Slabjacking – 63139
Slabjacking in Saint Louis, Missouri 63139 solves concrete problems. It's not unheard of to discover concrete slabs that have damaged and settled. If the dirt beneath a layer of concrete settles or washes away because of a water leak or other issues, a piece of the slab will be unsupported, therefore the bottom of the slab will be in tension. If the slab breaks or cracks because of its limited strength in pressure, some of it will sink right down to the base of the hole or recessed area. A settled or shifted slab is often a problem if it happens in a garage, basement or footpath. The broken, tilted and uneven surface must be repaired so that it won't pose a safety threat.

Making Use of Mudjacking to Fix Damaged Concrete Slabs
Mudjacking functions by pumping a cement grout or "slurry" underneath the slab. After the slurry flows into the voids and fills all the empty spaces beneath the slab, it begins to exert hydraulic pressure, pushing the slab up towards its original placement. An experienced foundation repair professional knows when it's needed to cease pumping. Once the slurry hardens, cracks may be filled and slight discrepancies in level may be corrected (if required) by applying a skim coat of mortar over the spot.
Because of the specific equipment and training necessary to pump concrete under pressure and also the messiness of the procedure, mudjacking in Saint Louis 63139 is best done by a seasoned foundation repair company. The holes by which the slurry is pumped have to be strategically placed and sized to snugly 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 ingredients in the slurry include Portland cement, sand, flyash (a byproduct of coal burning) and different additives that help protect against shrinking.
The reward for this work is a slab that comes close to its initial condition, and will stay that way as long as soil settlement doesn't happen again. Mudjacking to repair a settled slab in Saint Louis, MO 63139 normally costs less than half the price of totally replacing the old slab with a brand new one.
