The waterproof layer of the bathroom is full of small holes

Bathroom leakage is a common problem in building construction, and waterproofing should be done when decorating the bathroom. Next, Xiangxiang summarized the following waterproof technical measures according to the waterproof construction practice of technicians, and received good results in the construction of residential buildings.

A. The bathroom floor of the residential building is usually 2-3cm lower than the indoor ground, and the water supply and drainage pipes of the toilet pass through the bathroom floor.

B, the base waterproof technical measures in the construction of the toilet cast-in-place board, according to the design of the toilet wall position, on the board to make a return to 60mm high, width of 60mm concrete waterstop, and cast-in-place plate construction at the same time, and reserve a variety of pipe holes, to avoid digging holes in the floor in the future, leaving hidden dangers of water seepage; The concrete construction of the floor slab must be vibrated and compacted, especially around the pipe and the corner of the wall, it must be smooth to avoid unevenness, and the quality inspector must strictly control the quality, and the unqualified place must be reworked.

C. The technical measures of the ground cushion to prevent water seepage on the bathroom floor are the foundation of waterproofing, and the reasons for the ground water seepage are roughly as follows: the concrete base is not compact, the wall and the riser are not tightly bonded, the ground cracking caused by material problems, the shrinkage cracks caused by poor concrete maintenance and the gaps at the connection between the toilet and the flush pipe. In order to ensure the quality of the ground cushion, it is recommended to use 1:

Waterproof cement mortar, and focus on the treatment of transparent waterproofing agent or elastic waterproof coating (liquid) around the pipeline and concrete flanging place to improve the waterproof performance of the structure, and according to the design of 1% of the drainage slope, slope to the floor drain pipe.

D. The technical measures of non-seepage on the ground are well constructed, which can further help the grassroots to prevent leakage. At present, the bathroom floor generally requires the initial decoration, that is: the surface layer construction is completed by the residents themselves, and the residents are required not to destroy the waterproof layer, to ensure that the ground is not waterlogged, and the mortar should be full when the ground tiles are inlaid, so as to ensure that the inlay is dense and there is no hollowing phenomenon.

There should be no gaps around the connection with the pipe and the toilet and the corner of the wall, and it is best to use paper cement lime caulking between the water supply pipe and the casing, so as to ensure that the ground is not seepage.
