济南专业防水/谈到将卷材防水层粘贴在地下工程结构的迎水面通常称外防水，贴于背水面称内防水。卷材外防水可以保护地下工程主体结构免受地下水有害作用的影响；防水层可以借助土压力压紧，并可和承重结构一起抵抗有压地下水的渗透。
Jinan professional waterproofing waterproofing membrane comes to be attached to the positive side of underground engineering structures usually called outer waterproof, affixed to the back surface of the water, said water-resistant. Waterproof outer membrane of the main structure can be protected from the effects of underground harmful effects of groundwater; waterproof layer can make use of compacted earth pressure, and the load-bearing structure together and resist pressurized groundwater infiltration.
济南专业防水/介绍内防水做法不能保护主体结构，且必须另设一套内衬结构压紧防水层，以抵抗有压地下水的渗透，有时甚至需设置锚栓将防水层及支承结构连成整体。因此，一般掘开施工的地下工程都不采用内防水做法，只是暗挖施工的地下工程，必须采用卷材防水而又无法采用外防水做法时，才采用内防水做法。
Jinan professional waterproof waterproof introduce the practice has failed to protect the main structure, and must be a separate structure lined with waterproof layer pressed to resist pressurized groundwater infiltration, and sometimes need to set anchor waterproof layer and the support structure integrally connected. Therefore, the general construction of dug underground engineering practices are not using waterproof, but the construction of underground tunneling project, waterproof membrane must be used with external waterproof but can not practice, practice before using waterproof.
