Foundation cracks can be a source of worry for many homeowners. A crack in your foundation can cause a wide range of structural issues, from water damage to mold growth. Even a small crack can cause a lot of damage if left unchecked, so it’s important to understand the causes, types, and repair solutions of foundation cracks.

Causes of Foundation Cracks

Foundation cracks can be caused by a variety of factors. The most common are settling and soil movement. As your home settles, it puts pressure on the foundation, which can cause cracks to form. Soil movement can also cause the foundation to shift, leading to cracks. Other causes of foundation cracks include poor construction, poor drainage, and plumbing leaks.

It’s important to be aware of the possible causes of foundation cracks so you can take steps to prevent them. The best way to prevent foundation cracks is to ensure that your home’s foundation is built properly and that it has ample drainage to prevent water from pooling around it.

Types of Foundation Cracks

There are two main types of foundation cracks: vertical and horizontal. Vertical cracks are the most common and often appear when the foundation settles or shifts. They generally run from the top of the foundation to the bottom. Horizontal cracks are less common and usually indicate a major shift or settlement problem.

It’s important to note that not all foundation cracks are cause for concern. Hairline cracks may be normal, especially in older homes. However, any crack that is wider than 1/4 inch could indicate a problem and should be inspected by a professional.

Repair Solutions

If you find a crack in your foundation, the best thing to do is to have it inspected by a professional. The type of repair solution you need will depend on the type and size of the crack. For minor cracks, repairs can be done with epoxy or polyurethane injection. For major cracks, you may need to install a foundation pier or wall anchor.

It’s also important to keep an eye out for signs of water damage. If the crack is leaking water, you’ll need to have it repaired as soon as possible. You may also need to install a drainage system to prevent water from pooling around the foundation.

Preventative Maintenance

It’s important to be proactive about foundation cracks. Regularly inspect your home’s foundation for signs of shifting or settling, and be sure to address any minor cracks you find before they become major problems. You should also have a professional inspect your foundation every few years.

It’s also wise to invest in preventative maintenance. A professional waterproofing service, such as Perma-Dry Waterproofing, can help protect your foundation from water damage and can help you maintain its structural integrity.
