Expansive Soil Causing Heaving

Expansive soils swell when they absorb water and shrink when they dry out, creating upward pressure that pushes slabs and foundations out of alignment. This often leads to visible heaving, cracks, and structural distortion.

Expansive Soil Causing Heaving

What Is Expansive Soil?

Expansive soil contains clay minerals that absorb water and dramatically change volume. This can lift concrete slabs, damage flooring, and crack walls. The impact is especially severe in regions with seasonal moisture cycles or drought.

  • Interior slab heaving
  • Warped or lifted sidewalks and patios
  • Foundation cracks due to upward pressure
  • Repetitive damage during wet/dry transitions

Heaving May Indicate a Larger Soil Instability Problem

Repeated cycles of swelling and shrinking can compromise entire slab systems and even foundation walls. Timely diagnosis and treatment of expansive soil conditions are critical to long-term building health.

Recommended Solution

Soil Stabilization Treatment is designed to reduce the swell potential of clay soils, improving their load-bearing performance and reducing future movement.
