原因分析 Reason：
(1)混凝土、砂浆施工质量不良，存在微孔渗透；
(1) the construction quality of concrete and mortar is bad;
(2)板面、隔墙出现轻微裂缝：
(2) the board, partition slight crack:
(3)屋顶防水涂层施工质量不好或损坏。
(3) poor quality or damage of waterproof coating.
堵漏措施 Plugging measures:

(1) removal of decorative materials, exposure to water seepage, coating waterproof coating. In addition to polyurethane waterproof coating, usually with fiber materials to repair.
(2)如有开裂征象，则应对裂缝进行加强屋顶防水处理；贴缝法：对细小的发丝裂缝，可刷屋顶防水涂料并加贴防水聚酯布，作屋顶防水处理；填缝法：若较显明的裂缝，要进行扩缝处理（北京设计），将缝扩展成15 ×15mm左右的V型槽，在清理干净后（河南人事考试），刮填屋顶防水涂料或嵌缝材料；填缝加贴缝：除采用填缝法处理外，在缝外观再涂刷屋顶防水涂料，并粘贴防水聚酯布处理。亦可不拆除饰面，直接在其外观刷涂纯丙烯酸屋顶防水涂料。
(2) if there are cracks, cracks should strengthen waterproof treatment; mount joint method: tiny hair crack, can brush waterproof paint and add fiber material or cloth, waterproof treatment; filling method: if the crack is obvious, to enlarge the joint treatment, will be extended to V type groove joint about 15 * 15mm, in clean, scraping fill waterproof coating or caulking material; filling affixed by caulking seams: in addition to treatment, the joint surface waterproof coating is coated, and paste fiber material processing.
