Currently, in our country, industrial, civil, military, water conservancy, and civil foundation projects experience varying degrees of leakage and cracking either before they are fully constructed or within two to three years after completion. "What should not leak does not, but what should not, leaks everywhere." There is a famous saying: "Three parts material, seven parts construction," which highlights the importance of waterproofing construction standards and techniques. Technology is the most critical aspect of the entire building waterproofing project. The social responsibility of practitioners also relates to the success or failure of building waterproofing. In our country, the annual drainage from tunnel constructions causes incalculable losses to the ecology and the nation. Most of the tunnel seepage is primarily managed through diversion and discharge, with prevention as a secondary measure. The amount of electricity used for pumping water annually and the consequences of mountain desiccation are astonishing. After many years in the industry, I believe that water can be completely blocked within rock and mountains, but there is still a long way to go to achieve this. Chongqing 18 Tu Xin Cheng Grouting Waterproof Engineering Co., Ltd. was founded in 1999 and later re-established in Zhongxian, Chongqing, in 2006. The company integrates scientific research, production, construction reinforcement, and material sales, mainly producing high-end waterproof materials, self-adhesive membranes, immediate water stoppers, cement-based penetrating crystals, and various grouting and plugging materials. Developing new materials, promoting new technologies, and achieving less seepage and less drainage in our tunnels as soon as possible, along with waterproofing and plugging materials, and construction techniques, is the sacred responsibility of our generation of waterproofing professionals. We aim to bring our environmentally friendly, high-performance, and easy-to-apply new generation of waterproof grouting and reinforcement products to the market, offering extensive quality assurance, enthusiastic, and considerate service, and working hand in hand with you to create a better future!
