Therefore bathroom waterproofing is very important to do well. Here and we will look at the bathroom waterproofing acceptance criteria and the causes of leakage.
Bathroom waterproofing acceptance criteria
A, the purchase to recognize the name brand: At present, the market is flooded with crooked goods, the state explicitly eliminated, banned toxic materials also flooded into the people’s homes. The average consumer should choose high-profile, good reputation, high degree of anti-counterfeiting, international quality system certification of brand products.
Second, waterproofing parts to be comprehensive: bathroom floors and walls (not less than 1.8 meters or full do), kitchen, balcony floors and walls (not less than 0.3 meters), all ground and walls of the first floor residential (0.3 meters), basement floors and all walls should be waterproof, moisture treatment.
Third, the thickness of the waterproof layer to be enough: the thickness of the waterproof layer directly affects its waterproof life, if you reduce the thickness of the waterproof layer is equivalent to reduce its waterproof life.
Fourth, the construction process to be meticulous: the wall and the ground joints, yin and Yang corners, water pipes, floor drains and sanitary ware around and laying hot and cold pipe chisel trench is the key waterproofing parts, construction must be meticulous.
Fifth, after completion of the closed water test: waterproofing construction is completed, seal the doorway and downspout, indoor water storage for 24 hours, check whether there are leaks.
Analysis of the causes of leakage in the bathroom
A, pipe node leakage management analysis. The first treatment method is the front waterproofing treatment, but if the excavation is carried out after the decoration, will damage the decoration, bringing certain losses to the user. The second treatment method is to deal with the back, this method is technically difficult, requiring a certain level of professionalism and technical support. This method has less loss to the user. For the more stubborn seepage node for back treatment, firstly, along the pipe node around the cut a finger width deep, pre-buried grouting tube; then use W3 type water stopper for priming; then use D1 anti-seepage mortar for sealing, Q4 special grouting liquid for grouting treatment before sealing; finally in the surface layer using W2 node adhesive for coating, the range according to the diameter of the pipe 1.5-2 times the Diameter, coating thickness of not less than 3 mm. with the method can ensure that the long-term waterproofing purposes.
Second, the pipeline well water seepage management. Now a typical pipe well leakage caused by a long period of dripping ceiling for the analysis of cases, upstairs pipe well water, there are a variety of reasons, may come from the roof, water pipe leakage, the upper layer, and then the upper layer, and even ten layers above the user’s bathtub bottom water leakage. Our treatment method is to use special grouting machine to carry out equal pressure grouting treatment after temporary blocking at the bottom of the floor, and to set equal pressure holes in the upstairs pipe wells. After this treatment, generally can achieve long-term waterproofing purposes.
Third, the root of the wall leakage management analysis. As a result of decorating the ground, so that the aisle and toilet flooring to reduce the difference, coupled with unreasonable tiling method, resulting in water seepage from the wall, and even the floor warped and deformed. Our treatment method is to open an area not less than 100mm wide and high at the root of the wall, and reach the structural layer. Then use D1 impermeable mortar to deal with the root, not to miss, once completed, no hew, and finally restore the floor tiles. Using this method can effectively achieve water-proof.
Fourth, the analysis of leakage management of sub-chamber wall. This situation is mostly manifested as water seepage, mildew, paint peeling, stucco drums on the wall of the sub-chamber wall adjacent to the toilet. To decorate the exquisite bathroom, for example, the eradication of tile processing loss is too large, does not allow the front again to do waterproofing, can be processed in its backwater surface. The method of treatment is to remove the moldy wall painting layer, D1 impermeable mortar scraping brown, the root of the grout, with Q1 wall impermeable mortar 10mm, in about 15 days, to put forward the wall moisture and wall dry, can be restored to decorate. The treatment can ensure the permeability of the wall and inhibit capillary penetration.
