Concrete lifting, slab jacking, and mud jacking are three different methods used to raise and level sunken concrete slabs. While they all achieve the same end goal, there are some differences in the techniques used to accomplish it.
- Concrete lifting:
- Concrete lifting is a process of lifting sunken concrete slabs by drilling holes into the surface and injecting a polyurethane foam mixture underneath. The foam expands, filling the voids and lifting the slab back to its original position. This technique is also known as polyjacking or foam jacking.
- Slab jacking:
- Slab jacking, also known as mud jacking or pressure grouting, is a process of lifting sunken concrete slabs by pumping a mixture of sand, cement, and water (or mud) underneath the slab. As the mixture fills the voids beneath the slab, it lifts it back to its original position.
- Mud jacking:
- Mud jacking is similar to slab jacking, but it involves pumping a mixture of water, soil, and cement (or mud) under the sunken slab. This mixture is heavier than the sand-cement mixture used in slab jacking, which makes it a more suitable option for lifting larger slabs.
Some key differences between these methods include the materials used, the weight of the lifting material, the injection process, and the cost. Concrete lifting using polyurethane foam tends to be the most expensive option, but it also provides the most accurate and long-lasting results. Slab jacking with sand-cement mixture is a more affordable option, but it may not be as precise and the results may not last as long. Mud jacking is typically the most affordable option, but it is not suitable for all types of concrete slabs and may require more maintenance over time.
