The present invention relates to a waterproof mortar composition. The composition has excellent adhesiveness to the existing concrete material, maintains appropriate workability, can provide desired strength in a short time, and thus is proper to be used to repair an old road or a damaged portion of a road. The composition is effective for blocking water from a building complex including roads. The composition includes 15-40 wt% of pretreated silica, 25-45 wt% of an inorganic binder, 15-25 wt% of silica, 5-10 wt% of phosphate, 2-10 wt% of aluminum oxide, and 2-10 wt% of magnesium oxide. The composition can prevent cracks and swollen portions of a construction area, has increased adhesiveness to an object, and can increase waterproof efficiency resulted from tight sealing of a silane-based resin. |
