Frost Heaving: How to Repair a Home Foundation Crack this Winter

Winter is coming but we have already felt some below freezing nights along with rain, snow and sleet. It may be fall, still, but it doesn’t feel like it. The nights in the Maryland/Washington, D.C. DMV area are only going to get colder.

In fact, meteorologists are calling for colder-than-normal temperatures this winter. So, brace up. Make sure your HVAC unit is working properly, you have salt packed away and there are no cracks in your home’s foundation.

Wait. You may ask what do cracks in my home’s foundation have to do with a frigid winter? It has a major affect. Frozen ground below your home causes dirt to heave and then contract. The “Heave Cycle”, as it is known, can cause your foundation to crack.

As the winter season goes on, daily exposure to ice and freezing temperatures can cause further damage to your home’s foundation. Three consecutive days of below-forty temperature may enlarge the cracks.

It all happens this way: Ice freezes beneath the concrete foundation. That is called “frost heave” where dirt moves from the formation of ice lenses (long crystals of ice). These same ice lenses can also cause a ground collapse, which can cause serious cracks and damage to the home foundation.

When the foundation starts slipping and cracking, this causes a domino affect in the home which we have discussed in previous blogs. Your foundation, floors, walls and other home structures will be affected. Then you will notice doors and windows not closing, stains on the walls and tilted cabinets.

Frost heave starts from the top as the soil freezes. The foundation never moves. In fact, it is locked as the ground freezes and pulls the foundation up. The soil then fills in the cracks in the foundation. Once the weather thaws, the foundation unlocks from the soil and settles. However, soil has been displaced under the foundation and when the home goes down, it is in a different location.

You can’t prevent cold weather, but you can prevent frost heave from damaging your home foundation any more in the future. Your licensed home foundation repair contractor can do the following:

  1. Drive the footing into the soil.
  2. A bell-shaped fitting is installed at the bottom of the footing to stop it from moving with the frost or other weather events.
  3. The concrete slab then has reinforcing steel installed.

Your holiday season has enough stress already not to be compounded by major home foundation problems. Contact your local licensed, home foundation repair contractor and have them inspect your home.
