There are different types of cracks that can form in your foundation walls or concrete floor. The most common are shrinkage and settlement cracks, which may indicate damage. The size, shape, and location of the crack will determine if remediation is needed or if no action is necessary. In general, shrinkage cracks less than 1/16-inch wide may allow water entry but typically do not compromise the structural integrity of your home’s foundation. Settlement cracks are more complex and require further investigation, possibly with guidance from a professional waterproofing company like Wet Basement Resolutions.
