Basement waterproofing is an important link in building engineering, which is not only related to the service life of buildings, but also related to people's quality of life. This paper will introduce three common basement waterproofing methods to help you choose the appropriate waterproofing scheme.

External defense and external sticking method

External defense and external sticking method is to lay a coiled material waterproof layer on the bottom cushion, and then directly lay a vertical coiled material on the outside of the retaining wall. This method can effectively prevent indoor humidity, especially suitable for large excavation and sheet pile support foundation pit.

Anti-sticking method

Anti-sticking method is to build a permanent protective wall first, and then spread a waterproof layer on the protective wall and the bottom mat. This method is an ideal choice when the construction environment is limited.

Exterior wall lining waterproof

The waterproofing of off-wall lining is to add an off-wall inner wall outside the concrete wall and the inner surface of the retaining structure. Although the cost is high, the drainage effect is good, and the water tightness of the concrete joint of the column wall is more guaranteed.
