Polyurea spraying apparatus waterproofing method and waterproofing structure using the same

摘要

The present invention relates to a polyurea sprayer and a waterproof construction method and a waterproof structure using the same. The waterproof structure using the polyurea sprayer includes: a waterproof layer made of at least one waterproof materials on a concrete floor surface; and a junction layer formed by connecting the waterproof materials with each other by spraying polyurea to the waterproof layer through the polyurea sprayer including a storage part having a temperature maintenance function and a circulation part circulating a main agent and a curing agent. According to the present invention, since polyurea is continuously and uniformly supplied through the polyurea sprayer including the storage part maintaining the main agent and the curing agent at a proper temperature and a circulation part circulating the main agent and the curing agent to prevent the agents from being solidified, the present invention is capable of reducing time and costs for construction as well as waterproofing a painted surface of a complex structure such as a slope or the like.
