There are a few types of foundation cracks may develop over some time: settling, structural, and shrinkage or curing cracks in recently done cement.
Settling foundation cracks usually occur in a few years of new build structure or a house. It happens because of the ground around the new build is still not well packed. Cold weather and rainwater, snowmelts make ground harden over time. Those cracks are horizontal on the walls and have small gap width typically 1/16 inches to 1/8 inches.
Shrinkage or curing cracks in cement might develop if the foundation is poured concrete and as concrete cures, it might develop cracks if it didn't have cuts. Also, concrete needs a lot of water when it dries, other factors should be considered as well. Often cracks occur at corners of windows or doors. The shrinkage tends to pull concrete apart. This is more of an experience thing. So it is crucial that the company that does concrete for you knows how to make concrete foundations proper. We advise on getting references, online reviews, and even check for previous job sites to ensure quality.
Structural cracks are the one that should not be ignored and addressed promptly. They are usually longer and have gaps are wider. If you concerned about having basement foundation cracks, please call us to book a free consultation.
While nonstructural cracks are not dangerous to the structure of the house foundation, over time, they tend to expand and let water, gases, and soil to let in. Even if there is no water seepage through the crack, gases like radon that accumulates in the ground levels are dangerous to the health. Radon gas is the second leading cause of lung cancer.
For concrete, it is reasonable to develop cracks over time as it tends to expand and shrink with changes in temperature. However, unlike many competitors, we provide a warranty on concrete projects we perform.
