What is Joint Spalling Repair in Concrete Pavement about?

Joint spalling in concrete warehouse floors is caused by hard wheels on lift trucks impacting the joint edges. To repair spalling under 1 inch wide, the joint should be routed out and refilled with a semi-rigid filler. For spalling over 1 inch wide, the distressed concrete must be removed and the joint repaired with mortar before refilling. For long term performance, joints must be refilled full depth with flexible fillers that provide support but allow for concrete movement.
