请问地下室底板底要做防水吗？ - 工程施工 - 项目管理 - 氿上知道

满意答案
4．3．3 卷材防水层用于建筑物地下室时，应铺设在结构底板垫层至墙体防水设防高度的结构基面上；用于单建式的地下工程时，应从结构底板垫层铺设至顶板基面，并应在外围形成封闭的防水层。
4．3. 3 在渗漏治理工程中，经常遇到有些工程地下室的卷材防水层只铺设外墙，底板部位不做，防水层不交圈，导致产生渗漏水。
因此本条强调：
1 附建式地下室采用卷材防水层时，卷材应从结构底板垫层连续铺设至外墙顶部防水设防高度的基面上。
2 外墙顶部的防水设防高度，应符合规范第3．1．3条的规定，即高出室外地坪高程500mm以上。
3 单建式地下室的卷材防水层应铺设至顶板的表面，在外围形成封闭的防水层。
