What is Mudjacking or Slabjacking?
If your concrete is sinking. there is a very good possibility that the concrete slab was installed on poorly compacted fill dirt. Sub-surface erosion and shrinking soils are also possibilities. Concrete Alternatives can float a slab back to its original position by pumping a mixture of topsoil, sand, cement, and other additives beneath your slab. We simply drill strategically placed holes into the slab. Using a portable pump and flexible hoses, we fill these holes with the special mixture. Lifting a slab using this method can often be accomplished in a few hours. Often the cost to perform this service is less than half that of replacing a new slab.
There are numerous benefits to mud or slabjacking :

The holes are patched using a concrete mixture.
Why concrete sinks in the first place:
Fill dirt is almost always placed along side of house and garage foundations after the foundation work is completed. This fills in voids created during the foundation construction process. Rarely does a builder take the time to compact this dirt. Soils consist of solid particles and the spaces (voids) between these particles. However, void spaces in soil can cause big problems for buildings and concrete slabs. Concentrated loads, such as buildings or slabs can literally squeeze air and water from soils. When this happens, the soil sinks and the buildings or slabs follow closely behind. Slabjacking can be used to raise porches, pool decks, walkways, basement floors, driveways, garage floors, patios, etc. Slabjacking can help you remove trip hazards, pooling water, and fill voids.
If it's concrete, and it has sunk, chances are that Concrete Alternatives is the solution for you!
