichever is less, and later payments should be listed in the contract and tied to work done or materials delivered. Then compare quotes that include the same footing and drainage, because the cheapest wall is often the one missing what's underground.
