Your concrete driveway and sidewalk may be the most-used parts of your home, and often the most under-appreciated. These areas are open to the elements and withstand a lot of traffic. They are strong, but it’s natural for them to sustain damage over time. Show your uneven driveway and sidewalk some TLC with a free inspection and innovative repairs from local concrete experts.

Why Your Driveway and Sidewalk are Uneven

Your driveway and sidewalk slabs can become uneven and damaged for many reasons. Here are a few of the most common causes of your concrete problems.

Unstable Soil

The soil is the root cause of most concrete problems like uneven driveway and sidewalk slabs. The expansive bentonite clay soil prevalent in Colorado is volatile and creates many issues for home foundations and concrete structures. The soil commonly falls victim to dry weather and drought by drying and shrinking. This leaves concrete above the soil without proper support, and the slabs will then sink and become uneven. During any heavy rain or snowmelt, the clay soil absorbs the water, expands, and presses up on the concrete with enough force to crack and even raise sections of the concrete so it is no longer even.

Poor Drainage

Your driveway and sidewalk are naturally exposed to the elements, but too much water is a bad thing. If your gutters are clogged or the downspouts drain water on or near your driveway or sidewalk, damage can ensue. So much water around your driveway and sidewalk can lead to soil washout and erosion, followed by sinking and uneven slabs. Water also can puddle in uneven areas and become slipping hazards and breeding grounds for pests like mosquitoes.

Too Much Weight

While concrete is a strong material, it does have its limits. This is especially true of driveways that have heavy vehicles parked on them for an extended period of time. The weight of the vehicle can be too much for the slabs and underlying soil to bear, and they will begin to sink and become uneven. Repeatedly driving over uneven concrete in your driveway can also damage your car and lead to more maintenance and repairs.


Yes, uneven concrete can typically be fixed and restored to its previous glory. However, if the concrete has sustained too much damage in the form of excessive cracks, dramatic settling, or missing chunks, other avenues of repair are needed. Concrete that isn’t badly cracked or uneven can be lifted and stabilized, but slabs that are beyond repair may need to be completely removed and repoured. This can be expensive and time-consuming, so it is best to fix concrete problems when you first notice them.

Problems with your concrete, such as cracking and uneven driveway and sidewalk slabs, not only make your property look bad, but they are dangerous. Anyone walking over these uneven surfaces, especially those with mobility issues, can easily trip, fall, and hurt themselves. Uneven driveways also can lead to wear and tear on your vehicle, as the tires and brakes have to work harder to traverse the uneven surfaces. If there’s a seam between the driveway and the street or garage, the bump of the car repeatedly driving over this seam can seriously damage the suspension.

There are numerous repair options for uneven driveways and sidewalks, including mudjacking or slab jacking. But those outdated procedures are time-consuming, expensive, and invasive. The best way to fix your uneven driveway and sidewalk is with professional polyurethane injections. Lightweight but durable polyurethane foam is injected underneath the sinking slabs to effectively lift and stabilize them. It is a quicker, less invasive, and more reliable and long-lasting solution to concrete issues.
