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. 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 forces:
A house built on soils with high clay content will be susceptible to heaving forces because clay-rich soil expands significantly when it gets wet.
The excavation for a foundation often gives the soil around and under a house a chance to dry out and shrink, as shown in the photo at right. After the house is built, clay-rich soil that gets soaked during wet spells can cause heaving problems, while also damaging foundation walls.
Water increases in volume by nearly 10% when it freezes, and wet soil can expand even more when frozen. When wet soil freezes the resulting pressure can cause the slab or foundation wall to shift and crack.
The colder the temperature, the deeper the soil will freeze. Frost forces can lift a foundation dramatically – sometimes by several inches – leading to serious heave damage.
Leaks or breaks in plumbing lines that run underneath a concrete slab or through a foundation wall can deposit moisture underneath the foundation and slab. This moisture can be from supply lines, waste lines, or even your home’s HVAC system.
Over time, this moisture can cause the soils underneath the foundation to expand, which will then cause them to push up on the structure above.
Prolonged Or Heavy Precipitation
Too much precipitation combined with too little drainage away from the house will lead to increased moisture underneath your foundation. Moisture that comes into contact with expansive soil can result in heaving of your foundation and slabs.
Precipitation can also cause expansion in the soils on the sides of your foundation, leading to bowing, buckling walls.
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.
