Large concrete slab repairs require homeowners to place considerable trust in the company entering their home. The work may involve exterior foundation stabilization, interior slab repair, or a carefully coordinated combination of services. Homeowners deserve a clear explanation of the problem, a repair plan based on the property’s actual needs, and a crew capable of completing that plan with precision.
At Oklahoma Foundation Solutions, our concrete slab services include two distinct engineer-approved processes: polyurethane injection for settled concrete and sub-slab voids, and floor stitching for qualifying structural cracks. The correct recommendation depends on what the home is experiencing.
Two Google Business Reviews show why the quality of the repair and the quality of the customer experience must remain connected throughout the project.
Making a Large Foundation Repair Project Feel Manageable
Ellie M. described a project that required help from the entire OFS team:
“I hired Oklahoma Foundation Solutions and am extremely pleased with the work that they did on my home. Everyone was extremely friendly, knowledgeable and professional. They worked quickly and left the property neat and tidy. From the OFS inspector, who provided the estimate, to the office staff who answered my many questions, and to the crew on site who worked on my property, OFS made having such a large job as pleasant an experience as possible! I am very pleased with their work.”

Ellie’s review follows the complete path of a foundation repair project. The inspector evaluated the home and prepared the estimate. The office staff answered her questions and helped coordinate the work. The crew then completed the project efficiently and treated the property with care.
A premium result includes each of those elements. Technical skill is essential, but so are communication, organization, preparation, and cleanup. When those standards remain consistent from the first appointment through the final inspection, even a large foundation project can feel orderly and manageable.
When Repair Estimates and Recommendations Vary Widely
Grant T. faced a different challenge. Several companies had evaluated his foundation, two structural engineers had reviewed the recommendations, and the proposed costs varied by tens of thousands of dollars.
He writes:
“We talked with several foundation companies who recommended a variety of solutions, hired two structural engineers to review the recommendations, had estimates ranging from $56,000 plus to $6,000 plus to fix the problems. When we contacted OFS, the inspector came out and reviewed the engineering reports and examined our home. After careful consideration, we decided to follow their recommendation.
They quickly scheduled our project, arrived on time and got to work at an impressive rate. Everything went as promised, and after placing exterior piers, they filled in the holes, and restored the ground to a degree that was amazing. You could not tell that any digging had occurred. Inside, their work was neat, clean and well done. Everyone who worked with us was professional and honest, and our foundation felt more stable. We are beyond happy with the job that they did, and the results that were achieved.”

A wide range of estimates makes the reasoning behind each proposed scope especially important. The American Concrete Institute explains that successful concrete repair begins with evaluating the existing condition and determining the cause. Those findings should guide the selection of repair methods and materials.
OFS reviewed Grant’s engineering reports, evaluated the home, and developed a coordinated recommendation. The exterior piers and interior work served different purposes within the overall plan. Once the work began, the crew followed the schedule, completed the repairs, restored the excavated areas, and left the interior clean.
Grant’s experience demonstrates the value of a properly prescribed repair carried out exactly as promised.
Why Oklahoma Concrete Slabs Require an Informed Evaluation
Oklahoma soil places unusual pressure on concrete slabs. According to the Oklahoma Geological Survey’s overview of geologic hazards, more than 75 percent of Oklahoma contains bedrock units capable of producing expansive soils. Clay-rich soils can expand as they absorb moisture and shrink as they dry.
Drainage problems, plumbing leaks, poor soil compaction, tree roots, and other property-specific conditions may also contribute to settlement. Because several causes can produce similar symptoms, a crack or uneven floor cannot prescribe its own repair.
The purpose of an evaluation is to determine what moved, why it moved, and which areas actually require stabilization.
Polyurethane Injection: Restoring Support Beneath Settled Concrete
When a concrete slab has settled or lost support because of underlying voids, OFS may recommend polyurethane concrete leveling and repair.
The process begins with careful preparation of the work area. Small holes, approximately 5/8 of an inch in diameter, are drilled through the concrete in a strategic pattern. Polyurethane is then injected beneath the slab. As the material expands, it fills voids between the concrete and the subgrade, restores support, and can gently lift the affected concrete.
Once the desired stabilization has been achieved, the injection holes are patched. Because the process uses small access points and does not ordinarily require widespread concrete removal, it is often less disruptive than replacement and can permit a faster return to use.
Precision is critical. The position of each injection point and the amount of material introduced beneath the slab influence the result. OFS’s HMI-certified team follows a controlled, engineer-approved process designed to provide lasting stabilization while minimizing disruption to the property.
Floor Stitching: Reinforcing a Structural Slab Crack
Polyurethane injection and floor stitching address different conditions. Polyurethane restores support beneath settled concrete. Floor stitching repairs qualifying cracks within an interior concrete slab.
For this process, the crew prepares the interior workspace and contains dust and debris. Approximately four to six inches of concrete are removed from each side of the affected crack. Rebar is then drilled and pinned into the existing slab with epoxy, connecting and reinforcing the separated sections. New concrete is placed over the repaired area to complete the reinforced connection.
Floor stitching is not appropriate for every concrete crack. Some cracks only require monitoring, while severe or widespread damage may call for partial or complete slab replacement. A thorough evaluation determines whether stitching is the appropriate solution and how much of the slab requires attention.
What Five-Star Concrete Slab Work Looks Like
OFS has earned hundreds of five-star reviews from customers across Oklahoma, along with Elite Service recognition from Angi and HomeAdvisor. The company’s current Better Business Bureau profile lists OFS as accredited with an A+ rating.
Those recognitions tell part of the story. Reviews such as Ellie’s and Grant’s explain what the standards look like inside an actual project:
- Inspectors who carefully evaluate the property and explain the recommendation
- Office staff who remain accessible and answer questions
- Experienced crews who arrive prepared and follow documented processes
- Precise work that respects the home
- A thorough inspection and cleanup at the end of the project
- Applicable warranty information provided in writing
OFS also stands behind qualifying repairs according to its written warranty terms. Customer satisfaction continues after the crew leaves because lasting value includes accountability and responsive follow-through.
Concrete Slab Repair Questions
Is polyurethane injection the same as floor stitching?
No. Polyurethane injection fills voids and restores support beneath settled concrete. Floor stitching uses epoxied rebar and new concrete to reinforce qualifying cracks within the slab.
Does every concrete slab crack need to be repaired?
No. The crack’s width, length, elevation change, location, and possible cause should be evaluated. Some cracks can be monitored, while others may require floor stitching or a more extensive repair.
The Bottom Line
Ellie’s and Grant’s projects were different, but both reviews describe the same OFS standard: knowledgeable evaluation, honest communication, precise workmanship, respectful cleanup, and a team committed to the homeowner’s satisfaction.
If you are experiencing cracked, uneven, or settled concrete in Oklahoma City or elsewhere across the state, begin with the OFS Free Foundation Health Check or schedule a free professional evaluation.
OFS will determine what your concrete slab needs and recommend an appropriate solution, no more and no less.
