On September 23, 2022, the online review meeting for the China Engineering Construction Standardization Association (CECSA) standard Non-Water Reactive Two-Component Polyurethane Grouting Material (Draft for Approval) (hereinafter referred to as the Standard (Draft for Approval)), co-edited by the Chinese National Committee on Large Dams and Beijing Reinno-Tech New Energy Technology Co., Ltd., was successfully held. The meeting was chaired by Mr. Wang Hailong, Deputy Secretary-General of the Waterproofing, Protection, and Rehabilitation Professional Committee of CECSA.

The review panel consisted of seven experts, including Senior Engineer Cao Zhengfu from the Architectural Waterproofing Academic Committee of the Architectural Society of China and representatives from China Building Materials Academy Suzhou Waterproof Research Institute Co., Ltd. They conducted a comprehensive review of the Standard (Draft for Approval).

After evaluation, the experts unanimously agreed that the Standard (Draft for Approval) features advanced, reasonable, and complete technical content with strong practicality. It fills a gap in domestic and international standards for this product and will serve as a guiding document for the industry upon its compilation, release, and implementation, reaching international standards. The panel approved the Standard (Draft for Approval) after review.

The Standard (Draft for Approval) provides a standardized basis for the application of non-water reactive two-component polyurethane grouting materials in various construction projects. It holds significant practical value and guiding significance in addressing complex engineering challenges and lays a foundation for the further development of this technology. The drafting team will now refine the content based on expert feedback before proceeding to the final approval stage.
