How to Repair Uneven Concrete Slabs

Effective solutions for leveling your uneven concrete slabs

Have a look at the various ways you can level a concrete patio.

Uneven concrete is extremely frustrating. Whether it's a driveway, sidewalk, or anything in between, once the concrete settles, you could face anything from an eyesore to a liability in the form of a trip hazard.

Thankfully, there's a wealth of options available if you're dealing with uneven concrete around your home. This variety of solutions puts you in the driver's seat, allowing you to choose the best approach for your specific needs.

At Holland Custom Concrete, we've been honing our skills in lifting and repairing settled concrete for many years. Our extensive experience has led us to understand and master every common, effective method for fixing an uneven concrete slab.

In this article, we will overview four options for leveling concrete slabs and teach you to spot the right approach for your house.

Lift the Uneven Slabs Back Up

Many homeowners who deal with settled or sinking concrete need to be made aware that they can actually lift and level it. The process, known as concrete leveling, involves drilling holes in the slabs that have settled. A compound is pumped underneath the concrete to fill the voids, helping lift the concrete back to the designed level before hardening and forming a new base.

Concrete leveling repair, whether it's polyurethane foam leveling, stone slurry grout leveling, or mud jacking, is a reliable and cost-effective solution. It not only restores your existing concrete but also saves you from the high cost and hassle of concrete replacement.

Replace the Uneven Slabs

When the slabs are severely cracked or otherwise damaged, replacement will be necessary. Of all the options discussed, replacement is the most time-consuming and expensive option, but it also offers the longest-term solution. Adequate preparations and installation considerations must be made when replacing the slabs in the yard to avoid future settlement problems.

Stamped or decorative concrete is a great alternative to a traditional concrete slab. This can add a touch of charm to your property while also providing a usable and strong surface. Be sure to use a professional concrete contractor for a project like this one.

Grind Down the Uneven Areas

One possible solution is to grind down the higher spots to match the lower spots; however, this requires specialized equipment and should be done by a professional who knows how to properly grind it down without damaging the surrounding concrete.

Grinding the mismatched slabs down can also help increase drainage by creating a slope away from your house. Leveling up minor differences in elevation between slabs can be effective. When it comes to more serious cracks and settling issues, a little concrete work can go a long way.

Add New Concrete or Other Compounds Over the Sunken Slabs

Or, you could choose a final finish by pouring new concrete on top—a 'topping'—but only if you have sorted out permanent remedies to stop any further settlement before you do so.

Second is concrete, which can be mixed for self-leveling resins and cementitious overlays specifically designed for repairing uneven slabs, available on the market. This is by far the quickest, simplest, and most affordable solution but will only last for a while compared to leveling or replacing the slab.

Interior Floors vs. Exterior Slabs

Solutions differ based on whether the slab is a floor in the interior or the exterior of a building. If a floor is a major interior slab, then generally grinding down or top-poured (for large cracks) leveling is a good technique. As long as the slab is still attached, there should not be any structural concern as long as massive elements are not involved. Conversely, exterior slabs usually require more extensive repairs such as leveling or replacement because of exposure to weather and elements, as well as heavy foot traffic. Whenever possible, the underlying drainage issue that caused the settlement should also be repaired.

How Should You Fix Your Uneven Concrete?

Fixing uneven concrete slabs can seem tricky, but it doesn't have to be! The best method really depends on how bad the settlement is, your budget, and the look you want. It's smart to get a professional concrete contractor to check it out and suggest the best fix.

Regular maintenance and handling of any underlying issues can stop problems from coming back. With the right care and timely repairs, your property will stay safe and look great. Don't let uneven concrete slabs slide—tackle them now to avoid bigger headaches later.
