<p>The present invention relates to a 3-layered wall waterproof construction method wherein a waterproof layer is formed to enclose an outer portion of a wall to basically block off a penetration of an underground water into a cracked portion of the wall, and improve the durability thereof. The method includes the steps of: (ST 1) drilling holes in a cracked wall by a drill; (ST 2) inserting an injection pipe to inject a liquid into the drilled portions; (ST 3) injecting a first waterproof agent mixed with 80-90 wt% of 2-hydroxyethyl methacrylate and 10-20 wt% of water through the injection pipe; (ST 4) injecting a second waterproof agent mixed with 90-95 wt% of 2-dimethylaminoethyl methacrylate and 5-10 wt% of water through the injection pipe after the first waterproof agent is injected; and (ST 5) injecting a third waterproof agent containing disodium-peroxodisulphate through the injection pipe after the second waterproof agent is injected.</p> |
