卫生间防水闭水试验怎么做

卫生间防水闭水试验,最怕赶工只泡几个小时就放水。表面看没漏,不代表墙根、管根、门槛石位置都稳。以前见过一个卫生间,闭水时间太短,楼下没反应就贴砖了,入住后淋浴区门口慢慢返潮,最后拆地砖查才发现门槛处防水收口没做好。 我现在会先看基层有没有空鼓和尖角,管根、阴角先做加强,地漏坡度别被防水层糊平。闭水高度要够,门口挡水要封严,最好满 24 到 48 小时再看楼下和相邻墙面。墙面淋浴区也别只做半高,实际花洒水会溅得比想象远。 如果地暖、移门轨道、壁龛这些细节没提前处理,防水层很容易被后面工序破坏。贴砖前还要再看一次有没有被踩破、割破。排水口临时堵头也要看紧,别闭水时自己慢慢漏掉。你们闭水试验是自己拍照留底,还是让业主和楼下邻居一起确认?
