The problem of basement leakage stoppage has always been a big problem in China

The basement leakage stoppage problem has always been a big problem in China. Of course, the state has formulated the basement waterproof specification, which requires that the underground engineering must be waterproof design. So what kind of basement waterproof measures can be divided into? Yancheng Huazhong waterproof plugging said that the basement waterproofing measures currently used are coil waterproofing and concrete self waterproofing.

1. Concrete self waterproofing

(1) self waterproofing of shrinkage compensating concrete structure

(2) synthetic polymer waterproofing membrane, polymer modified asphalt waterproofing membrane or synthetic polymer waterproof coating (only applicable to external anti sticking method)

(3) the combination of rigid waterproofing and flexible waterproofing should be adopted in basement waterproofing. The thickness and strength grade of structural concrete self waterproofing shall be selected by structural design, and its impermeability grade shall not be less than P8. Micro expansion agent, compactor and water reducing agent should be added into concrete.
2. Waterproofing of coiled materials
The membrane waterproof layer is directly pasted on the external surface of the main body. The waterproof layer is synchronous with the concrete structure, less affected by the settlement and deformation of the structure. It is not easy to damage the waterproof layer during construction. It is also convenient to check the waterproof quality of the concrete structure and the coiled material, and it is easy to repair the problems found. The disadvantages are that the waterproof layer needs several times of construction, many processes, long construction period, large working face, large earthwork volume, large amount of formwork, difficult protection of coil joint, and easy to affect the quality of waterproof engineering. Using these two waterproof methods can effectively solve the problem of basement leakage
