Mudjacking Company – Saint Louis, MO 63124
Mudjacking in Saint Louis, Missouri 63124 handles concrete problems. It isn't unusual to discover concrete slabs which have cracked and settled. When the dirt beneath a layer of concrete settles or washes away as a result of water leak or other issues, a section of the slab will be in need of support, so the underside of the slab will be in tension. If the slab breaks because of its restricted strength in pressure, some of it will certainly sink right down to the base of the hole or recessed spot. A settled or shifted slab can be a problem if it occurs in a garage, basement or footpath. The broken, tilted and unequal surface has to be repaired so that it will not pose a safety hazard.
Thankfully, a settled or sunken slab in Saint Louis 63124 can often be brought back to level (or close to it) by a process known as mudjacking, also known as slabjacking. Performed by an experienced foundation repair company, mudjacking can be a long-lasting fix that restores a slab to its initial state (However, the cause of the soil settlement or removal needs to be discovered and eradicated before the repair happens, in order to ensure against a new void forming.
Using Slabjacking to Repair Damaged Concrete
Mudjacking works by pumping a cement grout or "slurry" beneath the slab. After the slurry streams into the voids and fills all the vacant spaces underneath the slab, it begins to exert hydraulic pressure, pressing the slab up towards its original placement. An experienced foundation repair specialist knows when it's necessary to cease pumping. When the slurry hardens, cracks are usually filled and slight differences in level may be fixed (if necessary) by applying a skim coat of mortar over the area.
Because of the specific tools and training needed to pump concrete under pressure and the messiness of the process, mudjacking in 63124 is better done by a skilled foundation repair contractor. The holes by which the slurry is pumped have to be logically placed and measured to snugly fit the hoses that convey the mix. The consistency of the slurry can be varied based on how much lifting pressure is required; a thicker blend could lift heavier slabs. Typical materials in the slurry include Portland cement, fine sand, flyash (a byproduct of coal combustion) and various additives that help stop shrinking.
The reward for this work is a slab which comes in close proximity to its original condition, and can remain that way as long as soil settlement doesn't reoccur. Mudjacking to correct a settled slab in Saint Louis, Missouri 63124 typically costs less than half the price of totally replacing the old slab with a new one.
