The Basics of Concrete Foundation Repair

As a piece of exposed concrete ages, it may become cracked or pitted due to various causes. When that piece of concrete is the foundation for a structure, the entire structure becomes endangered and compromised.

The main culprit behind cracks in concrete foundations is water. Water will always find the lowest and easiest path for it to travel. If that path is beside a concrete foundation, that foundation is in trouble. The cracks may be just the width of a hair at first, but often they will widen over time. The method for concrete foundation repair that has been subjected to water damage can be costly. If the leak is localized to one spot it may be possible to dig just in that area and patch it with a waterproof barrier over a new patch of concrete. If there are multiple leaks, extensive excavation may be required.

Though water is usually the main cause for damage, other factors may come into play. The dirt surrounding the foundation may lose some of its moisture content, reducing the pressure exerted on the foundation, allowing the structure to buckle outward. Roots may also cause a problem. The cost for concrete foundation repair of this type can be just as expensive as that from water damage, perhaps more. Trees have enormous strength and tenacity. If your foundation stands it the way, you will probably have to pay.

If you catch the problem early (and you are lucky), you may be able to do the concrete foundation repair yourself. First, it is necessary to clean the affected area. Use a wire brush or some other abrasive material to remove any loose chips of concrete. Then you should thoroughly dry the concrete. Set up a large fan near the area to expedite the process. This may take a while, as concrete has the ability to retain large amounts of moisture. Then repair the area with concrete or a concrete and caulk mixture. Finally, cover the area with a waterproof sealant.
