Slab Foundation Repair
Concerned about a slab foundation? Get a Free Estimate
A slab foundation is a concrete foundation that sits close to the ground, so a loss of support underneath can affect floors, walls, doors and other parts of the house. Cracks in a slab are not all alike, and the location, size, pattern and progression of a crack all matter.
Slab problems are common on the Galveston County mainland, where expansive clay soils swell during wet periods and shrink during droughts, and a slab can lose support unevenly as a result. Plumbing leaks under the slab, poor drainage and large trees close to the house can make the movement worse. Many newer homes in the area are built on post-tension slabs, which contain tensioned steel cables, so any repair that involves cutting or drilling into the concrete has to account for where those cables run.
Galveston Foundation Repair helps homeowners understand slab foundation concerns before deciding how to respond. We consider the condition of the slab, the symptoms you have noticed, the site conditions and the way the home is responding. If your slab foundation has changed,

Slab foundation repair may involve addressing settlement, movement, cracking or areas where support beneath the slab has changed. The right method depends on the property's specific conditions.
Address areas where parts of a slab have settled and caused changes in the home.
Investigate uneven movement and its effects on floors, walls, doors and other parts of the structure.
Evaluate significant or changing slab cracks in the context of the whole foundation.
Look at sloping floors and related symptoms that may be tied to slab movement.
Account for the tensioned cables inside post-tension slabs when planning any repair that touches the concrete.
| Scope | Typical Range | What It Often Involves |

| Minor slab repair | $1,500–$5,000 | A localized area of settlement |
| Moderate slab repair | $5,000–$12,000 | One side or section of the slab |
| Major slab correction | $12,000+ | Several sections or whole-house correction |
Planning ranges only. Actual slab repair costs depend on the extent of movement, the repair method, access, site conditions and the condition of the structure.

We keep the whole slab in mind when reviewing cracks, settlement and movement, including how post-tension slabs differ.
