Mudjacking
As patios, walkways, driveways, and concrete steps sink, they can crack and create uneven surfaces. Sinking concrete is unsightly, and it can create a tripping hazard.
Traditionally, this problem is often repaired by a process called mudjacking.
Mudjacking (also known as):
- Slab Jacking
- Concrete lifting
- Concrete raising
- Grout pumping
- Slab leveling
Mudjacking: a repair technique for lifting concrete slabs that have settled over time with a mortar-based mix.
Mudjacking involves pumping a mortar-based mixture of “mud” or “slurry” underneath a settling slab. This injected material is a mixture of water, soil, sand, and Portland cement that cures to become a solid, stable fill.
As the mixture is pumped underneath the concrete slab, it fills all empty spaces and creates pressure on the slab that lifts the surface upwards. Once injected, the slurry will then harden into a solid fill that’s more stable than the soil, yet lighter than concrete.
Baker’s Waterproofing offers a fast, effective, and less invasive approach to concrete leveling with PolyRenewal™. The PolyRenewal™ system involves injecting an expanding polymer foam under the concrete for a durable, long-lasting solution.
When is Mudjacking NOT appropriate?
Mudjacking is effective for heavier concrete structures when used in conjunction with slab piers. It should not be considered as a standalone solution to lifting a footing or floor slab that has settled in your home.
In most cases, mudjacking alone will not be able to lift both a slab and the heavy partition walls that sit on top of it. In cases where mud jacking isn’t effective, we often recommend installing slab piers instead.
If mudjacking does lift the concrete slab, it may be difficult to control where mudjacking lifts the walls, causing them to lift unevenly.
More importantly, this kind of concrete repair solution is temporary. Even with the voids filled, the soil below is likely to continue settling over time. Ultimately, you’d have to call your contractor to your home over and over again to repeat the mudjacking process — or call someone who can use a different solution that can fix it once and for all!
Mudjacking is also not appropriate as a “do-it-yourself” repair. Mudjacking requires special equipment and professional experience. All work should be done through a trained, professional mudjacking contractor who has excellent knowledge of local soil conditions.
