Follow lap splice guidelines. Lap splices allow two lengths of reinforcement or two ends of welded wire reinforcement to be joined with the intent of acting as one continuous section of reinforcement. Minimum lap splice lengths are dictated by ACI 318 and depend on the concrete strength, steel grade, reinforcement bar size and spacing.
