Serving Yakima, WA and surrounding areas. (509) 654-9682
Yakima slopes, clay soils, and hard winters demand walls that are built right from the footing up. We design and build concrete block walls that hold their ground for decades.
Concrete block walls in Yakima, WA are built by pouring a concrete footing below the frost line, stacking mortar-set block rows in an overlapping pattern, and - for retaining walls - installing drainage gravel behind the wall as construction goes up, with most residential projects completed in one to three days.
Concrete block walls serve a range of purposes: retaining a slope and stopping erosion, creating a defined boundary between properties, edging a driveway or patio, or building a raised garden area. What they all have in common is that a wall that fails or leans within a few years almost always traces back to one of two problems - a footing that was not deep enough to handle Yakima's freeze-thaw cycles, or drainage that was not installed behind a retaining wall to relieve clay-soil pressure.
If your property has a slope that needs to be held back, our retaining wall construction service covers the full range of retaining applications, including walls that require engineering review for taller installations.
If you see bare patches where grass used to grow or small gullies forming after spring rain, your slope needs to be held back. A concrete block retaining wall stops that erosion and turns an unstable hillside into usable, level yard space. Yakima properties near the bench areas east and west of downtown often have significant grade changes that make parts of the yard unusable without a wall.
If a wall is visibly tilting away from the soil it holds, or you notice wide cracks running through the blocks or mortar joints, the wall is under stress it was not designed to handle. In Yakima, this often happens to older walls built without adequate drainage - clay soil holds water, pressure builds, and the wall slowly gives way. Catching this early is far less expensive than dealing with a full collapse.
If the edge of a driveway or patio is cracking because there is nothing holding the soil beside it in place, a low block wall along that edge stops the damage from spreading. This is common in Yakima neighborhoods where properties have been landscaped over the years without proper edging structures.
If you have been avoiding a section of your yard because it is too steep to mow, plant, or walk on safely, a terraced block wall system can level it out and give you back that space. A well-placed wall does not just hold soil - it creates a defined, usable outdoor area where there was only awkward slope before.
Every wall we build starts below grade. We dig down past the frost line - at least 12 to 18 inches in Yakima depending on the site - and pour a concrete footing before the first block is set. That base is what keeps your wall from shifting when the ground freezes and thaws over Yakima winters, and skipping or shortcutting it is the most common reason block walls fail within a few years. For retaining walls, we also install drainage gravel and, where the site requires it, a perforated pipe behind the wall as we build - so water moves through the wall system rather than building up pressure against it. If a retaining wall project calls for it, we can also apply foundation block wall techniques for walls that need to carry more structural load.
Block walls also make an ideal substrate for stone veneer if you want the wall to look like natural stone rather than bare concrete. We can handle both the block construction and the veneer application as one project. For properties that already have a retaining wall showing signs of distress, our retaining wall construction service covers repair and full replacement on walls that have begun to lean, crack, or separate.
Best for properties with slopes, grade changes, or erosion problems where the wall needs to hold back soil pressure and channel water away from the structure.
Best for homeowners who want to define a raised garden bed, a planting area, or a tiered landscaping feature at a lower height that may not require a permit.
Best for creating a durable, low-maintenance boundary between your yard and a neighbor's property, with no painting or sealing required the way a wood fence does.
Best for properties where the edge of a paved surface is crumbling or shifting because there is no solid structure holding the adjacent soil in place.
Two local conditions drive most of the concrete block wall failures we see in Yakima: freeze-thaw cycles and clay soil. Yakima winters bring repeated hard freezes, and the ground can freeze several inches deep from November through March. Any footing that does not reach below that depth will shift as the soil expands and contracts - and a wall that shifts will crack. That is why we always dig down past the frost line, even on lower walls where it adds time and cost to the job. Homeowners in Moxee and surrounding areas with agricultural backgrounds often have older block walls built before this standard was widely followed, and those walls are the ones we see leaning or separating today.
Clay-heavy soil is the second factor. Much of the Yakima Valley has soil that holds water rather than draining it away. When that soil gets saturated from spring snowmelt or irrigation, it expands and pushes outward with real force. A retaining wall that was not built with drainage gravel behind it will eventually lose that battle. We install drainage on every retaining wall we build - it is not an upgrade, it is part of the job. Homeowners in Terrace Heights with elevated lots and hillside landscaping see this issue clearly: the slopes look manageable until a wet spring puts real pressure on an old wall. Before any digging begins, we also call Washington 811 to have underground utility lines marked - Yakima properties often have irrigation lines close to the surface, and we do not assume a yard is clear.
When you reach out, we want to see the site before giving you a number - a description rarely tells the whole story. We reply within one business day to schedule a visit. During the visit we look at the slope, soil, access, and what the wall needs to do, and we ask about your goals and budget.
After the site visit we prepare a written estimate that breaks down the work and the cost. If your wall is tall enough to require a City of Yakima permit, we let you know and handle the application. Permit approval typically takes one to three weeks, so this is the time to get that process started.
We call 811 to have underground utilities marked, then excavate below the frost line and pour the concrete footing. This is the most important part of the job - what keeps the wall straight through Yakima winters. The footing needs time to cure before block-laying begins.
We build the wall row by row, installing drainage material behind retaining walls as we go. Once complete, we clean up the site and walk the finished wall with you before we leave. The mortar needs about 28 days to reach full strength, so we advise against heavy backfilling or loading the wall immediately.
No obligation. We come to your property, assess the site, and give you a written estimate before any work is scheduled.
(509) 654-9682We dig below the frost line on every wall we build in Yakima - no exceptions. This adds time and cost compared to a shallow base, but it is what keeps your wall from cracking and leaning after the first hard winter. Contractors who skip this step are not saving you money; they are pushing future repair costs onto you.
Yakima's clay-heavy soils hold water and push with real force when saturated. We install drainage gravel and, where the site requires it, a perforated pipe behind every retaining wall. That drainage system is what separates a wall that lasts 50 years from one that fails in five - and it is included in our standard build, not an add-on.
Retaining walls over four feet in Yakima require a building permit, and we handle the City of Yakima application and inspection coordination for you. That paperwork protects you: a permitted wall has a documented record that matters if you sell your home or make a future insurance claim involving the wall.
You can verify our contractor registration with the Washington State Department of Labor and Industries before signing anything - just search by company name. Registration means we are bonded and insured, which protects you if anything goes wrong during the project. We follow standards set by the{' '} National Concrete Masonry Association on footing depth, drainage, and mortar specifications.
These commitments come together in one guarantee: the wall we build stays where we put it. We follow construction standards published by the National Concrete Masonry Association on footing depth, drainage, and mortar specifications, and every project includes a written estimate so the price you agree to is the price you pay.
When your block wall needs to carry structural load rather than just retain soil, our foundation block wall work covers the engineering and build.
