What Causes Concrete Settlement in Oak Lawn?

Oak Lawn’s dense, mixed soil composition and seasonal freeze-thaw cycles make it especially prone to uneven concrete. Common causes include:

Water erosion from heavy rainfall or poor drainage
Clay-rich soils that expand and contract with moisture changes
Frost heave during winter months
Tree roots disrupting the soil structure
Poor compaction beneath the original concrete pour

These conditions can create air pockets beneath the slab, eventually causing it to crack, sink, or become unstable.

Why Choose PolyLevel® Over Mudjacking?

Unlike traditional mudjacking, which relies on a heavy, messy cement slurry, PolyLevel® foam is injected through small holes and expands to gently lift the concrete from below. It’s lightweight, precise, and cures in just 15 minutes.

Benefits of PolyLevel® in Oak Lawn:

Walk on your slab within 30 minutes, drive on it within 4 hours
Less invasive than slab replacement or mudjacking
Waterproof and won’t erode over time
Tiny, clean injection holes
Lightweight foam that won’t stress the soil
Ideal for Oak Lawn’s freeze-thaw climate and older homes

Our Concrete Leveling Process

1. Inspection & Evaluation

We start with a detailed on-site inspection to evaluate the severity and cause of the uneven concrete.

2. Drill & Prep

We drill small access holes (less than a dime in size) into the slab for injection points.

3. Foam Injection (Polyjacking)

Polyurethane foam is injected beneath the slab, expanding to lift and level the concrete precisely.
