Crawlspace Foundation Cracks
There is no such thing as a perfect foundation. Acrawlspace foundation is made up of concrete and there are two rules that every contractor knows about concrete, it hardens and it cracks. It is almost guaranteed to do both. Concrete and block foundations usually have at least a few cracks. The key is recognizing which are insignificant and which are serious. The mistake is ignoring any cracks!
After construction and over a period of time, your home’s foundation will shift and settle into position. Poor soil conditions, changing seasons, and moisture content in the soil will stress your crawlspace foundation. Small and large cracks in the crawlspace foundation will appear and are usually a sign of some type of foundation settlement. It is important to know what to look for.
Signs to Look For:
1. Stair-Step Cracks - Stair step cracks in cinder block walls and brick is one of the most common settlement signs in a crawlspace foundation. Since these cracks are always a sign of settlement or upheaval, they must be addressed immediately before further damage occurs.
2. Vertical Cracks – Vertical or nearly vertical cracks in poured concrete or concrete block crawlspace foundations are bad news. If the cracks are wide at the top, it usually means that one end or both ends of the foundation are sinking. If the crack is wider at the bottom, then the settlement is occurring at the bottom of the crack.
3. Horizontal Cracks – Cracks that run horizontally along the middle of a block wall in a crawlspace are rare. It is a more common problem with basements. Horizontal cracks are sign that the pressure of the dirt behind them has bowed the wall and the crack is the hinge point.
4. Door, Window, and Garage Separation – Look for separation of the trim, siding, or brick from the doors and windows. While this could be caused by structural problems, it is most often attributed to the foundation sinking.
5. Drywall & Trim Cracks – Drywall cracks above doorways & windows, in ceilings, and in corners are all signs of settlement. Crown Molding, Door Trim, and Baseboards that have separated are sometimes signs of foundation failure as well.
6. Shrinkage Cracks – A newly poured crawlspace foundation wall may contain small cracks as it cures. Fortunately, shrinkage cracks are insignificant. The cracks are less than 1/8 inch wide, vertical, and usually in the middle of the wall. Call a professional to ensure you are only dealing with these cracks.
