What kinds of basement waterproofing practices

Basement waterproofing practices can be divided into the following, each method has its own specific application scenarios and advantages:

1, structural waterproofing:

Principle: the use of waterproofing concrete impermeability and densification of waterproofing.

Application scenarios: suitable for basements, underground pump rooms, pools, underground passages and so on.

Advantages: directly through the characteristics of the concrete structure to achieve waterproofing effect, construction is simple.

2, plus waterproofing layer:

Principle: waterproofing layer on the outside of the structure to increase waterproofing.

Waterproof layer materials: commonly used cement mortar, coil (such as SBS modified bitumen waterproofing roll-roofing), waterproofing coatings (such as polyurethane waterproofing coatings).

Application scenarios: according to the waterproofing needs and construction conditions to choose the appropriate waterproofing layer materials.

Advantages: waterproof layer materials are diverse, you can choose the most suitable waterproofing materials according to the specific conditions.

3, seepage and drainage waterproofing:

Principle: the use of blind ditch, seepage and drainage layer and other measures to exclude the nearby water source, in order to achieve the purpose of waterproofing.

Application scenarios: for high water table or the need for long-term drainage of the basement.

Advantages: through drainage measures to reduce the impact of groundwater on the basement, improve the waterproofing effect.

4, combination of internal and external waterproofing:

Principle: combination of external waterproofing and internal waterproofing practices to achieve better waterproofing effect.

Construction method: external waterproofing in the foundation after the bedding, basement floor before rebar binding construction; waterproofing in the basement after pouring on the inside of the wall with waterproofing materials for construction.

Advantages: a combination of external waterproofing and internal waterproofing advantages, improve the reliability and durability of the waterproof layer.

5, elastic material waterproofing:

Principle: the use of elastic waterproofing materials (such as EPDM rubber roll-roofing, polyurethane coated waterproofing materials) for waterproofing.

Application scenarios: for the higher requirements of waterproofing performance of the basement.

Advantages: elastic waterproofing materials have good flexibility and durability, can adapt to the basement structure of the small deformation.

In the choice of basement waterproofing practices, need to base on the specific conditions of the basement (such as geological conditions, water table, use requirements, etc.) for comprehensive consideration, and choose the most suitable waterproofing practices. At the same time, in the construction process, need to pay attention to construction quality and detailing to ensure the reliability and durability of the waterproof layer.
