目前国外建筑防水材料的生产设备比较先进,产品品种较多。而当前我国建筑防水工业与发达国家的差距较大,建筑物严重渗漏。现在出现的四漏问题(即屋面漏雨、厕所卫生间漏水、装配壁板渗水、地下室上水)已成灾,是建筑工程中防水质量低劣的通病。据有关部门调查、全国每年用于防水工程的维修费用约5亿多元。可见将防水材料更新换代、改进防
At present, the production equipment of foreign construction waterproof materials is relatively advanced and there are many varieties of products. At present, there is a big gap between China’s building waterproofing industry and developed countries, and buildings are seriously leaking. The four-leakage problem that has emerged (ie, roof leaks, leaking toilets, seepage of water in the siding, and watering in the basement) has become a common problem. It is a common problem in construction projects where the quality of waterproofing is poor. According to investigations by relevant departments, the annual maintenance cost for waterproofing projects in the country is about 500 million yuan.
