Are Cracks in Concrete Slabs Normal?

If you’ve noticed cracks in your concrete driveway, patio, or basement floor, you’re not alone—and you’ve come to the right place. Cracked concrete is a common concern, but not all cracks are created equal. Let’s talk about why cracks happen, when you should be concerned, and how our polyurethane foam lifting can restore your slabs to their original glory.

Concrete is durable, but even the toughest materials aren’t immune to a little wear and tear. Cracks can occur for several reasons:



1. Shrinkage: As concrete cures, it shrinks slightly. This natural process can lead to hairline cracks that are usually cosmetic.
2. Soil Movement: In New Jersey, Westchester, and the Lower Hudson Valley, fluctuating soil conditions are a big culprit. Expanding or settling soil beneath your slab can cause it to shift and crack.
3. Temperature Changes: Concrete expands and contracts with temperature swings. Over time, this can create stress cracks.
4. Heavy Loads: Driveways and garage floors take on significant weight. Overloading can lead to cracks, especially if the slab wasn’t properly reinforced.

When Are Cracks in Concrete Slabs a Problem?

Not all cracks spell trouble. Small hairline cracks or those less than 1/8 inch wide are generally harmless. But larger cracks, uneven slabs, or signs of sinking could indicate underlying issues that need attention.

Here are some signs that a crack needs professional help:

• The slab is uneven or one side has sunk lower.
• Cracks are growing or widening over time.
• Water pools in or around the cracks.
• There’s evidence of soil erosion or voids beneath the slab.



If you’re dealing with these issues, don’t wait. Left unaddressed, they can worsen and lead to more costly repairs.

Our Solution: Polyurethane Foam Lifting

At Metro Concrete Lifting, we specialize in a game-changing solution called polyurethane foam lifting. Unlike traditional mudjacking or slab replacement, this modern method offers fast, effective results with minimal disruption.

Here’s how it works:

1. Assessment: Our team inspects the slab to identify the root cause of the cracking or sinking.
2. Precision Drilling: We drill small holes (about the size of a dime) into the affected slab.
3. Foam Injection: Polyurethane foam is injected into the voids beneath the slab. It expands, lifting the concrete back into place and filling gaps in the soil for added stability.
4. Finish: Once the slab is level, we patch the holes and clean up, leaving your space looking great!

This process is quick—most jobs are completed in a single day—and eco-friendly. Plus, polyurethane foam is lightweight yet strong, preventing further sinking without adding strain to the soil.
