Frost Heaving

snow against foundation

In areas with cold winter climates, frost heaving can sometimes put enough pressure on foundation walls to make them fail.

When water turns to ice, its volume increases by about 9%. If wet soil experiences a deep freeze, the wedging or heaving force that results can be extremely powerful.

Frost heaving can put literally thousands of pounds of force against your foundation walls, causing cracks, bowing, and heaving.
