When cracks get wider than 1/16th of an inch, they are often being caused by the slab bending. There is no need to worry about shrinkage cracks. Such cracks are called shrinkage cracks and are usually less than 1/16th of an inch wide. The shrinking can cause cracks of various sizes. When concrete cures, that is as it hardens, it shrinks a small amount. Spalling that resulted from the hard-rubber-tired forklifts restocked empty shelves during the night shift.Every foundation has cracks in it!

The crack is routed with a diamond blade to create a groove, filled with epoxy until refusal, and then surface This sealant can handle cracks up to 3 inches wide. The solution is similar to that where water infiltrates through a slab crack. Budget-friendly Sashco’s Slab Concrete Crack Repair is all about flexibility, stretching up to three times the width of the cracks it repairs. While the theīalance of the crack depth may be hairline, at the surface of the slab a wide furrow results. Situation is common in storage facilities where, over time, the tires of fork lift traffic used to stock shelving accelerates the spalling and creates a tripping hazard. Infiltration finds an adjacent crack through which to infiltrate, in which case an extension of the original remedial effort solves the problem.Īnother crack problem, not necessarily associated with water infiltration, is the breaking away or spalling of small pieces of concrete along the two edges of the crack length. The epoxy fills the cracks and almost always completely curtails the leak. Our approach is to route the crack with a diamond blade to create a groove, fill the groove until refusal with an epoxy ofĪppropriate viscosity, and then grind smooth the surface to avoid tripping hazards. These leak occurrences are conceptually easy to curtail. As does leak remediation, concrete slab crack repairs also takes many forms, all of which we address.Ī common occurrence is water infiltration through cracks in below-grade concrete slabs, often due to tidal fluctuations and sometimes due to intense, long duration rain and sometimes a combination
