Hither in Canada, when winter comes, it's usually followed by a lot of snow. This year there hasn't been quite every bit much white stuff every bit usual, only a contempo freezing-rain storm got me thinking near foundations. I get a lot of questions and emails from concerned homeowners worrying about their foundations. They've found a cleft, they're concerned almost water getting in, and they desire to know what they can do to protect their homes from the inside and exterior.
With the spring melt just a few months away, I idea this would be a good opportunity to accost some of those questions.
Cracks in the Foundation
Non all cracks are serious. When concrete cures or dries, it tin can scissure, so if y'all've just laid a new foundation and see a few small cracks, don't call me simply yet. Marking them with tape, and cheque back in a few months, if they aren't growing, they can usually exist filled with an epoxy injection or an expandable foam. It's for this reason, I wouldn't recommend finishing a basement right away after a new foundation is placed. Allow your home go through a few wintertime seasons – so if whatever cracks do appear, they tin can be stock-still more than easily.

Whenever I'chiliad checking out a home, I like to conduct a small rubber ball with me. Why? Information technology offers a quick and easy way to test the grading of the driveway. But place the ball on the pavement and see which management it rolls – you want the driveway to be graded and so that the ball rolls away from the foundation. Information technology stands to reason that melt-water will flow in the same direction of the driveway.
Other Areas in Need of Attention
When the ground is frozen during the wintertime, excavating to repair any major bang-up isn't really an choice. So what can you exercise to protect your basement from water during the winter months? Beginning past taking care of your pipes. A frozen pipe can burst leading to water damage directly to your foundation.
