How to avoid greater loss in the construction of basement leakage stoppage

News Abstract: usually in the basement leakage, will according to the situation of leakage to the owners of small economic losses, and often in the basement leak stoppage construction, due to the construction party's unprofessional plugging method, but will bring more losses to the owner, so in the case of basement leakage, we must be calm, not because of the price of the construction party It is cheap and neglects the construction quality.

Usually in the basement leakage, according to the situation of leakage, it will bring small economic loss to the owner, and often in the basement leak stoppage construction, because the construction party's unprofessional leak stoppage method, on the contrary, it will bring more losses to the owner. Therefore, when encountering the basement leakage, we must be calm, not because the construction party's price is cheap The construction quality is ignored.
First of all, we should understand why there is leakage in the basement. Because the underground is relatively humid, it leads to the loosening of concrete, resulting in cracks and pores, which leads to leakage. The correct choice of construction technology can quickly solve the problem of leakage, but also can ensure the quality of engineering construction and avoid leakage again.
Before construction, it is necessary to find out the leakage point, clean up the surface of the leakage point, and chisel the groove with steel drill. The groove width is 60-100 mm, and the groove depth is 70-100 mm. It is concave (large inside and small outside), and the specific situation depends on the site.
According to the concrete requirements, put the rubber strip into the slot to seal the leakage, and then put it into the cement slot according to the concrete requirements.
Back pressure grouting: the pressure of grouting must be greater than the pressure of water leakage, so as to push the water back and infiltrate into the coarse and fine joints of the concrete. The molecular weight of grouting material is less than 107-108, and it is directly injected into the pores and leakage joints of the concrete to expand and quickly set when meeting water, so as to achieve the effect of long-term deep water stop.
