What is Slab Jacking?

Over time, the foundation of a concrete slab may settle and compact
In order to lift and level the slab, high-capacity jacks are placed under the foundation and on top of piercaps or jacking pads. The level of the slab is monitored with our "Compu-level". Once lifting is complete, sacrificial steel posts are locked off and the jacks removed. Then reinforced concrete is placed to support the footing in its new position. Grout is then pumped under the slab to fill the void spaces beneath.

1. As this happens, the concrete slab may shift and sink as well, leaving you with a problem.Slabjacking, or Mudjacking, as it is also known, is the process of repairing this fault by drilling 1 1/4 inch holes in the slab and injecting a slurry of lime, portland cement and water, under controlled pressure, to fill the voids left by the settled foundation
   
2. Once the void is filled, the slurry 'floats' the slab back into position, repairing the problem
   
3. By carefully controlling the pressure and proportions of materials used, we can ensure that the slab is placed precisely and ensure that the material won't shrink or settle with time.Once the slab is in place, we clean and patch the drilled holes
   
4. Over time the patches blend in with the surrounding cement.
