Mudjacking. A type of sand-cement slurry (called “mud” in the industry) can be used to fill voids under concrete slabs. This mixture of sand, cement, and water is pumped through holes drilled in a slab foundation to fill voids underneath.
How to Fill Hole Next to Foundation?
Filling holes next to a foundation can be a tricky task. In most cases, these holes are caused by soil erosion or water runoff and can eventually lead to structural damage. Installing a retaining wall, filling the hole with concrete, or adding soil are all possible solutions. The most important thing to keep in mind is that the hole must be filled in a way that won’t cause further damage to the foundation.
The first step in fixing a hole next to a foundation is to assess the situation. Take a look at the size of the hole and the area around it. If the hole is small, you can use a shovel to fill it in with soil. If the hole is larger, you may need to add a retaining wall or fill the hole with concrete.
If the hole is caused by erosion, you may need to add soil around the foundation to prevent further erosion. This can be done by adding a layer of topsoil or straw around the foundation and using a rake to level it out. Once the soil is in place, you can fill the hole with soil.
If the hole is caused by runoff, you may need to install a retaining wall. This can be done by using bricks, stones, or concrete blocks.
