Slabjacking Company – Saint Louis, MO 63139

Slabjacking in 63139 handles concrete problems. It is not uncommon to discover concrete slabs that have damaged and settled. If the dirt under a layer of concrete settles or washes away caused by a water leak or other problems, a section of the slab is going to be unsupported, so the underside of the slab will be in tension. If the slab breaks because of its limited strength in tension, some of it will sink down to the base of the hole or recessed spot. A settled or moved slab is often a problem if it happens in a garage, basement or sidewalk. The busted, tilted and irregular surface should be repaired so that it won't pose a safety hazard.

Fortunately, a settled or sunken slab in 63139 is frequently brought back to level (or close to it) by a procedure called mudjacking, also known as slabjacking. Performed by a skilled foundation repair contractor, mudjacking can be a permanent fix that restores a slab to its initial state (However, the reason for the soil settlement or removal needs to be identified and eliminated before the repair occurs, to guarantee against a new void developing.

Using Slabjacking to Fix Broken Concrete Slabs

Mudjacking works by pumping a cement grout or "slurry" underneath the slab. After the slurry flows into the voids and fills all the bare spaces beneath the slab, it begins to apply hydraulic pressure, pressing the slab up towards its initial placement. A skilled foundation repair specialist knows when it is necessary to quit pumping. Once the slurry hardens, cracks are usually filled and slight discrepancies in level may be adjusted (if necessary) by applying a skim layer of mortar over the region.

As a result of specialized tools and training required to pump concrete under pressure and the messiness of the procedure, mudjacking in Saint Louis, Missouri 63139 is best done by an experienced foundation repair contractor. The holes by which the slurry is pumped must be strategically placed and sized to snugly fit the hoses that convey the mixture. The consistency of the slurry might be varied based on how much lifting pressure is required; a thicker blend could lift heavier slabs. Typical ingredients in the slurry include Portland cement, sand, flyash (a byproduct of coal combustion) and different additives that help protect against shrinking.

The prize for this work is a slab which comes close to its initial condition, and can stay like that as long as soil settlement doesn't reoccur. Mudjacking to correct a settled slab in Saint Louis, Missouri 63139 typically costs less than 1 / 2 the price of completely replacing the old slab with a new one.
