Proposed procedures are verified by both the numerical and physical experiments. Reaching the volume stability results in the significant reduction of crack evolution. The compact concrete therefore provides protection for reinforcement, and so these structures can also be used in an aggressive environment. The goal of this work is to propose a methodological approach ensuring the highest possible reduction of crack evolution and yielding watertight concretes. The main causes of crack evolution in an early stage of concrete are the hydratation heat and shrinkage. To reach the water tightness and the volume stability of concrete, suitable casting procedures such as casting in layers and an application of HKrystal in dilatation joints are proposed, which allows us to control the evolution of hydratation heat.
