Filling Voids Beneath a Slab
Camrock Foundations specializes in void fill. We are based out of Lutz, Florida, and service the entire Tampa Bay Area. If you have voids or empty spaces under your slab foundation you will need to have the area inspected for a foundation repair contractor to understand the repair needed. A void fill is a process of filling in empty spaces in a foundation with concrete, foam, or other materials. This can be done to repair cracks or other damage to the foundation, and prevent future problems. To prevent these problems, it is important to fill voids under a slab with a suitable material, such as concrete or grout. This will help to create a level, stable surface that is resistant to cracking and water damage.
Voids form under slabs for a variety of reasons, including:
Poor compaction of the soil: When the soil is not compacted properly, it can create voids or gaps underneath the slab. This can happen if the soil is too wet or too dry, or if the compaction equipment is not used correctly.
Decomposition of organic matter: Organic matter in the soil can decompose over time, leaving behind voids. This is more likely to happen in areas with a lot of vegetation.
Erosion: Erosion can also cause voids under slabs. This can happen if the soil is not protected from wind or water.
Settling: Over time, the soil can settle, creating voids underneath the slab. This is more likely to happen in areas with a lot of clay or expansive soils.
Voids under slabs can cause a number of problems, including:
Slab Movement: The voids can cause the slab to move, which can lead to cracks and other damage.
Reduced load-bearing capacity of the slab: As the voids can reduce the amount of concrete in contact with the ground.
Water infiltration: The voids can provide a path for water to enter the structure. This can also lead to additional problems such as mold and mildew.
To fill voids beneath a concrete slab, you can use a variety of methods, including:
Slurry Grout: Grout is a mixture of cement, sand, and water that can be used to fill voids when it’s rather larger.
Poly grouting : Foam is a strong lightweight material that can be used to fill voids and provide very good stability to the slab. It travels further and has many really good qualities over the traditional slurry grouting methods.
Camrock Foundations can help you determine if a void fill is necessary for your home. They will also be able to recommend the best type of material to use for your specific scenario. It is important to have voids repaired as soon as possible to prevent further damage to your slab and keep your home safe.
