地下室渗漏主要存在于施工缝、伸缩缝、后浇带、外墙等部位，主要是这些部位处理不好而产生的渗漏。施工缝浇筑砼前按常规方法处理，把表面凿毛，止水钢板清理干净，浇水湿润，浇筑时先用同强度等级石子砂浆接浆，保证施工缝接触良好。地下室是承受房屋全部荷载并将荷载传递到土层上去的承重基础部分，对房屋的安全和使用年限具有重要意义，而且地下室本身也有着很重要的使用功能。随着我国建筑技术的发展，地下防水技术也取得了令人瞩目的成就，用于地下防水工程的材料己从少数品种发展为多类型，多系列的格局，地下室防水构造也由过去的单一型式发展为当前的材料防水与构造防水相结合，刚柔材料相结合等新的形式。
1、地下室防水第一要做到的结构自防水，就是地下室混凝土防水等级要达到一定标准，比如混凝土抗渗等级大于P8，地下室混凝土底板的防水需要做刚性和柔性多道防水。
Basement Waterproofing first to do structural waterproof, waterproof concrete basement is to achieve a certain level of standards, such as concrete impermeability grade greater than P8, waterproof basement concrete floor needs to be done rigid and flexible multi-channel waterproof.
2、地下室裸露顶板的防水，地下室顶板混凝土浇筑完成后，做30mm厚c25以上细石混凝土内掺水泥用量10%抗渗微晶防水剂进行找平，再做911聚氨酯防水涂料一道，再做4mm厚SBS卷材一道，再在卷材上面做混凝土保护层，再在上面铺设地砖的装饰层。如不做地砖等装饰层，SBS卷材裸露，上面就不做任何东西了。
Exposed roof waterproofing basement, basement ceiling after concrete pouring is complete, do the 30mm thick concrete mixed with fine stone c25 above 10% impermeability microcrystalline cement waterproofing agent for leveling, do a 911 polyurethane waterproof coating, do 4mm thick SBS Volume material one, and then do the above in the web of concrete protective layer, and then laying floor tiles on top decorative layer. As do floor tiles and other decorative layer, SBS membrane exposed above do not do anything.
3、地下室顶部开裂渗漏水属于典型的结构型渗漏水。可采用“钢柔相济，多道设防”的治理方法，即采用嵌填弹性密封材料与钢性防水材料相结合，最大限度地利用这些材料的特长，形成复合防水层，使已修补的裂缝不再受沉降变形等因素的影响而再度开裂渗漏。使用机械灌浆的方法，利用灌浆材料遇水高度膨胀的原理，使原来疏松的水泥结构组织变得密实，从而阻止地下水的渗入。达到防水防渗的效果。
Cracking the top of basement water leakage is a typical structural leakage of water. Can be "soft steel with mercy, multi-channel fortified" governance approach, which uses elastic sealing material filling them with steel waterproof material combined expertise to maximize the use of these materials to form a composite waterproof layer, so that the cracks have been patched no longer affected by factors such as settlement deformation and cracking leaking again. Mechanical grouting method using water filling material highly inflated principle, the original loose cement structure becomes dense tissue, thereby preventing groundwater infiltration. Achieve the effect of water seepage.
3、改性环氧树脂灌浆液是用某种普通环氧树脂为改性主剂，采用高科技手段，在该树脂的部分端基嫁接亲水性基团，使普通环氧树脂形成一种具有亲水性和亲油性的新型树脂，用这种两性树脂配以增塑剂、促进剂、固化剂等配制而成的一种高强度的、能在有水混凝土裂缝进行补强化学灌浆的新材料。
Modified epoxy grout is of a general epoxy resin as the main agent modifying, using high-tech means, in the portion of the end groups of the resin grafted hydrophilic groups, so that ordinary epoxy resin having an affinity aqueous and lipophilic new resin, with this gender resin with plasticizer, accelerator, curing agent prepared from a high-strength, water can be reinforced concrete crack new chemical grouting material.
4、地下室墙板混凝土浇筑完成后在墙板外侧做APP卷材或SBS卷材或911聚氨酯防水涂料（3种防水材料选一种即可），地下室墙板外侧防水完成后，用聚苯板保护回填土，那样就算地下室墙板外侧防水完成了。
After the completion of the concrete pouring basement wall on the outside wall doing APP or SBS membrane or membrane 911 polyurethane waterproof coating (three kinds of waterproof material to choose one), after the completion of basement waterproofing the outside wall, backfill with polystyrene board protection soil, so even if the outside of the basement wall waterproofing is complete.
