地下室底板、墊層外表及內外墻批20mm厚屋頂防水砂漿后，做1.2mm厚BPS高強屋頂防水防腐密封涂料作為填補和完美，以完成剛柔并重，多道設防。按標準請求合理規劃施工縫和沉降縫也是抗滲防漏的一個亮點。
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.
防水在新澆筑混凝土前應作如下處理：
The waterproof should be treated as follows in the new pouring concrete:
（1）鏟除接縫外表的水泥浮漿、薄膜、軟弱混凝土層、油污等；
(1) cement grout, film, soft concrete layer, oil stain, etc.;
（2）將鋼筋上銹斑及浮漿刷凈；
(2) the steel rust and mud brush;
（3）用水清潔后鋪上高標號的水泥漿。當然，除了施工的需求、天氣的影響、機械設備毛病等人力不行抵抗的要素外，盡量少留或不留施工縫，如許對于構造的全體性也很有益處。沉降縫是為克服構造不均勻沉降而設置的縫，須從基礎到上部構造徹底分隔。
(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.
施工過程：
Construction process:
（1）將沉降縫內原添補物除掉必定深度，并進行整頓；
(1) remove the original filler from the settlement joint to a certain depth, and arrange it;
（2）用抗滲資料（堵漏型）先止水，嵌填擠塑板并灌漿；
(2) with anti infiltration data (plugging type) before sealing, filling and grouting of extruded plate;
（3）用抗滲資料（堵漏型）封孔關鍵詞優化，外側再次嵌填擠塑板并留孔，與其構成一空腔，灌注PU止漏膠，添補密實；
(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）縫內嵌填抗滲資料（屋頂防水型）（網站排名），并做隔離，然后全體嵌一道PU密封膠古建方磚，并與縫外表平齊，構成一道柔性止水帶；（5）縫處做隔離層，兩側涂刷濕潤基面封閉劑，然后涂刷PU屋頂防水劑。另有需要留意沉降縫的設置寬度不該少于120mm,沉降縫還有需要寫意抗震縫請求。
(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.
