Since April, the North China Standard BJZ series special atlas "Underground Building Waterproof Structure- -SJ Series", edited by Hongdu Planning and Architectural Design and Research Institute Co., Ltd TD and co-edited by Suzhou Guardex New Material Technology Co., LTD., was officially printed and implemented. The atlas number: 22BJZ243.

North China standard BJZ series special atlas "underground building waterproof structure good-SJ series" mainly introduces the good SJ series waterproof materials used for underground engineering, municipal public engineering waterproof engineering structure and application technology, suitable for new, change (expand) in north China underground construction engineering and pool waterproof engineering design.

Atlas of underground building floor, side wall, roof waterproof structure, pool waterproof engineering practice, construction joints, deformation joints, after pouring belt waterproof structure, pile head, pull bolt waterproof structure, pipe wall, template bolts, urban comprehensive pipe gallery waterproof structure, dig station waterproof structure, mining tunnel, bridge deck waterproof structure have detailed construction analysis diagram, through the application of SJ series waterproof material, to meet the design requirements.

The atlas also expounds the product functions and performance indicators of Guardex SJ series waterproof materials, and describes the key construction points of SJ series waterproof materials, such as operation methods, material dosage, mix ratio, construction precautions, acceptance specifications, etc.

These are conducive to maximize the characteristics of SJ series waterproof materials in the architectural design and construction, to ensure that the waterproof engineering and the overall engineering quality meets the project design and actual application needs.

North China standard is Beijing, Tianjin, Hebei, Shanxi and Inner Mongolia five provinces (cities) general standard practice atlas, widely used in north China engineering construction, is the engineering construction standards, specifications, procedures, promote the transformation of scientific and technological achievements, promote important means and tools, to ensure and improve the quality of engineering construction in north China, improve the design efficiency, promote the construction industry technology progress has played an important role.

The implementation of north China Standard BJZ series special atlas "Underground Building Waterproof structure- -SJ series" has laid the technical foundation and standard basis for the promotion, design and application of SJ series waterproof materials.

Guardex SJ series waterproof materials include self-healing inorganic proliferation waterproof agent series and nano silicon ion immersion modifying agent series, which together form jiusi permeable crystalline structure self-waterproof technology system.

Guardex structure self-waterproof technology system not only activate the self-healing performance of concrete, dense concrete internal pores, cracks, and in the concrete surface 30~50mm construction and structure and the same life of waterproof layer, to concrete from the inside out, from the root to solve seepage, leakage, crack, prevention, protection, corrosion, repair, life 8 big waterproof problem.

Compared with the traditional waterproof method, the structure self-waterproof technology has the advantages of convenient construction operation, time saving, cost, safe, efficient and low carbon environmental protection, and the effect is deep into the concrete, and concrete integrated, a long life.

The self-waterproof technology system has been successfully applied in the main stadium of the Winter Olympic Games, the Nanjing Yangtze River Bridge, the middle route of the South-to-North Water Diversion Project, the Pearl River Delta water resources allocation project and other national key projects, And Xinjiang urban viaduct, Geku railway, Yantai port and other basic projects, Tianjin Beichen Sewage Treatment Plant, Guizhou Province Renhuai waste treatment pool and other industrial buildings, As well as Red Star Macalline, Shandong Jining shanty Renovation and People's Livelihood Project, Hangzhou Smart Valley Phase II, Nantong Rudong Dear Home Project, Xiqiao Liverpool University, Shandong Weifang Yunchuang Golden Valley project, Jinan Shanghe Industrial Park project, Shaanxi Xi' an Airport New City project and other civil buildings, Greatly improve the self-waterproof effect of the construction engineering structure, Provide waterproof protection for the project with the same life as the building.
