If one thing that no one wants to hear as a homeowner, it is that they have problems with their foundation. Although some foundation issues are minor and easily fixable, other more complex problems require professional foundation repair services to fix the foundation. Early diagnosis and fixation of foundation problems can help in protecting the structure of the building. When talking about repairing foundations, different methods are used for repairing the different types of foundation structures. This article discusses slab vs crawl space foundation in terms of repair methods.
Slab Structural Repair
Regarding slab vs crawl space foundation, professional foundation repair experts recommend different repair methods for both. Here listed are the top slab foundation repair methods:
- Foam Jacking
Polyurethane foam jacking is one of the most effective methods to repair the sinking or settling slab foundation. Experienced technicians create a checkerboard pattern over the problematic area, drill holes into the slab, and inject high-density foam under the foundation. Within seconds, the foam expands, which further raises the concrete and fills in the empty spots.
- Masonry patches and sealants
The masonry patches and sealants method is considered ideal if there are cracks in the slab foundation due to shrinkage. Patches and sealants in the form of hydraulic cement set extremely fast and harden once mixed, further stopping water and leaks in the foundation.
- Steel piers
Steel piers are solid and, thus, offer more permanent foundation repair. They are driven down into the bedrock to prevent soil from shifting closer to the ground’s surface.
Crawl Space Structural Repair
The below-listed are the most common repair options for repairing the crawl space foundations:
- Lifting the foundation and extending the support
The technicians lift the floor upwards and then use blocks of wood to fill in the gaps between the tops of the support and the lifted floor. Furthermore, if the crawl space supports have sunk into the ground, then contractors try to add additional shimming to extend the height of the support.
- Repairing the damaged wood
In case there is damaged wood, then the same is ripped out and removed by the contractor. The contractor completely rebuilds the crawl space foundation structure by adding new wooden pieces. To ensure a more permanent solution, it is essential for the homeowner to address all sources of water and humidity to prevent mold and moisture.
A homeowner might be experiencing foundation issues due to several reasons. When the foundation of a home is at stake, it is crucial to address these issues quickly by using the best method for the specific situation. Now those different repair methods are used for repairing slab vs crawl space foundation issues, approaching the proper method for a particular foundation type is significant. Therefore, a homeowner should find a contractor who knows the method that will work best for both types of foundational structures.
