Any contractor will tell you, your home is only as secure as the foundation it stands on. This means that if your concrete foundation is starting to deteriorate, crack, or have other issues, the structural soundness of your house is also in danger. Most people know pretty well how to tell that their home is having foundation problems, whether it is cracks along corners or shifted window frames. However, many homeowners struggle to pinpoint the reasons why their concrete foundation became damaged to begin with. Understanding the cause of foundation problems is the key to avoiding future issues. Here is a brief glance at some of the lesser-known reasons for a concrete foundation to fail.
Cause: Extreme variations in ground temperature.
Variations in ground temperature from one extreme to the next causes the soil that supports your concrete foundation to shrink and expand as water content changes. You can usually spot signs of this by taking a look at the dirt surrounding the concrete. The soil may seem to be pulled away from the foundation at times and at some points may seem swelled against it. While this is hardly an issue you can control, knowing that this is an issue on your property will help you take the necessary steps to protect your foundation once it is repaired.
Cause: Excessive number of tree roots around the foundation.
Tree roots are pretty unavoidable if there are trees on your property, but they are hardly an issue unless there are many. If there are a huge number of trees, the excessive amount of roots beneath the ground can leach moisture content from the soil, which will also cause the ground to shrink. As the soil becomes more and more dehydrated, it can completely shift the geological makeup of the ground beneath your home, which will cause the foundation to shift as well.
Cause: Hidden drainage leaks.
Most people catch on when there is a drainage leak around the house, but this is not always the case if drainage lines run beneath the ground and also beneath the foundation of your home. Too much moisture allows the ground to change dramatically, both in density and structure. This drastic change in density and structure puts pressure on the concrete foundation at points where it would normally be stable. If you have drainage lines running beneath your home, it is always a good idea to do routine maintenance checks in the crawlspace to look for signs of leaks.
