On August 7, 2008, Zhu Dongqing, Chairman of China Construction Waterproof Materials Industry Association, participated in the waterproof technology exchange activities of the Second Nuclear Institute. The conference focused on the technical and regulatory issues of single-decked roofs. Zhu Dongqing, chairman of the board of directors, disclosed that in order to adapt to technological development and promote industrial progress, the "Technical Code for Slope Roofing Projects" is being developed to make major adjustments to the waterproofing level. The level is reduced to two levels, which will be an important breakthrough.
In the original waterproof and defense level system, one or two grades cannot be waterproofed with a single layer of material, and there must be new specifications to undertake the progress of waterproof technology. Zhu Dongqing explained that the purpose of grading the waterproof and security system is to divide the waterproofing into 25 years, 15 years, 10 years, and 5 years according to the age of use. However, the original detection method cannot identify the useful life of the material, so multi-channel protection is used. The theory replaces the service life, divides the number of roads for fortification and the grade of waterproof fortification on the materials, which has played a certain role in promoting the development of the industry. However, with the continuous improvement of EPDM, pvc, TPO and other polymer materials in materials and construction technology, single-layer roofing technology has gradually matured and is used in large quantities in developed countries. It is reported that more than 60% of commercial roofs in the United States are Use a single-layer waterproof approach. In response to the requirements of national building energy conservation and environmental protection and to keep up with the pace of material upgrades, China Construction Waterproofing Material Industry Association established the China Construction Waterproofing Association Single Roof Technical Committee in August 2007 to promote the progress of China's single-layer industry. To regulate the development of a single-story roofing market, simplifying the original grading is also a requirement for technological progress and industry development.
At the meeting, the company Firestone Building Products Europe introduced the application of EPDM waterproofing membranes in a single-layer roofing system.
Background information: The original waterproof and waterproof system divides the waterproof level into four levels. The first level requires three or more waterproof defenses, the second level requires two waterproof defenses, and the third and fourth levels require one waterproof fortification. The specifications are also applicable to the The type, thickness, etc. of the material are all required, so one or two grades cannot be waterproofed with a single layer of material, the level of the three or four levels of waterproof is low, and one or two layers of waterproof are required.
