This chapter focuses on the causes and the mechanisms of debonding of cement-based material overlays. Additionally, it describes how debonding affects durability of the composite structure. Methods for monitoring are described. The debonding mechanism is discussed, and debonding modeling is described. The role of reinforcement in debonding is important and is discussed. Crack propagation and crack opening affects debonding and is described. There are special overlays including those bonded to steel and overlays that are anchored to the substrate with metal anchors and they are discussed. The effect of boundaries and joints is discussed.
