If you suspect issues with your home’s foundation, heaving could be the problem. We explain common causes of foundation heaving as well as the strategies we use to repair foundations and slabs.
What is Heaving?
Heaving happens when moisture or ice causes underlying soil to significantly expand and lift a foundation or slab upward. Soil may not seem like it can make a large impact, but the more moisture it holds, the stronger the force it can exert against your foundation. In fact, the International Association of Certified Home Inspectors states that “soils capable of damaging foundations may… exert as much as 5,500 pounds per square foot (psf) of pressure against the concrete.”
What Causes Heaving?
If your yard doesn’t drain properly, continuous or heavy precipitation can penetrate the soil beneath your home’s foundation. The soil can then expand and cause foundation damage. Your soil may also absorb excess moisture from any broken or leaking utility lines running under your foundation. Fixing these leaks ensures there won’t be unnecessary pressure against the foundation.
How Will I Know If I Have A Foundation Heave Problem?
You’ll know you have a foundation heave problem on your hands if:
- Your doors and windows stick
- Your floors and/or walls have cracks
- Your floors are uneven
Keep in mind that foundation heave and foundation settlement present similar signs, so when in doubt, contact your local basement waterproofing company. They’ll properly diagnose and correct any issues.
How Can You Repair Heaving Foundation Damage?
The experts’ priority will be to remove unwanted water wherever possible. One method we use to repair a heaving foundation is to stabilize the soil with a polymer injection. This injection helps soil build resistance against water. On the other hand, if the heave damage is severe, it may be necessary to drain your foundation or repair it entirely.
As soon as you notice heaving, you should have your local professionals take care of it right away. Contact the The Real Seal today with any additional questions about foundation heaving and whether this is the best option for your home.

Is it possible for a 80 wide by 200 feet slab heave all at once thank you
Hi Craig,
Yes, it is possible. With enough water pressure, even dams will break. There will need to be a lot of water pressure or earth heaving for it to happen, but it is possible. Did this happen to you? Do you have any pictures you can share?
