您好，感谢您回顾我的问题/困境。我正在完成我的未完成的混凝土浇筑地下室在我的2550平方英尺的牧场住宅建于2002年。根据GreenBuildingAdvisor的文章，我用2个″EPS直接粘在墙上的方法来绝缘我所有的墙。这部分我已经完成了70%。我已经利用罐装喷雾泡沫绝缘之间的似乎4'x8 '面板和特维克胶带。我已经修复了所有的地方，我有水渗入头发线裂缝的基础墙在过去。想想看，在一个月的时间里，我把绝缘材料固定在一堵从来没有水问题的墙上，结果发现了一小滩水。我最初的计划是将2个″EPS从地板搁栅顶部粘到地板底部。地板采用1个″厚硬泡沫与2个″墙体EPS对接。在1″硬质泡沫地板上加胶合板。 However, here is my dilemma, I have subscribed to the wisdom of having the thermal break and air sealing by utilizing 2″ EPS on the walls, and intended on doing the same with the 1″ rigid foam on the floor, BUT, after seeing the water seep through on a wall that previously never had any water issue I have realized that water is going to come in to the basement in some occasions. So if I did the sub-floor with gluing the Rigid foam directly on concrete basement floor then I am giving the water that gets into the basement through the walls no where to go. If enough water was to come in a particular spot and had no where to go, I suspect the water pressure could increase enough to begin penetrating the seems of the EPS, or even pop the insulation off the wall over time. Or if it does find a way to get above the rigid foam on the floor it would then be very close to plywood sub-floor and could possibly saturate bottom plate of framing. SO my solution that I have come up with mentally is to utilize a dimple plastic underneath the rigid foam, tuck it about an inch underneath the 2″ EPS on the walls. This way any water that comes in through the walls would be directed underneath the dimpled plastic. The little bit of air flow provided by the dimpled plastic would eventually allow the floor to dry or absorb the moisture through the concrete. OF COURSE this goes against the whole wisdom behind air sealing and creating a thermal break on the concrete basement floor ensuring no condensation. But I think this is the only way of ensuring water that occasionally comes in through the walls has a place to go without destroying the finished basement.
你们觉得怎么样?谢谢，很抱歉我的问题太冗长了!
