The invention discloses a formula of water-proof dry-mixed mortar. Materials in the formula comprise aggregates and additives, wherein the aggregates comprise cement, water and sand; the additives comprise a water reducing agent, an expanding agent, a water repellent, latex powder and a cellulose ether; the mixing ratios of the aggregates in the water-proof mortar are as follows: the water-cement ratio is 0.487:1, and the cement-sand ratio is 1:2.5; the mixing amounts of the additives relative to the cement are respectively 0.825% of the water reducing agent, 8% of the expanding agent, 0.25% of the water repellent, 0.44% of the latex powder and 0.6% of the cellulose ether. The formula is clear and simple, the mixing of the dry-mixed mortar is extremely convenient, and the water-proof and seepage-proof properties of the product are great.
