Mudjacking Company – Saint Louis, MO 63178
Slabjacking in Saint Louis 63178 handles concrete problems. It is not unheard of to discover concrete slabs that have cracked and settled. When the soil below a layer of concrete settles or washes away due to a water leak or any other problems, a piece of the slab is going to be unsupported, therefore the underside of the slab will be in tension. If the slab breaks or cracks because of its restricted strength in pressure, part of it will sink down to the bottom of the hole or recessed spot. A settled or shifted slab can be a problem if it happens in a garage, basement or sidewalk. The broken, tilted and uneven surface has to be repaired so that it won't pose a safety hazard.
Fortunately, a settled or sunken slab in Saint Louis, Missouri 63178 can often be brought back to level (or in close proximity to it) by a procedure referred to as mudjacking, also referred to as slabjacking. Performed by an experienced foundation repair company, mudjacking can be a long term repair that restores a slab to its initial state (However, the reason for the soil settlement or removal needs to be found out and eradicated before the repair takes place, in order to ensure against a new void developing.
Making Use of Mudjacking to Repair Destroyed 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 vacant spaces underneath the slab, it actually starts to exert hydraulic pressure, pushing the slab up towards its original placement. An experienced foundation repair specialist understands when it's required to quit pumping. When the slurry hardens, cracks can be filled and slight differences in level can be remedied (if needed) by applying a skim coat of mortar over the area.
Because of the specific tools and training necessary to pump concrete under pressure and also the messiness of the procedure, mudjacking in Saint Louis 63178 is better done by an experienced foundation repair contractor. The holes by which the slurry is pumped should be tactically placed and sized to comfortably fit the hoses that convey the mixture. The consistency of the slurry could be varied depending on how much lifting pressure is required; a fuller mix could lift heavier slabs. Typical elements in the slurry include Portland cement, fine sand, flyash (a byproduct of coal combustion) and different chemicals that help reduce shrinking.
The pay back for this work is a slab which comes in close proximity to its initial condition, and will remain that way as long as soil settlement does not reoccur. Mudjacking to fix a settled slab in Saint Louis, Missouri 63178 normally costs less than 1 / 2 the price of completely replacing the old slab with a new one.
