What Causes Uneven Concrete? Common Issues Columbus Homeowners Face

Why Uneven Concrete is More Than Just a Cosmetic Issue

Ignoring uneven concrete can lead to bigger problems down the line. It’s not just about appearances; it’s about the safety and integrity of your home’s exterior.

Common Causes of Uneven Concrete in Columbus

If you’re asking, “Why is my concrete uneven?”—you’re not alone. The unique climate and soil conditions in the Columbus area contribute to several common culprits:

1. Soil Erosion Beneath the Slab

Over time, water can wash away the soil that supports your concrete slab. Without this stable base, the concrete begins to shift and sink. This is especially prevalent in Columbus due to:

• Heavy rainfall: Columbus experiences an average of around 40-45 inches of precipitation annually, with heavier rainfall periods that can saturate the soil.
• Poor drainage: Inadequate grading or clogged gutters can direct water towards concrete slabs, exacerbating erosion.
• Runoff from downspouts: If downspouts aren’t properly extended, water can dump directly onto the soil next to your concrete.

2. Freeze-Thaw Cycles

Ohio winters are notoriously tough on concrete. Water seeps into tiny cracks and pores within the concrete. When temperatures drop below freezing (Columbus experiences nearly 100 days a year with temperatures below 32°F), this trapped water freezes and expands, putting immense pressure on the slab and causing it to heave or crack. 

When it thaws, the concrete often settles back down in a new, uneven position, repeating the cycle and worsening the problem.

3. Poor Soil Compaction

During installation, if the soil beneath your concrete wasn’t properly compacted, it remains loose. 

Over time, under the weight of the concrete itself, and the added pressure from vehicles or foot traffic, this loose soil can compress unevenly. This compression leads to settling and sinking of the concrete above.

4. Tree Root Intrusion

While trees add beauty and shade to your property, their expansive root systems can pose a threat to nearby concrete. 

As roots grow and seek moisture, they can spread underneath driveways, sidewalks, and patios, lifting the concrete from below and creating frustratingly uneven surfaces.

What Happens If You Ignore Uneven Concrete?

Sinking concrete might not seem urgent, but here’s why timely repair matters for your Columbus home:

• Tripping hazards: Uneven surfaces are a significant safety concern, posing a tripping risk for your family, guests, and anyone walking on your property.
• Water pooling and foundation issues: Sinking concrete can create low spots where water collects. This pooling water can then seep into your foundation, leading to serious and costly water intrusion issues in your basement or crawl space.
• Accelerated deterioration: What starts as a minor crack can quickly worsen when left unaddressed. Uneven concrete is more susceptible to further cracking and crumbling, making future repairs more extensive and expensive.
• Lower curb appeal and home value: Cracked, uneven concrete detracts from your home’s appearance and can significantly reduce its curb appeal and overall market value.

How SmartLevel Repairs Uneven Concrete in Columbus

At SmartLevel, we understand the specific challenges Columbus homeowners face with uneven concrete. We use a proven, state-of-the-art method called PolyLevel® concrete leveling, which lifts sunken slabs quickly and effectively with minimal disruption to your property.

Why PolyLevel® Works:

• Non-invasive application: The process requires only small, penny-sized holes drilled into the concrete, meaning no major excavation or demolition is needed.
• Waterproof and stable: Unlike traditional mudjacking, PolyLevel® foam is waterproof and won’t wash away or shrink over time, providing a long-lasting and stable solution.

PolyLevel® solves the underlying cause—not just the symptom—of uneven concrete. It’s an ideal solution for:
