Slabjacking Company – Saint Louis, Missouri 63101
Slabjacking in Saint Louis, Missouri 63101 handles concrete problems. It's not uncommon to discover concrete slabs which have cracked and settled. When the soil below a layer of concrete settles or washes away as a result of water leak or other problems, an area of the slab is going to be in need of support, so the underside of the slab will be in stress. If the slab breaks because of its restricted strength in tension, some of it will certainly sink down to the bottom of the hole or recessed region. A settled or moved slab is often a problem if it happens in a garage, basement or sidewalk. The broken, tilted and irregular surface should be repaired so that it will not pose a safety hazard.
Thankfully, a settled or sunken slab in Saint Louis, Missouri 63101 is frequently brought back to level (or close to it) by a process called mudjacking, also referred to as slabjacking. Performed by a skilled foundation repair company, mudjacking can be a permanent fix that restores a slab to its original state (However, the reason for the soil settlement or removal needs to be identified and eliminated before the repair happens, to guarantee against a new void forming.
Using Mudjacking to Fix Broken Concrete Slabs
Mudjacking works by pumping a cement grout or "slurry" underneath the slab. After the slurry streams into the voids and fills all the bare spaces beneath the slab, it starts to apply hydraulic pressure, pushing the slab up toward its initial position. An experienced foundation repair professional knows when it's important to quit pumping. Once the slurry hardens, cracks can be filled and slight discrepancies in level may be adjusted (if needed) by applying a skim coat of mortar over the spot.
Because of the specific equipment and education needed to pump concrete under pressure and the messiness of the process, mudjacking in Saint Louis 63101 is best done by a seasoned foundation repair company. The holes by which the slurry is pumped have to be logically placed and sized to comfortably fit the hoses that convey the mixture. The consistency of the slurry can be varied based on how much lifting pressure is required; a thicker mix could lift heavier slabs. Typical ingredients in the slurry include Portland cement, fine sand, flyash (a byproduct of coal combustion) and various chemicals that help prevent shrinking.
The prize for this work is a slab which comes close to its original condition, and will remain like that as long as soil settlement does not reoccur. Mudjacking to fix a settled slab in Saint Louis, Missouri 63101 normally costs less than half the price of totally replacing the old slab with a brand new one.
