Why Is My Driveway Cracking? Causes of Settling Concrete and Solutions

A cracked driveway can be an eyesore, but more importantly, it can pose a tripping hazard and lead to further foundation problems.  If you're noticing cracks snaking across your once-smooth concrete, you're likely dealing with settling concrete. But what exactly causes concrete to settle?

Understanding the Culprits Behind Settling Concrete

Several factors can contribute to concrete settling and cracking:

  • Improper Soil Compaction: During installation, the soil beneath the concrete must be properly compacted to create a stable base. If the soil isn't compacted enough, it can settle over time, causing the concrete slab to sink and crack.
  • Soil Erosion: Water erosion beneath the driveway can wash away soil particles, leading to a loss of support and subsequent concrete settling.
  • Tree Root Growth: Tree roots can exert immense pressure on underground structures, including driveways. As roots grow and expand, they can push up and crack the concrete.
  • Freeze-Thaw Cycles: In climates with freezing temperatures, water that seeps into concrete can freeze and expand. This repeated freeze-thaw cycle can cause the concrete to crack and crumble.
  • Poor Drainage:  Improper drainage around your driveway allows water to pool and saturate the soil beneath the concrete. This saturated soil can lose its stability and cause the concrete to settle.

Don't Replace, Revive: Introducing Spray Foam Concrete Lifting

While replacing a cracked driveway might seem like the only solution, a more efficient and cost-effective option exists: spray foam concrete lifting. Here's how it works:

  1. Strategic Injection:  Small holes are drilled into the concrete at specific locations.
  2. Foam Injection:  A specially formulated polyurethane foam is injected through the holes.
  3. Lifting Power:  The foam expands rapidly, lifting the concrete back to its original level.
  4. Fast Curing:  The foam cures quickly, minimizing downtime for your driveway.
  5. Holes Sealed:  Once the concrete is level, the injection holes are sealed.
