In the case of water treatment facilities,concrete structures are mostly made of concrete structures,and corrosion is caused by various deterioration factors in the use of concrete materials.Accordingly,the waterproofing and durability of water treatment facilities are used to prevent moisture and durability.Various materials and methods are developed for waterproofing and waterproof materials,but there is still a problem in many areas where continuous defects are encountered in many areas where water treatment facilities are degraded or contaminated with water treatment facilities.To ensure long-term durability of the water treatment facilities,the company developed a comprehensive composite waterproofing and reinforced concrete repair system with a cross section of concrete,and developed a dual composite waterproof system using a cross section repair system and a cross section of a wet surface.
