Beijing Heng Jian Bo Beijing Waterproof Materials Co., Ltd. (www.hjbjfs.com/) located in Beijing Tongzhou District of Beijing Song Town, Tongzhou District High Xinzhuang Industrial Park, Contact: butter head position Manager Note 1, butter head eraser Since the gasket in the construction process, the pressure is too high and corrosive chemical grouting materials, easily damaged. So in the construction process, damage is found, should be replaced grouting machine, or cause leakage of plasma. 2, at the end of construction, due to the washing machine with a cleaning agent, butter head eraser have a corrosive effect, resulting in butter head eraser easily damaged, so the next time the construction, should be replaced. Grouting plugging basement construction site concrete construction program hornet not dense parts of plugging construction, MA cellular concrete chisel out using surface not dense parts, quick-setting sealing material reinforced after the closure level, and then drilling grouting plugging. 2, after the high-pressure grouting, if found surrounding still leaks, should be broadened to take the same approach, grouting plugging leaks. 3, in the construction process, the horse honeycomb concrete surface cracks holes, sealing treatment should focus on accelerating plugging plugging material reinforced flat seal to prevent leakage of the sealing agent waterproof grouting machine, affecting the quality of results. 4, after the first pass pressure grouting grouting machine manufacturers, stay an hour later, the same at all points of leakage sealing agent again repeat inject cement grouting, grouting in order to achieve concrete results and full expansion slot density. 5, grouting pressure should observe strict control pressure gauge and years of combined experience handling construction plugging leaks and leaks of various circumstances, take a variety of construction methods grouting plugging construction deal.
