The invention relates to a waterproof additive for cement, wherein components comprise calcium lignin sulfonate, a FDN water reducer, stearic acid, fly ash, lime, calcium sulfate, aluminum sulfate, polyethylene amide, hydroxy carboxylate, and sodium fluorosilicate. According to the waterproof additive prepared by using the formula of the present invention, permeation resistance and leakage resistance are strong, such that the outer surface and the internal of the cement wall or ground becomes oil-based so as to significantly improve water resistance, permeation resistance and leakage resistance of the cement; and the waterproof additive has characteristics of low cost, convenient construction, aging resistance, and long service life, and can be widely used in roofs, kitchens, bathrooms, basements, outdoor walls, water reservoirs, tunnels, culverts, and other moisture-proof and waterproof projects of industrial and civil building.
