Corrosion of Embedded Rebars in a Concrete Slab, Animal Feed Plant in Nacogdoches, Texas

A 55 year old severely corroded slab was being considered for demolition. C3S was retained to evaluate the slab and make a recommendation to client. Inspection of the slab showed the corrosion to be localized. Field and laboratory tests performed on concrete samples indicated the slab could be repaired. A competent repair contractor was contracted to repair the slab under supervision of C3S. The slab was restored at a reasonable cost and without interruption to plant operation.
