The permeability level and resistance of the concrete cutoff wall of earth dam on the penetration of fluids are crucial factors and have an essential effect on the stability of the concrete core. In this research, the simultaneous incorporation of nano-carbon black and nano-silica in the concrete with nine different mixing patterns is considered to investigate the permeability and mechanical properties of the concrete. Experimental results revealed that the addition of nanoparticles to the concrete considerably decreases permeability; while reducing the compressive strength in some mixtures and increasing the bending strength of the modified concrete in most of the studied cases.
