The automatic low-pressure grouting technology is a comprehensive technology for the concrete crack grouting field developed by the crack treatment center of Beijing Metallurgical Engineering, including materials, machinery and construction. After the grouting is repaired, the inside of the crack is filled with AB-1 grouting resin, and its tensile strength and bonding strength are high, and no cracking occurs again.
2. Cracks in brick masonry walls, cracks in new partition walls and cracks in walls of different materials are all temperature seams, which cannot be grouted and repaired. Because of the expansion and contraction of cracks, flexible materials should be used for repair (such as Beijing Metallurgical Construction).
