Concrete Slab Repair in San Antonio
Slab Settlement and Slab Repair
Why do Texas homes need slab repair? Slab-on-grade foundations comprise a large number of home foundations in Texas. Shallow frost lines mean footings don’t have to be built deep—as they are in the north, which allow for a basement. Limestone bedrock in the central and western parts of the state, coupled with expansive clays soils and a high water table in the eastern part of the state, mean that slabs are a viable, relatively inexpensive foundation for new homes.
Soil Conditions Cause Problems
Slab settlement is a real issue, even for new homes, because they aren’t designed to resist heaving soils; they are meant to rise and fall with the changing soil conditions. The problem is that over time, the shrink and heave below your home can cause foundation damage and the need for either soil stabilization or slab repair.

Signs of Slab Settlement
Typically, a one-story home with a concrete slab directly on soil, surrounded by lots of trees and watered flower beds will be a hot spot for foundation problems. Homes in dry, warm areas with slabs close to the surface and footings an average of only two feet down are susceptible to foundation problems, as well. In Texas, the need for slab repair can be a result of either of these situations.
Is your floor uneven or starting to crack? Have you seen tripping hazards around your home? Settlement of concrete slabs can cause a huge problem and a great amount of stress on your home’s foundation.
Cracks in your sheetrock or brick point to a moving foundation. Additionally, sticking doors and windows not only indicate a sign of slab settlement, this poses a hazard.
Are Cracks in Concrete Slab Normal?
Some cracks are less threatening, but other concrete cracks should be taken very seriously. One of the first things to look at with cracks is their width. Cracks that are less than 0.3 millimeters wide are usually not an issue. But cracks wider than this can lead to structural problems.
If you are observing cracks in your foundation wall, check to see if they are vertical or horizontal. Vertical cracks are usually just a sign of minor shrinkage, which is not something to worry about.
If your home has cracks that allow water intrusion, this is something to take seriously through repairs and potentially waterproofing solutions.
One common type of crack happens shortly have concrete is placed to dry. It is called a "plastic shrinkage" crack and it occurs when too much water is mixed into concrete.
