Using Mudjacking to Repair Broken Concrete Slabs
Mudjacking functions by pumping a cement grout or "slurry" underneath the slab. After the slurry flows into the voids and fills up all the empty spaces beneath the slab, it actually starts to apply hydraulic pressure, pushing the slab up toward its initial placement. An experienced foundation repair professional knows when it is needed to quit pumping. Once the slurry hardens, cracks could be filled and slight differences in level can be corrected (if required) by applying a skim layer of mortar over the spot.
As a result of specialized gear and training required to pump concrete under pressure and the messiness of the procedure, mudjacking in Saint Louis, MO 63139 is better done by a seasoned foundation repair contractor.

The consistency of the slurry may be varied based on how much lifting pressure is needed; a fuller mixture can lift heavier slabs. Common ingredients inside the slurry include Portland cement, fine sand, flyash (a byproduct of coal burning) and different chemicals that help prevent shrinking.
