Serving Chino Hills, CA and surrounding areas. (909) 729-4539
Your hillside is shifting and your yard is shrinking. We build reinforced concrete retaining walls that hold your slope in place - with proper drainage built in so the wall stays solid through every wet season.
Concrete retaining walls in Chino Hills hold back soil on sloped or graded lots, most projects take two to five days from excavation to backfill, and the finished wall can last 50 years or more when drainage and reinforcement are done right.
Chino Hills was built on rolling terrain, and many properties sit on graded hillside lots where the original slope was cut to create a flat yard. Over time - especially after wet winters - that cut-and-fill soil starts to move. A properly engineered concrete retaining wall stops that movement and turns an unstable slope into usable outdoor space. If you are also thinking about what that new flat area could become, concrete patio construction is a natural next step.
Unlike timber or block walls, a poured concrete wall handles the wet-dry stress cycles that Chino Hills clay soil produces every year. It does not rot, it does not tip individual blocks, and when it is built with a drainage system behind it, hydrostatic pressure from winter rain has somewhere to go instead of pushing your wall outward.
If you notice soil slowly moving downhill - pushing against a fence, piling up near your foundation, or leaving bare patches higher on the slope - that is a sign the hillside is not stable. In Chino Hills, where many lots were graded on clay-heavy soil, this kind of slow movement is common and tends to get worse after wet winters. A retaining wall stops the movement before it reaches your home.
A wall that tilts forward, shows horizontal cracks near the middle, or has gaps opening up between the wall and the ground behind it is under stress it was not designed to handle. These are warning signs that the wall may be close to failing - and a failed retaining wall can dump a significant amount of soil into your yard very quickly. Do not wait to have it evaluated.
If standing water collects at the bottom of a hillside on your property after Chino Hills winter rains, water is running down the slope rather than draining away properly. Over time, that water saturates the soil, adds weight, and increases the pressure on whatever is holding the slope in place. A retaining wall with drainage built in solves both problems at once.
If you want to create a flat area on a sloped Chino Hills lot - for a patio, a garden, or a play area - a retaining wall is almost always part of how that gets done. The wall holds back the uphill soil so the flat area stays level and stable. Without it, any fill you add will eventually shift.
Every retaining wall project starts with a site visit to understand how water moves across your property and what the soil conditions look like. From there we design the wall height, footing depth, and drainage layout for your specific lot - not a generic plan pulled from a different city. Whether you need a short garden wall to terrace a planting bed or a taller structural wall to protect your foundation, we build to local permit standards and use steel-reinforced concrete that handles the expansion and contraction Chino Hills clay soil puts on structures every year. Homeowners who want the wall to double as a visual feature sometimes pair this project with concrete steps construction to connect tiered levels cleanly.
We handle permits with the City of Chino Hills Building and Safety Division, coordinate required inspections, and include drainage installation in every wall we build. The gravel backfill and perforated pipe behind the wall are not an add-on - they are part of the structure, because a wall without drainage is a wall that will fail in this climate. If you are also working on the outdoor living area around the wall, take a look at our concrete floor installation service for patios, pathways, and covered areas.
Best for homeowners managing active soil movement, protecting a foundation, or creating a significant level change on a hillside lot.
Suited for terracing sloped yards, creating raised planting beds, or adding definition to outdoor spaces without major excavation.
Ideal when an existing timber, block, or aging concrete wall is leaning, cracking, or no longer holding the slope as it should.
The right approach for steep lots where a single tall wall would require excessive excavation - multiple shorter walls step down the slope more efficiently.
Chino Hills sits on clay-heavy soil that swells when it rains and shrinks when summer heat dries everything out. That wet-dry cycle happens every year, and over time it puts more cumulative stress on retaining walls than flat, sandy ground would. The city was also developed on graded hillside terrain, which means a large share of homes have sloped lots where cut-and-fill soil is already prone to movement. The Portland Cement Association recommends specific drainage and footing standards for walls in expansive soil conditions exactly like what we see throughout this city. Homeowners in Chino Hills dealing with slope problems should act before the next rainy season adds more pressure to an already-moving hillside.
The City of Chino Hills enforces its own building permit and grading requirements for retaining walls above a certain height, and many neighborhoods here are governed by HOAs that add another layer of pre-approval before structural work can begin. That combination of city permits and HOA rules is something a contractor who has never worked in Chino Hills may not anticipate - and missing either one can stall a project or create problems at resale. Homeowners in neighboring Diamond Bar face similar hillside and HOA conditions, and we work across both communities regularly.
We walk your property in person to look at the slope, soil, drainage, and what is nearby before giving you any numbers. You will have a written estimate that breaks down the cost and explains what is included - usually within one business day of the visit.
We handle the permit application with the City of Chino Hills and confirm whether your HOA requires pre-approval before work begins. Permit processing typically takes one to three weeks, and we factor that into the schedule so there are no surprises.
The crew digs down to create a stable footing below the frost line and utility depth. This underground work is the most important part of the whole job, even though you will never see it once the wall is finished. Most residential excavations take one day.
We build the form, place the steel reinforcement, pour the concrete, and install the gravel-and-pipe drainage layer behind the wall in the same phase. After the pour, the concrete cures before backfill - we will tell you exactly when the area is safe to use again.

(909) 729-4539Every retaining wall we build includes a gravel backfill layer and a perforated drain pipe behind the wall. This is not optional - it is how we build. Hydrostatic pressure from Chino Hills winter rains is the top cause of early wall failure, and our walls are designed to handle it.
We handle the building permit with the City of Chino Hills and coordinate required inspections from start to finish. An inspected, permitted wall is documented and clean at resale - an unpermitted wall can kill a sale or require expensive remediation.
We size footings and reinforcement for the clay-heavy soil conditions specific to Chino Hills, not a generic standard from a flat-lot project. The American Concrete Institute publishes guidance on designing for expansive soils, and our approach follows that framework.
A large share of Chino Hills neighborhoods are HOA-governed, and many require written approval before structural work begins. We ask about HOA requirements at the estimate visit and can help you prepare the approval request so your project is not delayed by a step your contractor did not anticipate.
A retaining wall that stands for decades is the result of getting the drainage, footing, and reinforcement right the first time. Those details are built into how we work on every project in Chino Hills.
Once the wall holds the slope, add a durable concrete surface to the new flat area for a patio, pathway, or covered space.
