Winter Freeze: Thaw Cycles and Their Impact on Foundations
When winter settles in, homeowners—particularly in the Northeast and Midwest—face a silent threat to their property’s structural integrity: the freeze-thaw cycle. This natural phenomenon can wreak havoc on your home’s foundation, potentially leading to costly repairs if left unchecked.
Don’t let your home succumb to Old Man Winter’s wrath. Learn more about freezing and thawing, how freeze-thaw cycles affect your home, and how Groundworks can help repair and protect your investment.
Understanding the Freeze-Thaw Cycle
The freeze-thaw cycle occurs when temperatures fluctuate between freezing and above freezing. Here’s how it works:
- Water in the soil around your foundation from rain or snow freezes as temperatures drop below 32°F.
- As temperatures rise, the frozen water thaws.
- This cycle repeats throughout the winter season.
The cycle ends in springtime. If you live in a particularly snowy area, you can expect one last major snowmelt.
How Freezing and Thawing Impacts Your Home’s Foundation
The freeze-thaw cycle can cause several issues for your home’s foundation, including:
- Soil Expansion and Contraction: As water freezes, it expands, pushing against your foundation. When it thaws, the soil contracts, potentially leaving gaps.
- Cracks and Fissures: The constant pressure from expanding ice can create or worsen existing cracks in your foundation.
- Water Infiltration: As the ice melts, it can seep into these newly formed or expanded cracks, leading to moisture issues in your basement or crawl space. Water can also seep inside through porous concrete walls, expand when it freezes, and create internal tension.
- Structural Instability: Over time, repeated freeze-thaw cycles can cause your foundation to shift, leading to more severe structural problems.
Signs of Freeze-Thaw Damage
When freezing and thawing begin to impact your home, you’ll notice these warning signs:
- Cracks in foundation walls or floor
- Bowing basement walls
- Doors or windows that stick or won’t close properly
- Uneven or sloping floors
- Gaps between walls and floors or ceilings
- Moisture or water in the basement or crawl space
7 Ways to Prevent Freeze-Thaw Damage to Your Foundation
While the freeze-thaw cycle is a natural occurrence, you can take several steps to minimize its impact on your home’s foundation:
1. Improve Exterior Drainage
Ensure water flows away from your foundation. This includes regularly cleaning and maintaining gutters to prevent overflow and extending downspouts at least 10 feet away from your home. You should also grade the soil around your foundation to slope away from the house.
2. Insulate Your Foundation
Proper insulation can help maintain a more consistent temperature around your foundation. Insulate the crawl space or basement walls and consider encapsulating the crawl space with a vapor barrier to control moisture.
3. Invest in Professional Waterproofing
Consider investing in professional foundation waterproofing services, including interior drainage and a sump pump system, to create a barrier against water infiltration.
4. Manage Moisture
Reduce the amount of water in the soil around your foundation by installing systems like a French drain to redirect groundwater. Moving inside, use a dehumidifier in your basement or crawl space to control indoor humidity.
5. Maintain Consistent Soil Moisture
Avoid extreme changes in soil moisture content by watering your foundation during dry spells (but not excessively). Avoid planting water-hungry vegetation close to your foundation.
6. Seal Cracks Promptly
Address any existing cracks in your foundation walls or floor as soon as you notice them. Use appropriate sealants for small cracks and consult professionals for larger or structural cracks.
7. Schedule Regular Inspections
Schedule annual foundation inspections, especially before and after winter. This allows you to catch potential issues early before they become major problems and address any vulnerabilities before the freeze-thaw cycle begins.
Implementing these preventative measures can significantly reduce the risk of freeze-thaw damage to your foundation. However, it’s important to remember that every home is unique, and what works for one may not be sufficient for another. That’s why consulting with foundation experts who can assess your situation and recommend tailored solutions is crucial.
How Groundworks Repairs and Protects Your Foundation
Along with basement waterproofing and crawl space encapsulation solutions, Groundworks installs customized foundation repair solutions that permanently stabilize and protect your home. Depending on the extent of the damage and its location, we may recommend some of the following repairs:
Wall Repair Methods
Walls that succumb to hydrostatic pressure from continuous freezing and thawing result in cracks and inward bowing. Carbon fiber straps stabilize walls with minor damage, and wall anchors and wall braces can potentially repair walls over time.
Foundation Piers
Foundation settlement requires another set of tools: foundation piers. Our three varieties—helical piers, push piers, and slab piers—permanently stabilize settling foundations and can help lift them back to the proper position.
Crawl Space Supports
We install durable crawl space support jacks for sagging and uneven floors that need a boost. Manufactured to withstand crawl space conditions, these adjustable supports permanently reinforce floors and can potentially lift them.

Freeze-Thaw Cycle FAQs
While many types of foundation damage repair are not covered by homeowner’s insurance, coverage varies by policy. Check with your insurance provider for specific details about your policy and coverage.
While issues that appear minor on the surface might seem to be DIY-friendly, foundation repair can be a complex process. It’s best to consult professionals like Groundworks for structural foundation problems, ensuring accurate diagnosis and lasting repairs.
It’s a good idea to get a foundation inspection every couple of years, especially if you notice damage. If you work with Groundworks to repair your foundation, you can take advantage of annual service and maintenance programs that include evaluations of your home and any repair solutions installed.
