Slabjacking – Hanley Hills 63133

Mudjacking in Hanley Hills, Missouri 63133 handles concrete problems. It's not unusual to discover concrete slabs that have damaged and settled. If the dirt under a concrete slab settles or washes away due to a water leak or any other problems, a piece of the slab is going to be unsupported, so the underside of the slab will be in tension. If the slab breaks due to the limited strength in pressure, part of it will sink right down to the bottom of the hole or recessed area. A settled or shifted slab is generally a problem if it occurs in a garage, basement or footpath. The broken, tilted and irregular surface has to be repaired so that it will not pose a safety hazard.

The good news is, a settled or sunken slab in Hanley Hills 63133 is often brought back to level (or close to it) by a procedure called mudjacking, also known as slabjacking. Performed by a skilled foundation repair contractor, mudjacking can be quite a permanent repair that restores a slab to its initial state (However, the reason for the soil settlement or removal needs to be identified and eradicated before the repair occurs, in order to ensure against a new void developing.

Using Slabjacking to Fix Damaged Concrete

Mudjacking works by pumping a cement grout or "slurry" beneath the slab. After the slurry streams into the voids and fills up all the bare spaces beneath the slab, it starts to apply hydraulic pressure, pressing the slab up toward its original position. An experienced foundation repair specialist knows when it's important to cease pumping. Once the slurry hardens, cracks could be filled and slight differences in level may be corrected (if needed) by applying a skim coat of mortar over the area.

Because of the specialized gear and training necessary to pump concrete under pressure and also the messiness of the process, mudjacking in Hanley Hills, MO 63133 is best done by a seasoned foundation repair contractor. The holes through which the slurry is pumped have to be strategically placed and measured to comfortably fit the hoses that convey the mix. The consistency of the slurry can be varied based on how much lifting pressure is needed; a fuller mix may 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 prize for this work is a slab that comes close to its initial condition, and can remain like that as long as soil settlement doesn't reoccur. Mudjacking to repair a settled slab in Hanley Hills 63133 typically costs less than 1 / 2 the price of completely replacing the old slab with a brand new one.
