Spall Repair of Horizontal Concrete Surfaces

Horizontal surface repair is common on slabs either elevated or on grade. Deterioration may be caused by corrosion of embedded reinforcement resulting in delamination and spalling. Other common causes include freezing-and-thawing

deterioration and chemical attack. After an evaluation of the deterioration by an engineer, a plan should be developed including objectives and specifications for the repair. Steps for repairs that include layout, removals, edge preparation,

mixing, bonding, placement, and curing have been included below as a step-by-step guide for use by field personnel.
