Foundation issues can be a result of not getting a void underneath your slab filled. Dallas Foundation Repair is here to talk about what causes these voids, and what can be done to fix them.
How are Voids Created Underneath Slab Foundations?
The list of ways that a void can develop underneath a slab foundation is long. Here are some of the most common reasons that these voids happen.
– Hydrostatic Pressure: If there isn’t proper drainage on your property, water can accumulate underneath the slab foundation as storms and irrigation happen. This can cause pressure that leads to cracking.
– Erosion: Soil erosion is one of the most common reasons that voids happen. If you have leaky plumbing or drainage problems, soil can get washed away as it accumulates around the foundation.
– Pests/Animals: If you have pests or animals burrowing underneath your foundation, it can cause a void that can be extremely damaging. This usually happens slow and can take months to become a large problem.
– Drought: Just like too much moisture is a problem, not enough is a problem as well. Dry soil shrinks and can leave voids and cracks that are a problem.
– Settlement: There is a lot of preparing that happens before a home is built so that settling doesn’t occur afterwards. If the soil wasn’t compacted enough, it can lead to voids caused by settling.
How Do You Fill a Void Under Concrete?
There are a few different ways that a void can be filled under your foundation.
– Mudjacking: Using a cement slurry, the void beneath a foundation can be filled. This is a solution to the problem that can be the most affordable, but it isn’t always the best solution. There is no way to know for sure if the slurry has filled all the pockets that are present, and it also takes time to cure. Another problem is that when the cement has solidified, it can present issues with plumbing repairs should they be needed.
– Foam Injection: If erosion is the problem, foam injection could be the answer. Foam is injected to fill the void that is there and expands so that the entire space and cracks are completely filled.
– Sectional Repair: Portions of the damaged slab are broken and removed with this method. After the void is filled with sand and then compacted. Once that is done, a concrete mixture is poured into the space to finish off the repair.
