Foundation movement shows up as stair-step cracks, sticking doors, or a sloped floor, and delaying repairs can turn small gaps into structural problems. Since 2018, Quality Concrete Washington has delivered concrete foundation repair for homeowners and commercial buildings in Washington, focusing on correct diagnosis and permanent stabilization.
We start with an on-site evaluation of the foundation wall and footing, measuring crack width, mapping displacement, and checking drainage, downspouts, and grade. Prep typically includes sawcutting and removing loose concrete, cleaning to sound substrate, and setting access for equipment like rotary hammers, grinders, and HEPA vacs. When needed, we stabilize soils and bearing surfaces with compacted crushed stone (often #57), controlled low-strength material (CLSM), or engineered fill, then verify elevations before any structural patching or underpinning begins.
For repair work, we match the method to the failure mode: epoxy injection for structural cracks, polyurethane injection for active water intrusion, carbon fiber straps or wall anchors for bowing walls, and reinforced concrete patching where section loss is present. If settlement is ongoing, we coordinate underpinning solutions such as helical piers, push piers, or concrete underpinning pads tied into the footing with drilled dowels and epoxy adhesive. All concrete work is placed with proper steel reinforcement, consolidation, and curing practices, then finished for the space, from smooth trowel in basements to parge coats on exposed walls, with waterproofing options like cementitious coatings or membrane systems when appropriate.
Washington customers choose us because we do not guess, we document conditions and explain what is cosmetic versus structural. You get clear scopes, material specs, and repair sequencing that respects the building, including protection of utilities, interior finishes, and adjacent slabs. Our crews use proven products, proper surface prep, and the right tools for confined foundation areas, and we keep the job moving with organized staging, debris control, and straightforward communication from start to final cure.
At closeout, we walk you through every repaired area, review crack locations, reinforcement, injection ports, and any waterproofing or drainage improvements. We confirm cleanup, patch edges, and transitions, then provide a written summary of work performed and maintenance guidance, including drainage and gutter recommendations that help prevent repeat movement. If your project includes piers or underpinning, we also document pier locations and final elevations so you have a record for future renovations or property files.
Yes. We break and remove existing slabs, dispose of debris, then re-grade and rebuild the base before pouring new concrete. Demo scope is listed in the written estimate.
Some projects may require permits or inspection depending on scope and location. We can explain typical requirements and coordinate sequencing so inspections do not delay the pour.
We can match common finishes such as broom-finish, smooth trowel, exposed aggregate, and light texture, and we can align joint patterns where feasible. Exact color matching is never guaranteed due to batch variation and curing conditions.
Common causes include inadequate base compaction, poor drainage, missing or shallow control joints, overwatering, finishing while bleed water is present, and improper curing. We manage these factors during prep, placement, and cure.
When the base is stable and damage is localized, repairs like partial replacement, edge rebuilds, patching, or grinding trip hazards can make sense. If the slab is heaved, severely settled, or widely spalled, replacement is usually the durable option.
Concrete foundation repair is not one product or one quick patch, it is a process of identifying why the foundation moved and selecting the right correction for cracking, bowing, or settlement. Quality Concrete Washington repairs residential and commercial foundations by combining detailed evaluation with proven materials like epoxy and polyurethane injection systems, reinforced concrete patching, and stabilization methods such as helical piers or underpinning when needed. The goal is simple: restore structural performance, reduce water intrusion, and protect the value of the building.
Common signs you may need concrete foundation repair include horizontal cracks in foundation walls, stair-step cracking in masonry above, widening vertical cracks, uneven floors, and water staining after storms. The right repair depends on cause and location. Structural cracks are often addressed with epoxy injection to bond concrete back together, while wet cracks may call for polyurethane foam injection to seal and flex with minor movement. Where concrete has spalled or deteriorated, we remove unsound material, treat reinforcement when present, drill and epoxy-set dowels, then place high-strength repair mortar or concrete and cure it correctly to control shrinkage and achieve long-term bond.
If the foundation is moving due to settlement, patching alone is not enough. We can coordinate stabilization with helical or push piers, or reinforced concrete underpinning pads, tying new support into the existing footing so loads transfer properly. For basements and crawlspaces, we can also pair repairs with moisture control measures such as cementitious waterproof coatings, drainage improvements, and better grading so hydrostatic pressure does not keep working against the wall.
If you are seeing new cracking, sticking windows, or recurring leaks, schedule an on-site assessment. We will review conditions, explain the repair paths, and provide a free written estimate so you can choose a scope that fits the building and the budget without cutting corners.
Call now or send a request and we will reach out within one business day to schedule your free, no-obligation estimate in Washington. We assess the project, review the details, and give you a written quote before any work starts, so you know exactly what to expect.
