Shenzhen city's zhuobao technology group (hereinafter referred to as “choubao technology”) was established in 1999 as a service provider for water protection systems, mainly for the production of functional construction materials, water protection works and decorative heating projects. The zhuobao technology headquarters is located in shenzhen and is located throughout the country. It has seven production bases in tianjin, huizhou, wuhan, hubei, suzhou, chengdu and fushan, and has established more than 30 branches in provincial capitals and cities. The products cover four main types of waterproof buildings, domestic waterproofing, decorative temperature protection, rainbow pumping and drainage, and hundreds of varieties. Chevalier technology was created in the industry. As the representative brand of china's own adhesive water-proofing scrolls, zhuobao has introduced and implemented the concept of “skin-like” water-proofing, and has independently invented construction methods such as wet-painting, pre-painting and anti-mixing, so that the construction of water-protected scrolls is written in the relevant norms. In order to solve the problem of water protection, zhuo po developed an integrated system for external water protection, which brings together three main products, five major patents, with the advantages of `one process, two functions and three defences'. In 2014, the zero deficiencies water services system was launched, which integrates all aspects of water protection works and combines financial and financial efforts to build an insurance system for water protection works, with due regard to ensuring “double compensation in case of leakage”. In keeping with the standard of “doing a project, a monument of trees”, the zhuobao technology has extensively applied to major infrastructure construction, industrial and civil construction, commercial construction, etc., and has forged many classic projects such as the building of the ministry of public security and the shenzhen base in hua, which have won the luban prize. Zhubo technology is well developed. There are currently four industry standardization laboratories, and the r & d technology centres integrate the company's comparative technological resources, focusing on research and development, technological improvements and quality upgrading in technologies such as revised asphalt, waterproof paints, high molecular rolls and waterproofing systems. Chew po focused on the development of waterproof talent. The zhaobao business school was established in july 2013 as an early business school in the chinese construction industry. As the main training base for the construction and water prevention industry in china, a large number of technical and managerial skills have been developed for the industry。
