The basement itself is a relatively dark and damp place, so waterproof construction in the basement must be done in particular. The inner and outer walls that are connected together in the basement must be poured together. The outer wall is self-waterproof, and all the two vibrating techniques are used. The following small series introduces the steps of basement waterproof construction . Basement waterproof construction steps - material preparation Prior to the waterproof construction of the basement, the corresponding waterproof material should be prepared in advance. The main waterproof materials are: polyurethane waterproof coating, polyester fiber non-woven fabric, polystyrene foam board, etc., and to ensure that the waterproof main material content, strength, flexibility and impermeability, etc. meet the construction requirements. In addition to these main materials for waterproof construction, auxiliary materials need to be prepared. Examples include xylene (diluents and machine cleaners), dibutyltin dilaurate (coagulant), and benzenesulfonyl chloride (retarder). Major construction Tools include electric mixers, mixing buckets, paint brushes, and spring scales. Fire equipment and so on. ·Basement waterproof construction steps - base treatment When performing waterproof construction, it is necessary to ensure that the basement and walls of the basement meet the construction requirements. Therefore, the basement should be thoroughly cleaned before construction to ensure that the base surface is clean and tidy. · Basement waterproof construction steps - waterproof layer construction After preparing the materials and tools, the waterproof layer was cleaned and the construction of the waterproof layer started. The Xiaobian reminded that because the waterproof construction of the basement is a negative pressure construction, the construction is difficult, so it should be professional and experienced. The professional construction personnel carry out the construction. 1, the deployment of paint The waterproof layer of the grass-roots level is formed by waterproofing membranes. Therefore, when waterproof construction is performed, the paint must be prepared according to the design requirements of the basement. If the waterproof design of the basement does not have specific provisions for the deployment of the paint, it needs to be carried out according to the general deployment ratio. . 2, waterproof layer construction The specific operation steps are as follows: To prepare a good mixed paint, evenly brush on the substrate with a squeegee or a roller brush. Generally, it needs to be brushed 3-4 times, because the waterproof layer smearing standard is not less than 2mm, so in each Once coating, there are strict rules for the amount of coating, which is generally 0.8 ~ 1.0kg/m2 in the plane base layer and 0.5 ~ 0.6kg/m2 in the opposite base layer. 3, isolation layer and protective layer After the waterproof coating is applied, the waterproof layer needs to be protected and isolated. This is to make the waterproof layer more durable. Generally, the plane base layer should be evenly sprinkled with fine sand as the isolation layer. Afterwards, the application machine placed fine stone concrete on the fine sand isolation layer as a rigid protective layer. During the construction, attention should be paid to the destruction of the waterproof layer during pouring. If the waterproof layer is damaged during construction, it must be repaired with the polyurethane mixture in time. 4, the final treatment After pouring the concrete rigid protective layer, it is necessary to make a soft protective layer on the rigid protective layer. Generally, it can be paved with foam plastic material to ensure that the waterproof layer is destroyed when the ash soil is backfilled.
