Shenzhen zhongshenglong waterproof decoration Co., Ltd, Grouting is the use of mechanical high-pressure power, water-soluble polyurethane chemical grouting material into the concrete cracks, when the slurry meets the water in the concrete cracks, it will quickly disperse, emulsify, expand and consolidate, so that the consolidated elastomer fills all the cracks in the concrete, and completely blocks the water outside the concrete structure, so as to achieve the purpose of water stop and leakage stoppage. Component grouting and plugging technology is a new advanced technology of high-pressure airless grouting, which is a new technology used in water-soluble grouting materials in developed countries.
