Is Your Concrete Sinking? Here’s What You Need to Know About PolyLevel®

Concrete around your home should be safe, level, and long-lasting. Unfortunately, many homeowners notice their driveways, sidewalks, or patios start to sink or crack over time. Not only does this create an eyesore, but it can also lead to safety hazards and costly damage if left untreated.

At Lowcountry Foundation Repair, we use an innovative product called PolyLevel® to lift and stabilize sunken concrete. Here’s what you need to know about the signs, causes, and solutions for sinking concrete.

Signs of Sinking Concrete

If you’ve spotted any of these issues, it may be time to take action:

• Uneven or sloping surfaces – Patios or pool decks that feel tilted.

• Cracks in the slab – Small gaps that keep widening over time.

• Tripping hazards – Sidewalks or steps that are no longer level with each other.

• Pooling water – Puddles forming on driveways or walkways after rain.

• Doors or gates sticking – Shifts in surrounding concrete can throw off alignment.

What Causes Concrete to Sink?

Several factors can cause concrete slabs to settle and shift:

• Soil washout – Water washes away the soil underneath, leaving gaps.

• Poor compaction – If the soil wasn’t compacted properly during construction, it may settle over time.

• Erosion – Drainage issues and heavy rainfall can erode the base beneath your concrete.

• Shrink-swell soils – Certain types of soil expand and contract with moisture changes, moving the slab above.

The PolyLevel® Solution

Traditional fixes like mudjacking or full slab replacement can be messy, invasive, and expensive. PolyLevel® offers a smarter alternative.

Here’s how it works:

1. Small injection holes are drilled into the affected slab.

2. High-density polyurethane foam is injected beneath the concrete.

3. The foam expands, filling voids and lifting the slab back into place.

4. The holes are patched, and within minutes the area is ready for use.

Why Homeowners Choose PolyLevel®:

• Quick & Clean – Minimal disruption compared to replacement.

• Lightweight – Won’t add pressure to already weak soil.

• Durable – Long-lasting stability you can rely on.

• Fast Cure Time – Driveways and walkways are ready to use within hours.

Take Action Before It Gets Worse

The longer sinking concrete goes untreated, the bigger the problem becomes. Cracks widen, trip hazards grow, and water damage spreads. With PolyLevel®, you can restore your concrete quickly, affordably, and permanently.
