地下室底板、垫层外表及内外墙批20mm厚屋顶防水砂浆后，做1.2mm厚BPS高强屋顶防水防腐密封涂料作为填补和完美，以完成刚柔并重，多道设防。按标准请求合理规划施工缝和沉降缝也是抗渗防漏的一个亮点。
Barrier, basement floor, cushion appearance and inner wall 20mm thick waterproof mortar after 1.2mm thick BPS high strength waterproof anti-corrosion coatings sealed as perfect, and to complete the rigid flexible, multiple protection. According to the standard request for reasonable planning of construction joints and settlement joints but also a bright spot in the anti leak.
防水在新浇筑混凝土前应作如下处理：
The waterproof should be treated as follows in the new pouring concrete:
（1）铲除接缝外表的水泥浮浆、薄膜、软弱混凝土层、油污等；
(1) cement grout, film, soft concrete layer, oil stain, etc.;
（2）将钢筋上锈斑及浮浆刷净；
(2) the steel rust and mud brush;
（3）用水清洁后铺上高标号的水泥浆。当然，除了施工的需求、天气的影响、机械设备毛病等人力不行抵抗的要素外，尽量少留或不留施工缝，如许对于构造的全体性也很有益处。沉降缝是为克服构造不均匀沉降而设置的缝，须从基础到上部构造彻底分隔。
(3) high grade cement paste after cleaning with water. Of course, in addition to the needs of the construction, the impact of climate, mechanical equipment, such as the human elements of the elements do not resist, as far as possible to stay or do not leave the construction joints, so for the construction of the whole is also very good. The settlement joint is set up to overcome the uneven settlement of the structure, which must be separated from the base to the upper structure.
施工过程：
Construction process:
（1）将沉降缝内原添补物除掉必定深度，并进行整顿；
(1) remove the original filler from the settlement joint to a certain depth, and arrange it;
（2）用抗渗资料（堵漏型）先止水，嵌填挤塑板并灌浆；
(2) with anti infiltration data (plugging type) before sealing, filling and grouting of extruded plate;
（3）用抗渗资料（堵漏型）封孔关键词优化，外侧再次嵌填挤塑板并留孔，与其构成一空腔，灌注PU止漏胶，添补密实；
(3) with anti infiltration data (plugging type) sealing, filling the extruded plate and outside again, leaving a hole, and form a cavity perfusion PU leakage stopping glue, filling;
（4）缝内嵌填抗渗资料（屋顶防水型）（网站排名），并做隔离，然后全体嵌一道PU密封胶古建方砖，并与缝外表平齐，构成一道柔性止水带；（5）缝处做隔离层，两侧涂刷湿润基面封闭剂，然后涂刷PU屋顶防水剂。另有需要留意沉降缝的设置宽度不该少于120mm,沉降缝还有需要写意抗震缝请求。
(4) joint anti permeability data embedded in fill (waterproof), and isolation, then all embedded a PU sealant, and seam surface flush, a flexible sealing strip; (5) joints as isolation layer, moist surface coating on both sides of sealant, and then brushing waterproof agent PU. Otherwise it is necessary to pay attention to the width of the gap should not be less than 120mm, there is also necessary to meet the requirements of the settlement joints.
