When a concrete slab sinks, it often cracks as well. This sidewalk not only looks bad; it's also unsafe for pedestrians and bicyclists.
Notice how much newer the damaged concrete is than the stable slabs around it. Replacement was not a long-term solution in this case, because the original problems with the soil were not addressed.
The Problem:
Broken and/or misaligned concrete (sidewalks, patios, driveways, etc.) poses a safety hazard, while also detracting from appearance and real estate value.
Telltale Signs:
What Caused It:
The soils underneath the concrete were either washed away or unable to support the weight of the masonry.
How to Fix It:
We fix smaller concrete slabs that have settled using a technique called mudjacking, slabjacking or grout injection. This process involves pumping a mixture of water, soil, sand, and Portland cement underneath the slab to fill voids and (in some cases) raise the slab back up.
We can fix your sinking outdoor concrete problems and get it looking like new again! Call us for a free sinking concrete repair quote today!

Concrete is heavy! When the soils underneath a concrete slab are unable to support its weight, the slab will sink. If part of the concrete slab is supported by soils and other sections are not, the unsupported pieces may crack away from the other section.
The soils underneath an outdoor concrete slab can fail to support the weight of the slab for these two primary reasons:
Different types of soil have different load-bearing capacities. When a soil's load-bearing capacity is exceeded, the soil will compact and settle.
It's also possible for the soil beneath a slab to settle and compact of its own accord. Soil that contains large amounts of clay and/or silt will shrink substantially when it gets dry.
As the soil compacts underneath a concrete slab, the unsupported slab will sink as well, usually cracking in one or more spots.
The soil that is underneath your driveway, patio, or concrete steps may not necessarily remain there to provide adequate support for the concrete element.
As water moves underneath your concrete slabs, it can wash away the soil that's supporting the weight of the concrete. As this happens, it creates a void, or empty space, underneath. Over time, with nothing to support it, your concrete slab can begin to sink or cave in.
Water has washed away the soils underneath a section of this concrete sidewalk.
As it did, a void, or hollow area, was created underneath the concrete. With nothing to support it, the concrete eventually collapsed.
Mudjacking is a repair technique that can stabilize sinking concrete by filling in empty spaces or voids with a mixture of "mud" or "slurry." This is a fast, effective process that can usually be completed in less than a day.
This "slurry" mixture is composed of water, soil, sand, and Portland cement that will harden to create a stable supporting base underneath the concrete slab.
Mudjacking will do more than simply stabilize the sinking concrete. As the slurry is pumped underneath the concrete slab, it will also lift the slab, potentially returning it to its original position.
As slurry cures, it creates a long-lasting, sustainable solution for supporting the weight of the concrete above.
Slurry will not be affected by compaction and washout like your previous soils were, and mudjacking (aka slabjacking) costs much less than demolishing and reconstructing sunken concrete.
