Basement cushion waterproof
Second, when the design of the highest groundwater level above the bottom of the basement floor, you must do waterproofing. As the waterproof waterproof effect is good, so the application of more. Internal waterproofing is generally used for repair works.
Five, how the basement moisture:
1, moisture-proof material
This is the decoration in the attention of the problem, the basement is relatively humid place, so when we should pay attention to the decoration, the choice of wallpaper, tiles and other moisture-proof effect of better decoration materials, and other basement ceiling, floor, walls are To be the best waterproof.
2, ventilation and moisture
Strengthen the air circulation on the moisture is more helpful, can effectively reduce the indoor moisture content.
3, electrical dehumidification
If you run into the rainy weather, outdoor air humidity is relatively high, it is not suitable for long ventilation, you can use the exhaust fan, air conditioning or dehumidifier and other machines for indoor dehumidification.
4, desiccant dehumidification
In addition to the use of a variety of electrical dehumidification can also be placed some moisture damp dehumidification effect of small items, such as desiccant, charcoal and other indoor moisture, but the desiccant is a service life, the general need for frequent replacement.
5, to warm moisture
Installation of warmth is also one of the effective means of underground moisture protection, to warm the basement room temperature can be maintained at a certain temperature can keep the room dry and not wet, but pay attention to the temperature is not too high will cause the room is too dry, Comfortable.
Fourth, improve the waterproof performance:
1, Aggregate graded concrete, is the use of different aggregates of the aggregate and improve the content of cement mortar in the concrete, so that the mortar is filled between the aggregate, thus blocking the aggregate is not dense between the seepage channel , Improve water resistance;
2, plus concrete, is added in the concrete air conditioner or dense agent to improve the impermeability.
Third, the membrane waterproof in the construction should first do the basement floor of the waterproof, and then the membrane along the basement floor continuous paste to the outer surface of the wall. Basement floor waterproofing first in the foundation pouring C10 concrete cushion, the thickness of about 100mm. And then paste the membrane, and then in the coil to wear 20 thick 1: 3 cement mortar, and finally pouring reinforced concrete floor. The outer surface of the wall first wip 20mm thick 1: 3 cement mortar, cold base oil, and then paste the membrane, the membrane should be stitched paste, adjacent coil lap width of not less than 100mm. The top of the coil should be higher than the maximum water level of about 500mm, the outer side of the brick wall.
First, the basement moisture treatment structure is usually: first in the basement wall outer surface wiping 20mm thick 1: 2 waterproof mortar, basement walls should be used cement mortar masonry, gray seam must be full; and in the basement floor and the first Floor floor is divided into two walls of the level of moisture-proof layer. The outer wall of the basement wall should be tampered with the soil with poor permeability.
