Background

The phenomenon of water leakage of roof top plates or roof bottom plates caused by cross layers is difficult to thoroughly solve by using a common waterproof mode. The construction process through grouting can be very simply and effectively solved, but the construction cost is greatly increased due to the fact that the trend and the coverage degree of slurry cannot be seen in the construction process, and the building can be damaged to different degrees due to long-time high-pressure grouting.
