How to fill the basement with water?

Suitable for large-area water leakage treatment of structures. Under normal circumstances, the treatment of basement leakage can not be carried out in front of the water surface, but only on the back. Therefore, drainage should be carried out before construction to prevent the newly made waterproof surface from being washed away by pressurized water.

The specific method of surface layer method: select the part where the water leakage is concentrated, open a hole and bury the pipe to make the water flow out of the conduit. According to the amount of water leakage, pipes can be buried at one or more places to divert water. When the water leakage point can't be found, the pipe can be buried at the lower part of the wall to divert water.

Then, according to the use requirements of the material, polymer cement waterproof mortar is applied to the waterproof part in a large area, and plastering is needed in layers, and the order is waterproof plain slurry-waterproof mortar-waterproof plain slurry, and finally the pipe is pulled to block water. For slight water seepage of concrete, apply inorganic quick-setting water-stopping material on the surface of concrete and rub it repeatedly with rubber gloves until Shui Ying can't be seen.

For holes and cracks with obvious basement leakage, the water stop treatment should be carried out one by one according to the treatment method of holes and cracks leakage. For the surface of the basement concrete structure, when there is less serious slow water leakage (such as sweating, wetting, etc.). ), you can brush polymer cement slurry on the back to form an impermeable covering layer on the surface, which plays an anti-seepage role.

The specific method is: the surface of the base is treated to be smooth, and the uneven parts are filled with cement mortar, compacted and polished, and the dust and oil stains on the surface of the base are removed at the same time, so as to facilitate the firm bonding of the waterproof layer.

(2) High pressure grouting method

In case of basement leakage, grouting method can also be used. According to the leakage situation, grouting holes can be set on the structure, and then grouting treatment can be carried out to form a waterproof curtain inside the structure. In addition, the method of "surface closed grouting" can be adopted, that is, first laying pipelines to pump water, and then plastering a large area with polymer cement waterproof mortar. After the mortar strength meets the requirements, water is blocked by grouting from the diversion pipe.
