Discover how A-1’s patented stone slurry grout leveling process lifts sunken slabs using expert control.
When concrete slabs start to settle, tilt, or sink, it’s time to bring them back in line. At A-1 Concrete Leveling, we’ve spent over 30 years perfecting a concrete leveling technique that lifts sunken slabs to improve curb appeal and safety.
In this article, we’ll walk you through the patented A-1 concrete leveling process using our stone slurry grout method. We’ll also highlight what makes it different (hint: control!) from other methods like foam leveling or mudjacking.
Why Control Matters in Concrete Leveling
It may seem like brute force is what lifts concrete, but slow, controlled lifting is actually the key to precise concrete leveling.
Without a careful approach, leveling can leave behind problems like:
- Partially filled voids, which allow slabs to resettle later.
- Pillars of material, where only parts of the slab are supported, leading to cracks or resettling.
- Over-lifted slabs, which can’t be brought back down once they’ve risen too far.
That’s why A-1’s system was designed for slow and steady lifting, with maximum control at every step.
Step-by-Step: How the A-1 Stone Slurry Grout Leveling Process Works
Step 1: Drill Small, Strategic Holes
Once you approve your estimate, an A-1 crew comes out to address your uneven concrete. They begin by drilling ⅝″ - 1″ holes in the settled slabs so the limestone slurry can be pumped underneath.
*Note: In some cases, A-1 technicians may recommend foam concrete leveling, which is different from our patented limestone slurry grout leveling process.
Step 2: Pump It Up
The star of the show? Our all-natural limestone slurry. This eco-friendly blend is pumped beneath the slab at a low pressure and speed. Why?
Because gradual lifting is stronger, safer, and smarter.
Our patented pump system lets us adjust the material thickness on the fly so we can match the right lift force to the needs of each unique situation.
Step 3: Patch Drill Holes
After your concrete is lifted back up to the right spot, the drill holes are patched with non-shrink grout, blended in with the concrete, and left to cure.
Step 4: Clean and Enjoy
The all-natural and environmentally friendly limestone slurry is sprayed off, and your concrete is ready to enjoy.
The A-1 Concrete Leveling system is all self-contained aboard a mid-size truck that doesn’t disturb landscaping or lawns and won’t harm driveways, making cleanup a breeze.
What Makes A-1’s Method Different?
You’ve got options when it comes to leveling, so why go with A-1’s patented stone slurry grout process? Let’s compare:
| Feature | Stone Slurry Grout Leveling | Foam Concrete Leveling | Mudjacking |
|---|---|---|---|
| Lift Control | High | Lower (can expand unpredictably) | Lower (high pressure) |
| Drill Hole Size | ⅝″ to 1″ (medium) | ⅝″ (small) | 2″ (large) |
| Material |
Eco-friendly and locally sourced limestone |
Petroleum-based foam |
Sand/soil slurry |
|
Cost |
Mid-range |
Highest |
Lowest |
The secret sauce is control. Our ability to customize the slurry mix and pumping pressure in real time means we avoid the “pancake stack” effect that can weaken repairs done with foam or mudjacking.
Pro Tip: Foam concrete leveling and mudjacking can still be effective, durable solutions when done correctly and properly maintained. Read more about each method compared side-by-side.
Is Stone Slurry Grout Leveling Right for You?
If your concrete is mostly intact but uneven, and you want a repair that:
- Supports your slab fully from underneath
- Minimizes risk of cracking and over-lifting
- Uses natural, eco-friendly materials
...then our stone slurry grout process might just be your concrete’s best friend.

Maintenance Makes All the Difference
Want your leveling repair to last? Pair it with our concrete cleaning, sealing, and caulking services. Caulking cracks and joints helps prevent water from sneaking under the slab and causing the concrete to resettle.
