In this paper, issues limiting the durability of structures with reference to permeability to water, reinforcement corrosion, the occurrence of cracks, and degradation of cracks have been studied and addressed with possible solutions. The major issues identified are because of the water ingress, in particular capillary absorption and permeability, to address these problems and to identify possible solutions to the problem an experimental procedure is proposed to assess the different concentrations of concrete. The different concentrations of concrete include styrene butadiene rubber (SBR), acrylic polymer (AC), and Natural rubber latex (NR) and their combinations with each other. The experimental procedure includes the formation of 150 X 150 X 150 mm cubes of different concentrations of concrete which are normal or without chemical (WC), SBR, SBR+AC, AC, SBR+NR, and AC+NR. With these cubes of different concentrations, four experimental tests were conducted in the lab to assess the compressive strength and the reduction in permeability in comparison with the normal concrete, these tests are compressive strength, ultrasonic pulse velocity (UPV), rebound hammer test, and permeability test. In the test, the most effective solution is the addition of SBR, and by adding SBR (10% by the weight of cement) compressive strength was reduced by 5% and 60% reduction in permeability in comparison with the normal concrete.
