Many homeowners may be tempted to use caulk or hydraulic cement to patch basement wall cracks. It would be a little more expensive, but much better to have it sealed by a basement waterproofing professional. Caulk is superficial and will allow water to continue seeping behind the patch material, resulting in efflorescence, and eventually the caulk will peel off exposing an enlarged crack. Hydraulic cement does not bond well, also leading to efflorescence. Eventually, the water seepage will dislodge the cement plug. Also with these repairs water will remain on the backside of the crack and freezing in the winter will cause the foundation crack to expand even more.
A good qualified waterproofing and foundation repair specialist usually have nearly a 100 percent success rate for crack repair work. Most contractors offer lifetime warranties for the injection repairs because they are confident in the product quality and the training received from the chosen manufacturer, and most waterproofing contractors perform multiple concrete repairs per day.
Injection products create a win-win situation for the contractors, homeowners, and business owners. Contractors can reliably fix an inconvenience, while saving their residential and commercial consumers thousands of dollars for more extensive repair work and avoiding the inconvenience of excavation.
