The Problem:

Your foundation or slab floor is moving upwards, leading to cracks in the walls and floors of your home. This problem is generally known as slab heave or slab upheaval.

What Causes Foundation Heave?

Foundation heave occurs when there is an increase in moisture or freezing forces causing the upward movement of a foundation or slab. Foundation or slab floor moving upwards results in cracks in the walls and floors of your home. Slab and foundation heave is most commonly caused by forces such as expansive soils, frost heave, plumbing leaks, and heavy precipitation. 

Telltale Signs:

  • Cracking on inside walls (common)
  • Cracking on outside walls (rare)
  • Cracks on the concrete floor slab
  • Displaced or tilting slab sections

How to Fix It:


Solutions for slab heave can be as simple as repairing a plumbing leak under your foundation—or as extensive as demolishing and then reconstructing damaged sections of foundations or slabs.

What Causes Foundation Upheaval?

Heave is the upward movement of a foundation or slab caused by underlying soils that expand or swell. This occurs due to an increase in moisture or by freezing forces (frost heave). Heave is more common with slabs than foundations because slabs have less weight to resist heaving forces. Unless there is a long period of drought, heave most commonly occurs within the first few years of the building’s construction.

Slab and foundation heave are most commonly caused by these four force:

  • Expansive Soils
  • Frost Heave
  • Plumbing Leaks
  • Prolonged or Heavy Precipitation

What NOT To Do:

Before doing any repairs to your foundation, it’s important to identify the problem as heaving. Some contractors who have not been fully educated on the signs of heave can easily misread the cracks in your home and suggest the wrong solution. The problem? While heave is the opposite of foundation settlement, the symptoms are often similar. To an untrained eye, it may appear that the exterior walls are going down—when what’s really happening is that the basement slab is being pushed up near the center of the house. To apply the right solution to a foundation problem, make sure you’re getting the right diagnosis. More about sinking concrete slab floors.
