PURPOSE: A waterproof, explosion-proof, earthquake-proof construction method is provided to protect a structure from external impacts by improving crack resistance and impact resistance and reinforce service life of the structure. CONSTITUTION: A waterproof, explosion-proof, earthquake-proof construction method comprises followings. A surface of an object to be coated is cleaned by spraying high pressure air(S1). The percentage of water content is measured and a water leakage detector is installed(S2). Primer is spread on the surface of the object to be coated using a spray method or a brush, and a roller. A defect site is reinforced and conserved(S4). A primer surface preparation non-woven fabric is impregnated(S5). Two-component polyurea is sprayed at thickness 0.8mm and a pinhole is inspected(S6). The two-component polyurea is sprayed at thickness 0.8mm, and silica is sprinkled(S7). The thickness of the two-component polyurea film is measured(S8).
