Reasonable crack widths for reinforced concrete under service loads are listed in Table 4.1 of ACI 224R-01. However, a footnote warns that, with time, “a significant portion” of the cracks in a …
How to Determine the Severity of Concrete Cracks?
The maximum allowable crack width on the foundation is nearly 3.2 mm. Damping and watertight agents can bridge a crack width of 3.2 mm. It would be best to repair cracks that are located in high-visibility areas of a concrete structure.
