Shrinkage cracks and in some cases other foundation cracks such as those caused by minor initial settlement might not be a structural concern but may still form an opening leading to water leaks into the building. Concrete shrinks as a natural process of it curing. This shrinkage causes the concrete to develop stresses and to relieve it, the basement wall cracks.
Once concrete cracks in a basement or crawl space wall or floor slab, it is possible for water to leak into a building through the crack. There are several ways to repair a basement crack leak. An easy, quick, and effective measure to stop basement or crawl space water entry through a foundation crack is to perform an injection of polyurethane foam into the basement crack. [Also be sure to find and fix the sources of water outside.]
The polyurethane foam forms a strong bond to the concrete. This bond will be able to withstand the hydrostatic pressure that may develop from high subsurface water levels. High underground or "subsurface" water levels are typically caused by heavy rains and most-often by failure to direct roof runoff or nearby surface runoff away from the building. This concrete crack repair process using polyurethane injection is likely to be more successful and more durable than other crack patching methods. Surface patching of the crack is just that. Only the inside of the basement wall is covered by a repair. Chiseling out the crack and filling it with hydraulic cement only fills a portion of the crack. Water can still enter the basement crack and will eventually force out the patch or hydraulic cement. [Forces that tend to cause separation of poorly-bonded concrete surface patches include the molecular action of crystallizing mineral salts left behind as moisture passes through the masonry wall.] Basement crack injection is a quick repair process that stops water leaks. The technician does not have to drill into the concrete to do it. For this reason the basement crack repair is a clean process. The technician will attach ports to the surface of the basement crack that allow the liquid polyurethane to enter the basement wall and stop the leak. Once the basement wall crack is completed, water will not be able to leak into the basement. Now the homeowner's possessions will be safe. As will any insulation on the basement walls, the drywall or the framing used to finish the basement.
