Uneven Concrete? Here's How PolyLevel Lifts and Levels It the Smart Way

If you’ve noticed your driveway, sidewalk, patio, or pool deck starting to sink or crack, you’re not alone. Uneven concrete is a common issue for homeowners, especially after years of rain, erosion, and seasonal changes. What many people don’t realize is that sinking concrete isn’t just unsightly, it can also become a tripping hazard, lead to water pooling, and even affect your home’s value. At Quality 1st Basement Systems, we use our PolyLevel Concrete Lifting and Leveling System: a modern, long-lasting alternative to traditional mudjacking that restores your concrete safely and efficiently.

Why Concrete Sinks

Concrete slabs rely on the soil beneath them for support. Over time, that soil can shift, wash out, or compact, leaving empty spaces (voids) beneath the slab. Without that support, the concrete begins to sink and crack.

Common causes include:

• Erosion from rain and water runoff

• Poorly compacted fill soil after construction

• Freeze-thaw cycles that expand and contract the ground

• Soil shrinkage during dry, hot weather

Once the soil settles or weakens, the concrete above it loses stability, and that’s when uneven surfaces appear.

The PolyLevel Solution

PolyLevel is a lightweight, expanding polyurethane foam that lifts and levels concrete back to its original position with far greater precision and durability than traditional repair methods.

Here’s how it works:

1. Our team drills small, penny-sized holes into the sunken concrete slab.

2. We inject the PolyLevel foam beneath the slab, where it expands to fill the voids and gently lifts the concrete.

3. Once the slab is leveled, the holes are patched, and your concrete is ready to use (often within just 15 minutes!)

Why PolyLevel Is Better Than Mudjacking

Traditional mudjacking uses a heavy mixture of concrete and mud that can cause further settling over time. PolyLevel offers a cleaner, longer-lasting solution.

Advantages of PolyLevel:

• Lightweight: Won’t add extra weight to weak soil

• Quick cure time: Ready to use in about 15 minutes

• Waterproof: Won’t wash out or erode over time

• Precise lift: Expands evenly for smooth, level results

• Long-lasting: Permanent, durable support for your slabs

PolyLevel is not just a fix, it’s a smart investment in the safety and appearance of your property.

Where We Use PolyLevel

This system works on a variety of surfaces around your home, including:

• Driveways

• Sidewalks and walkways

• Garage floors

• Pool decks

• Patios and porches

• Interior slabs

If it’s concrete, PolyLevel can lift it.

Why Now Is the Best Time to Fix It

Fall is an excellent time to repair uneven concrete before winter weather makes things worse. When water seeps into cracks and freezes, it expands and causes even more damage. By leveling your concrete now, you’ll protect your slabs, prevent further sinking, and improve your home’s safety before the cold sets in.
