How You Can Combat Frost Heave with Your Exterior Concrete

Know anyone who's interested in building a home? If you have any friends, family, or co-workers who are looking to own their first or second home - would you forward this message to them? We'll be happy to show them our 6 new construction home plans along with the benefits of owning a Charleston Home so they can make a decision that's right for them.

We've had a pretty cold winter, with a lot of temperature swings and moisture changes. This has caused many of our streets, sidewalks, and driveways to fall victim to what is known as "frost heave." This is when extreme cold temperatures and moisture get into the small cracks in the cement and cause the cement to rise. This happens every year, but this year in particular has caused a lot of extra frost heave.

Since temperatures have risen here in the last few weeks, the cement has returned to its original position, but it has left behind some imperfections that you'll need to shore up. After frost heave happens, you tend to see a lot of little hairline cracks that will start to form in the cement - seal those up once temperatures get above 50 degrees.

Your home may have this problem as well. On many driveways, between the driveway and the garage, there is an expansion joint. The joint is meant to be there so the driveway can't be pushed into the house. When frost heave occurs, it will be pushed up. You can't really push it back down, so the best thing to do in this situation is to try to cut off the excess expansion joint safely with a knife. Then, get some polyurethane sealant and apply it to the crack. Doing this sooner than later will help prevent against frost heave next winter.

If you have any questions, you can always give us a call or send us an email. We look forward to hearing from you!
