DetailsHydraulic cement is best when used for minor patches or in moisture-heavy areas. Unfortunately, due to the rigidity of the structure after drying, hydraulic cement isn't a permanent fix for concrete cracks. The expansion and contraction of the surrounding concrete can cause the cracks to grow. Additionally, a hydraulic cement patch doesn't ...
