The purpose of this study is to estimate the permeability coefficient of concrete using mass hydrophobation agent. Experiments were carried out by making concrete specimens with different amounts of mass hydrophobation agent. It is considered that the pores are filled in the internal structure of the concrete by the expansion of the mass hydrophobation agent.
