The Top Common Causes of Foundation Cracks and Basement Leaks (and How to Fix Them!)

Cracks in building foundation.

Having a home is a great feeling, but it also comes with great responsibility. Homeowners must play their part to ensure proper house maintenance, but sometimes, even when the utmost care is taken, things can go wrong. Foundation cracks and basement leaks are two things that commonly occur in many homes. These issues can be a major inconvenience, especially if they happen unexpectedly, and the root cause is not immediately clear.

Today we'll examine some common causes of basement leaks and foundation cracks, how to remedy them, and when it might be time to call in the pros.

1. Issues With Soil


If the soil surrounding your home has a high clay content, then it's possible that it can shift and expand over time due to the presence of moisture, which can cause cracks in your foundation especially in block foundations it is important to waterproof block foundation and also install Styrofoam to protect from frost.


2. Foundation Construction

If you're experiencing cracks in your foundation accompanied by leaks, the issue may be with the foundation itself and the way it was built


3. Plumbing Leaks

Cracks and leaks in your home foundation could be a telltale sign that you have a leak somewhere in your plumbing system. If water or moisture escapes from a plumbing line, it then seeps out into the ground around the foundation, which can cause cracks to appear and moisture to seep through.


4. Frost Heaving

In Ottawa, to say the winters can be cold is an understatement. In areas that experience cold weather, the ground around a home can often freeze. The freezing and thawing process can cause a shift underneath your home basement, which in turn can cause cracks.


5. Settlement

Cracking can also sometimes occur as the concrete footings of your foundation settle into the ground. This usually happens when the soil underneath has become unstable. This can potentially be a serious issue. If you think you can see signs of foundation settlement in your basement, you may need to contact a professional for a full appraisal of the situation.


What to Do When You Spot Foundation Cracks


Depending on what is causing them, foundation cracks could be somewhat benign or a sign of a much larger problem. In any case, cracks can lead to water damage, invasive pests, and further structural issues, so they are best taken care of right away.

When it comes to foundation cracks, you should use your best judgment about the most prudent course of action. Often, with hairline cracks, it's possible to have them injected with polyurethane.

However, it can be hard to tell when a crack is harmless or when it could be a symptom of something much worse. That's why if you're in any doubt, it's always smart to call a professional for a second opinion.
