Researchers tried almost every feasible material to be mixed in concrete to vary some of its properties. To this end, the study proposes a model to predict changes in the amount of water runoff through cracks over time when spherical SAPs in superabsorbent material exhibit rapid swelling by absorbing the first water ingress after the occurrence of cracks. In this research superabsorbent polymer is going to be used as an admixture to improve its water tightness properties especially in aeration basins, concrete tank, and retaining structures. The concrete tries to seal the leak by blocking the water path by semi-solid gels. This gel is the product of the interaction of the superabsorbent polymer with water. Several samples were prepared to study the effect of the superabsorbent polymer on the concrete mechanical properties and on the concrete capability to block the water flow. In this study sodium polyacrylate were used as a super absorbent polymer (SAP). Concrete cubes, concrete beams, and concrete cylindrical samples were prepared to study the concrete strength of concrete mixed with superabsorbent polymer. Also concrete short cylindrical samples were prepared to study the concrete ability to block the water flow. These cylindrical samples are intentionally broken into two approximately equal pieces to create an induced crack. The artificially cracked samples were subjected to water pressure to study the concrete ability to stop the water flow though the induced concrete crack. Two kinds of water pressure are going to be consider in this research; the constant head and the falling head. And we were trying several proportion of superabsorbent polymer to find the optimum amount of doses require to seal the crack.
