Can flooding cause foundation damage? Absolutely. In fact, foundations in wet ground almost always end up with cracks and other structural problems. Even if you don’t think you have lots of wet ground around your foundation, even a slight increase in moisture can prove dangerous.
There are many different types of flooding, and unfortunately, most of them can contribute to your foundation cracking. Whether through an act of nature or because of a plumbing problem, these types of water damage may seriously impact your home.
This type of flooding doesn’t happen inside your home; it happens on the outside. It may be because of a monsoon, a plumbing issue in the neighborhood, or just poor drainage in your area. Regardless of the reason, it’s going to mire your foundation in wet ground, which is never a good thing.
If the area around your home has been dealing with a lot of water recently, it’ll start sinking into the soil. That will make the soil expand and push against your foundation, creating extreme hydrostatic pressure that can easily lead to foundation cracks and water leaks.
Heavy snowfall can be a problem for foundations, but it’s not always for the reasons you might think. Many foundations can survive the extreme cold and even the weight of the snow. However, when heavy snow starts to melt, it creates excess flooding.
Similar to other excess flooding, snow melting can create lots of problems for your foundation. If your foundation has any existing cracks, even small ones, water will almost certainly find its way in. As the water starts to evaporate, this can lead to water damage not only in your foundation but in the rest of your home.
This type of flooding is almost exclusively internal. If you’re dealing with a plumbing leak, it’s very possible that the leak will end up traveling under your home or inside the walls, which is where most plumbing exists. Many plumbing leaks, then, end up leaking into your basement or crawl space area.
Sometimes, it can be even more difficult to catch foundation issues due to plumbing leaks because you may have to deal with much more visible problems first. If you have a plumbing issue, even if the water mostly impacted the inside of your home, it’s a good idea to schedule a foundation inspection to make sure it didn’t also create foundation problems.
