By The Waterproof Group | Marietta, GA | Serving All Metro Atlanta
If you’ve noticed your driveway sinking, your sidewalk tilting, or your patio slab cracking and settling, you’re not alone. In Metro Atlanta—especially around Marietta and Cobb County—sunken concrete is incredibly common. Our red clay-heavy soils, seasonal moisture swings, and years of normal wear can cause the ground beneath concrete to shift or wash out. The result: uneven slabs that are not only an eyesore, but also a safety hazard.
At The Waterproof Group in Marietta, GA, we help homeowners across the Metro Atlanta area solve these issues with professional concrete lifting and long-term foundation repair solutions. In many cases, lifting and leveling concrete is faster, cleaner, and more cost-effective than tearing it out and pouring new slabs.
Below, we’ll explain what causes concrete to sink, how concrete lifting works, and when it’s time to call a local foundation repair company you can trust.
What Is Concrete Lifting?
Concrete lifting (also called slab lifting or concrete leveling) is a process used to raise and stabilize sunken concrete slabs. Instead of removing your existing concrete, we lift the slab back toward its original position by filling voids and stabilizing the soil beneath it.
Concrete lifting is commonly used for:
- Driveway leveling
- Sidewalk lifting
- Patio and pool deck leveling
- Garage floor lifting
- Porch and stoop lifting
- Warehouse and commercial slab leveling
The goal is simple: restore function, improve appearance, and reduce trip hazards—without the mess and expense of replacement.
Why Concrete Sinks in Marietta and Metro Atlanta
Concrete doesn’t “wear out” overnight. Most sinking slabs are caused by changes in the soil underneath the concrete. In our area, these are the most common culprits:
1) Expansive Clay Soil
Metro Atlanta soil often contains red clay that expands when wet and shrinks when dry. Over time, that movement can create voids beneath slabs or shift the base enough for concrete to settle unevenly.
2) Poor Drainage and Soil Washout
Downspouts dumping water next to a driveway, pooling near a patio, or a grading issue around the home can wash out soil. When soil erodes, the concrete above loses support and begins to drop.
3) Soil Compaction Issues
If the ground under the slab wasn’t properly compacted during construction, it can settle gradually. This is common with newer homes where soil was disturbed during building and didn’t fully stabilize.
4) Tree Roots and Organic Material
As organic material decomposes, it leaves empty space in the soil. Tree roots can also shift soil and contribute to uneven slabs.
5) Plumbing Leaks Under Slabs
A hidden leak beneath a slab can soften soil, cause erosion, and lead to rapid settling. This is one reason sinking concrete shouldn’t be ignored—sometimes it’s the first sign of a bigger issue.
Signs You May Need Concrete Lifting
Not sure if your slab needs lifting? Here are clear warning signs:
- Uneven or tilted sidewalks and walkways
- Cracks that widen over time
- Water pooling near a sunken driveway or patio
- A garage floor that slopes or feels uneven
- Gaps forming between a slab and the foundation
- Trip hazards along joints or edges
- Steps or porches pulling away from the home
If you notice any of these around your home in Marietta or anywhere in Metro Atlanta, it’s worth having a professional evaluation.
Concrete Lifting vs. Replacement: Which Is Better?
Many homeowners assume replacement is the only solution. In reality, concrete lifting can often deliver similar results with less disruption.
Benefits of Concrete Lifting:
- More affordable than demo and replacement in many cases
- Faster turnaround (often completed the same day)
- Minimal mess compared to removal and re-pour
- Preserves existing concrete so you keep the same look and finish
- Improves safety by eliminating trip hazards
- Supports drainage by restoring proper slope away from the home
Replacement can still be the right call when concrete is severely crumbled, structurally broken, or beyond repair—but many sinking slabs can be lifted successfully.
How Concrete Lifting Works
While methods vary by project, concrete lifting generally follows a reliable process:
- Inspection and Diagnosis
We identify why the slab sank, locate voids, and evaluate whether lifting is appropriate. If we see signs of broader foundation movement, we’ll discuss that too—because lifting concrete without addressing the cause can lead to repeat issues. - Precision Lifting Plan
We determine the best lifting points to raise the slab evenly and safely, minimizing stress on the concrete. - Void Filling and Leveling
Material is injected beneath the slab to fill empty spaces and lift the concrete. This stabilizes the base and helps prevent future settling. - Final Grading and Cleanup
Once leveled, we ensure the slab sits properly, the transitions are smooth, and drainage slopes make sense for your property.
How Concrete Lifting Connects to Foundation Repair
Sinking concrete isn’t always just a surface problem. Sometimes it’s related to underlying soil movement that can also impact a home’s foundation. That’s why working with a company that understands both concrete lifting and foundation repair matters.
At The Waterproof Group, we look at the full picture—because in Metro Atlanta, drainage issues and soil instability can affect:
- Driveways and sidewalks
- Porches and stoops
- Garage floors

In other words: concrete lifting can be a standalone repair, or it can be part of a larger plan to stabilize your home.
