Mudjacking in Saint Louis, MO 63101 solves concrete problems. It's not uncommon to find concrete slabs which have cracked and settled. If the soil beneath a concrete slab settles or washes away because of a water leak or other problems, a section of the slab will likely be unsupported, so the bottom of the slab will be in stress. If the slab breaks or cracks due to the limited strength in pressure, some of it will certainly sink right down to the bottom of the hole or recessed spot. A settled or shifted slab is often a problem if it occurs in a garage, basement or sidewalk. The broken, tilted and uneven surface must be repaired so that it will not pose a safety hazard.

Using Slabjacking to Fix Broken Concrete
Mudjacking functions by pumping a cement grout or "slurry" beneath the slab. After the slurry flows into the voids and fills up all the vacant spaces underneath the slab, it starts to exert hydraulic pressure, pressing the slab up towards its original position. An experienced foundation repair professional understands when it's required to quit pumping. When the slurry hardens, cracks can be filled and slight differences in level can be fixed (if necessary) by applying a skim coat of mortar over the area.
Because of the specialized gear and education necessary to pump concrete under pressure and the messiness of the procedure, mudjacking in Saint Louis 63101 is better done by a seasoned foundation repair contractor. The holes through which the slurry is pumped must be logically placed and measured 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 mix may lift more substantial slabs. Common substances inside the slurry include Portland cement, sand, flyash (a byproduct of coal burning) and various additives that help protect against shrinking.
The reward for this work is a slab which comes near to its initial condition, and can remain that way as long as soil settlement does not reoccur. Mudjacking to correct a settled slab in Saint Louis, MO 63101 usually costs less than 1 / 2 the cost of totally replacing the old slab with a brand new one.
