The project for a big new one locating at Guangzhou Provicne in south of China, near the river, the shallow underground water level, the foundation of saturated silt, unable to handle the precipitation, waterproof construction difficulty is great, high seal reliability is required, specific requirements: must be able to construct in water, shorter construct time , conveniently maintenance.
Given the senor building materials co., LTD., for the purposes of the other engineering provides 5 years within the redundancy of waterproof repair technology services and other projects of leakage repair services, reliability is the test of time and the owner's approval, therefore, after careful screening of party a, decided to adopt redundant reliability, sealing technology for the new project of waterproof construction.
In view that Sainuo redundant seal maintainenance technology has been adopted for 5 years which reliability has been verified by time and proprietor， finally, after carefully study and comparison, Sainuo redundant waterproof technology is approved to be constructed on the new large project.
