Slab jacking, also known as mudjacking, is a foundation repair technique used to lift and level sunken concrete slabs, such as sidewalks, driveways, patios, or floors inside a home. It’s a cost-effective and less invasive method compared to replacing the entire concrete surface.
How it works:
Small holes are drilled into the sunken concrete slab. A special mixture—usually made of water, cement, sand, and other materials—is then pumped under the slab. This mixture fills the empty space beneath and creates pressure, lifting the concrete back to its original position. Once the slab is level, the holes are patched, and the area is cleaned up.
Why it’s used:
Slab jacking is ideal when the soil underneath a concrete slab has settled or eroded, causing uneven surfaces. It’s commonly used for non-structural repairs and works best for concrete that is still in good condition but has shifted due to soil movement.
This method is quick, affordable, and can often be completed in just a few hours, making it a popular choice for minor foundation repair and concrete leveling needs.
