From the second hole 20-1, the hole forming step S100 for forming a portion of the hole to cross each other, and the waterproof material 30 mixed with a curing agent in the hole 20 formed in the hole forming step Injecting, but the waterproof material injection step (S200) of injecting the waterproofing material in any one of the manual or injection-type injection method using the injection device, and the waterproofing material leaks through the inlet of the hole 20 after the waterproofing material injection. In order to blockade is made of a blockade step (S300) for closing the hole inlet using a stopper (40).
