uneven sidewalk

Concrete is used in a variety of applications in and around your home including driveways, sidewalks, patios, and even pool decks. Concrete’s versatility makes it a popular building material, but it can also cause loads of frustration and dangerous situations when the concrete begins to settle and shift, creating uneven ground.

What Causes Concrete To Become Uneven?

In the same way that your home can settle and shift when the ground beneath it moves, concrete slabs can also shift over time. Hydrostatic pressure and expansive soils can cause the ground beneath the concrete to raise and lower. Also, the weight of items sitting on the concrete can also cause the soil to compact over time. Once your concrete has become uneven, it’s important to find a concrete leveling solution to prevent tripping and falling.

What Types of Concrete Leveling Techniques Are Available?

There are a variety of concrete level techniques available. It’s important to find the right solution for your situation.

Mud Jacking

Mud jacking, also known as slab jacking, is a popular method for raising concrete to a leveled state. Mud jacking involves drilling several holes in the existing concrete slab and then injecting a slurry mixture made of crushed limestone, mud, cement and sand beneath the concrete. 

The downside to mud jacking is that the mixture that gets injected is fairly heavy and that extra weight can actually make the problem worse over time. Slab jacking also takes a good amount of time for the slurry to set beneath the concrete, so you won’t be able to walk on it until it is fully cured.

To boot, you will have holes in the concrete slab that show that it has been repaired.

Concrete Leveling with High Density Polymer

A similar concept to mud jacking is concrete leveling using polymer (often called poly or poly leveling). A much smaller hole is drilled into the concrete slab and the polymer is injected beneath the concrete. The polymer spreads beneath the slab to evenly fill voids and raise the slab to an even level.

Another advantage to using polymers is that they are lighter and can actually stabilize the soil beneath the slab to prevent further sinking and shifting. In addition, poly leveling is a much less expensive option than completely replacing the concrete.

Concrete Replacement

The most expensive option is obviously to have the concrete removed and replaced. Not only is this a costly investment, but the old concrete typically ends up in landfills. To top it all off, building concrete forms, pouring new concrete, and letting it completely cure is a much more lengthy process which means that your driveway, patio, pool deck, or sidewalk will be out of commission for a greater length of time. Of course, if your concrete is damaged, cracked, and falling apart, this may be your only replacement option.
