3 Rebar Mistakes That Crack Buildings

The damage starts long before the cracks. Hidden rebar errors in cover, lap length, and spacing can quietly weaken the whole structure.

This is how buildings fail — and it’s hidden inside the concrete. #1 No concrete cover. Steel exposed to air or soil rusts fast, so keep proper cover. #2 Short lap splice. If bars are too short, load transfer breaks. Use the correct lap length for tension and compression. #3 Wrong spacing. Too wide reduces strength. Too tight blocks concrete flow. Keep spacing within code and aggregate limits. You won’t see these mistakes until cracks start showing. Concrete hides it… but rebar decides everything. Follow for real construction truths.
