One of the primary sources of water leaks in modern concrete block walls is cracking in the head joints. This behavior is often visible as a small separation or bond failure between the mortar and the block unit. This type of cracking is distinct from assembly shrinkage cracking because the separations are generally confined to the mortar joints and do not extend vertically through block units. The cause of this type of behavior is plastic drying shrinkage of mortar (i.e. shrinkage of the mortar while it is still uncured).

The University of Wyoming and Atkinson-Noland & Associates recently teamed up to examine potential causes and aggravating factors for this cracking. This presentation will discuss the findings of this research and seek input on your experiences.
