地下室、半地下室及机械设备坑等使用后出现渗漏水现象很普遍。有的工程虽在施工时做了防水处理,但有的因施工质量不好导致渗漏;有的因防水材料的质量问题(如材料老化)而发生渗漏。针对这些情况,我们在工程实践中采用水玻璃及防水粉两种材料,利用它们各自的特有功能,在防水工程中取 Water seepage after basement, semi-basement, mechanical pits, etc. is common. Some projects have been treated with waterproofing during construction, but some have caused leakage due to poor construction quality; some have leaked due to quality problems of the waterproof material (such as material aging). In view of these circumstances, we use water glass and waterproof powder in our engineering practice. We use their unique features to take in waterproof projects.
