If your garage floor, your concrete driveway, or your concrete patio is cracking or sinking; if the concrete slab of your home seems out of level or uneven then there may be some underlying issues worth investigating. If your house is built on a concrete slab then you may have also discovered symptoms like cracks in walls (sheetrock, drywall, or plaster), issues with doors operating properly, separation within the flooring materials, and/or sloping within the surface of the slab. If you have noticed any of these issues and wish to receive input and assistance then please feel free to contact us for a free evaluation. Some of these items can simply be a result of aging and shrinking of the concrete materials, but they can also be symptoms or signs of more significant issues.
With well over 100 years of combined experience, Carolina Foundation Solutions can provide the best solutions available to resolve your concrete slab problems. It is our goal to provide alternatives to tearing out and replacing concrete, by offering methods which address the root cause of such issues. We work with many reputable licensed engineers throughout the Carolinas to help determine the precise problems and the proper solution.
The development and presence of cracks within concrete should be expected. As concrete ages it undergoes a drying and shrinkage process. This is an everlasting process and will result in cracks due to the loss of water or moisture content. Therefore, it is important to determine if the cracks found within concrete are simply shrinkage cracks that are to be expected or something that warrants repair. The magnitude or width of cracks and the presence of vertical displacement along the cracks are often two of the determining factors. Vertical displacement along the cracks is often present when settlement of the slab has occurred. A slab settling (or slab sinking) can be a result of many factors but it is generally caused by movement within the soils that it rests upon. The movement within the underlying soils can be a result of factors such as periods of drought conditions, periods of heavy rainfall, consolidation of backfilled soils that had been poorly compacted, decomposition or decay of materials within the soils, drainage issues, a lingering plumbing leak, erosion, and/or simply the presence of poor native soils. Just as the cause for the movement within the soils (and consequently the slab) can vary, the solutions or repairs required can vary.
Depending on the severity and the cause of the cracks, it could require the epoxy injection repair or an epoxy stitch weld repair. This epoxy injection repair consists of applying or injecting a high strength epoxy compound within the existing cracks to bond and seal the severed areas. The epoxy stich weld repair requires injecting the epoxy material along with carbon fiber strips or staples, as a means of providing additional reinforcement. In the event that the cracks are a result of substantial movement within sections of the concrete and stabilization and potentially lifting of the slab is required then the most common options are the pressure grouting procedure, the polyurethane foam injection grouting, and/or the installation of helical piers with slab brackets.
Carolina Foundation Solutions also specializes in performing the polyurethane foam injection grouting procedure. Polyurethane foam injection grouting is a type of pressure grouting and is performed in a very similar manner to that of other grouting, but creates less mess, requires less time for curing of the materials, and can be done by drilling much smaller holes. Once holes have been drilled through the concrete, we inject an Alchemy Polymers polyurethane foam product, which is a two component, high strength, hydro-in-sensitive structural polymer foam. The material is light weight and provides immediate results. The injected materials will fill any voids that may exist between the bottom of the concrete slab and the top of the soils, will consolidate loose / soft soils located along the upper layers of the underlying soils, will create a more solid base which shall assist in preventing further and future movement, and will allow the ability to lift the settled areas of the concrete slab.
Pressure grouting is a cost-effective method of providing repairs to settled or sunken sections of concrete slabs. This type of repair is also often referred to as slab jacking, slab lifting, or mud jacking. It consists of drilling small holes through the surface of the settled or sunken section(s) of the concrete slab and then pumping a cement based or mud based grout material through a hose into each hole. The injected materials will fill any voids that may exist between the bottom of the concrete slab and the top of the soils, will consolidate loose / soft soils located along the upper layers of the underlying soils, will create a more solid base which shall assist in preventing further and future movement, and will allow the ability to lift the settled areas of the concrete slab.

Another common option for providing repairs to settled sections of concrete slabs is the installation of helical piers with slab brackets. The helical piers transfer the weight of the concrete from the base of the slab down to a layer of suitable load bearing soils. This method of repair is generally the most ideal when the underlying soils are soft and unstable at depths well beyond the first few feet from the surface.
Carolina Foundation Solutions specializes in providing many of the various repairs for cracked and settling concrete slabs. We have years of experience performing pressure grouting, performing epoxy injection and stitch weld repairs, and installing helical piers. We are equipped with the latest technology in concrete pumps, have invested in superior polyurethane foam injection systems, and use only the most reliable materials in the industry.
