Slabjacking is a method of raising concrete slabs that have settled and shifted. Sunken concrete can create several issues that are cause for concern. It can cause water to run towards the foundation of adjacent structures and lead to larger issues with the foundation. Sunken concrete can also cause trip hazards in sidewalks that become a safety and liability concern.
In many instances the cost for replacing the concrete is much higher than the cost of slabjacking. When only one area of concrete is replaced, it can cause an unsightly appearance because the new concrete will not match the older, weathered concrete. With most situations the better option is to use slabjacking.
To repair the concrete slab, All-Con Leveling drills a series of small holes through the slab and injects a limestone compound to raise the slab to the desired elevation and provide uniform support under the concrete. The small holes are then patched with a high-strength grout to match the existing concrete surface.
