What Is a Cracked Concrete Patio?

When a patio cracks, sinks, or pulls away from the house, the soil underneath has shifted and the slab is following it down. Foundation Crack Repair LLC repairs Long Island patios with modern foam injection and crack sealing techniques that get the slab back to level — without the cost and mess of full replacement.

A cracked concrete patio is any poured slab that has fractured, settled, or developed open joints because of stresses below or above it. Long Island patios deal with everything from saturated clay soil to root pressure to deck loads, and over time, even well-built patios show their age.

  • Cracked concrete
  • Sinking concrete slab
  • Concrete with pits, flakes, or stains
  • Cracked pool decks
  • Sunken porches
  • Sinking steps
  • Damaged sidewalks adjoining the patio
  • Cracked driveway near the patio

What Causes a Cracked, Uneven Patio?

Soil Settlement & Erosion

Shifting or eroding soil under the slab creates voids that the patio drops into over time.

Heavy Rain & Drainage Issues

Water that pools next to the patio washes out the soil under it.

Tree Roots

Roots from nearby trees lift, crack, and unsettle slabs without warning.

Freeze-Thaw Damage

During Long Island winters, water in cracks expands and breaks the slab apart from the inside out.

How to Fix a Cracked Concrete Patio

Most patios can be fixed in place with the right combination of soil stabilization and crack treatment:

Thorough Inspection

We figure out whether the slab dropped, lifted, or just cracked — the fix depends on the cause.

Polymer Foam Injection

We drill small ports and inject expanding foam to fill voids and lift the slab back to level.

Crack Repair

We seal active cracks with a flexible polymer that handles freeze-thaw cycling.

Surface Treatment

Where pitting and staining are an issue, we recommend sealing options to protect the surface going forward.
