Basic waterproof technology measures In the construction of the bathroom cast-in-place board, according to the design of the bathroom wall position, on the board to do a return to the 60mm high, width 60mm ç ¼ stop the water, construction and cast-in-place board at the same time, and set aside all kinds Pipe holes, to avoid drilling holes in the floor afterwards, leaving hidden water seepage problems; floor concrete must be vibrated and compacted during construction, especially around the pipe and corners, must be leveled to avoid uneven, quality inspectors should strictly control the quality The unqualified office must be reworked. Technical Measures for Preventing Water Leakage on the Floor Cushion Non-seepage of the bathroom floor is waterproof. The causes of ground water seepage are: the concrete base layer is not dense, the wall surface and the riser are not tightly bonded around each other, the ground crack caused by material problems, and the concrete curing is not Well caused shrinkage cracks and gaps between the toilet and flush pipe joints. In order to ensure the quality of the ground cushion, it is recommended to use a 1:2.5 waterproof cement mortar on the design, and use a transparent waterproof agent or elastic waterproof coating (liquid) at the periphery of the pipe and the flange to improve the waterproof performance of the structure. Design a 1% discharge slope and drain pipe to the slope.
The technical measures of surface imperviousness and good construction of the surface layer can further help the base layer to prevent leakage. At present, the bathroom floor generally requires early decoration, that is, the surface layer construction is completed by the tenants themselves, and the households are required to not damage the waterproof layer. To ensure that the ground is not filled with water, the mortar must be full when inlaying the floor tile to ensure that the inlay is dense and dense and there is no emptying phenomenon. exist. There should be no gaps between the junctions of the pipe joints and the toilets and around the corners of the walls, and it is best to use paper cement lime joints between the water supply pipes and the casing so that the floor can be protected from seepage. In fact, as long as strict construction in accordance with the norms and regulations, checks at all levels, you can make high-quality qualified projects, let the people live in the house, while creating good economic and social benefits for the company.
