1、基坑周围的地面水应加以排除或控制，使其不流入基坑，同时要准备好排水措施，以防基坑中雨水积聚。用冷粘法施工的卷材防水层，施工完毕后还需留下排水装置，继续排水7d以上，以保证胶粘剂的充分固化，避免因过早撤掉排水装置而导致地下水上升到防水层、水压顶开卷材搭接部位的胶粘剂和密封膏，造成渗漏或鼓泡现象。
Surface water around the pit should be excluded or control, it does not flow into the pit, and to be ready to drainage measures to prevent the accumulation of rainwater pit. Cold bonding method of construction waterproofing membrane, the need to leave after the completion of construction of drainage devices continue to drain 7d above, in order to ensure adequate curing adhesives to avoid prematurely removed the drain which led up to the waterproof layer of groundwater, water pressure lap top open coil parts adhesives and sealant, resulting in leakage or bubbling phenomenon.
2、 金属层防水。这是在防水建筑的内部，焊贴一层金属板以达到抗渗防漏目的的一种方法。这种方法适用于防水要求较高的工程。
This is inside the waterproof construction, welding a metal plate affixed to achieve a lof method impermeability purposes. This method is suitable for high water requirements engineering.
3、刚性抹面防水。这是采用防水水泥砂浆或掺外加剂的防水水泥砂浆对建筑物进行抹面而达到抗渗目的的一种方法。
It is waterproof cement mortar or cement mortar mixed with additives waterproof plaster of buildings to achieve a method of impermeability purposes.
4、地下工程的卷材防水层应选用高聚物改性沥青类或合成高分子类防水卷材。
Underground engineering waterproofing membrane should use polymer modified asphalt or synthetic polyed waterproofing membrane.
5、涂膜防水。此法价格低廉、施工方便。
This method is inexpensive and easy construction.
6、防水混凝土结构防水。这是采用提高混凝土密实性的办法，提高结构混凝土的抗渗性，还可满足一定的耐冻融和耐侵蚀的要求。
This is the use of concrete to improve compactness approaches to improve the impermeability of the concrete structure, but also to meet certain requirements for resistance to freezing and thawing and erosion resistance.
7、排水减压法。排水减压法是在建筑物底下做出盲沟，创造自流排水的条件，当无自流条件时，可通过盲沟将水引入集水井中，再用水泵抽排引走，减少水对地下工程的渗压，起到防水作用。
Decompression method is to make a blind drainage ditch beneath the building, creating gravity drainage conditions, when there is no gravity conditions, can be introduced by the blind ditch water collection wells, then pump pumping lead away, reducing water underground engineering the osmotic pressure, played the role of water.
