Should I vent the space between a block wall and vapor barrier?
I bought my house about a year ago and I recently took out 4 of the exisiting basement walls. 3 of which where exterior and 1 was just dividing the finished area and utilites. I found mold behind the wood paneling, sheetrock, 2x4 wood studs, and fiberglass insulation. The old walls were just about touching the block walls and had no barrior between them. I now am going to put 4 new walls up (same as before 3 exterior, 1 dividing). I use Drylok so far on all the exterior walls follwoing the instructions.
现在我计划安装一个蒸汽屏障使用6密耳塑料和保持新墙几英寸的块。我担心的是通过Drylok的湿气被蒸汽屏障阻挡了。我没有法式排水管，也没有任何排水管系统。我相信我说的是对的，砖块和屏障之间的空间必须呼吸才能让湿气变干。
我有一个想法，把除湿器由公用设施和运行管道工作(板水平)周围3墙)。我需要运行管道工作还是除湿器能够拉22英尺，使一个90英尺，另一个22英尺，再90英尺，然后再22英尺?顶部32英寸的块是外部，如果这使一个不同，我只是不想我的新工作被毁。另外，我从第一天就开始看了，我能看到的地下室没有漏水，演示之后下雨了，仍然没有水。
If I’m understanding you,keeping your poly vapor barrier away from the cinderblock wall won’t helpthe way you think it will, sincethere is no where to for the moisture to go. The reason being - if your walls are so wet / humid that water drains down them, then keeping an air space of an inch or so won’t do much to alleviate the problem, since that air will soon be fully saturated (as in reach 100% Relative Humidity) and the walls will then keep producing moisture or water at the same rate.
你考虑过在室内装个法式排水管吗?如果你沿着墙的边缘把混凝土弄碎然后放一个排水沟你可以把它引到一个水池水泵，这是最好的办法来管理大量的水积聚在地下室基础墙的内部如果这是你遇到的问题。
Blocks are very porous so they will absorb ground moisture and try to dry to the inside, but are you directing stormwater away from the foundation? That may held reduce the amount as well if you don’t already have it graded away from the house. If you don’t end up putting an interior French drain you may end up with problems, so at the least I would recommend you frame the new walls on foam blocks to lift the bottom plate off the concrete. It is less than ideal, but better to have that moisture drain out below the wall onto the concrete floor where it can evaporate and be handled by the dehumidifier. You can see an image of what I mean on the main photo of this page abouthow to prevent mold when renovating basements, which may be of value to you anyway.
在那篇文章中，您还将看到一张带有腐烂底板的砌块墙的照片，很可能是您所拥有的，如果您不小心，还可能再次拥有。你可以多问问题，我只是不太清楚你问的问题。
关于管道工作和除湿器的尺寸——我不确定我完全理解，但是——计算你有多少空气，确保你有一个足够大的，它们有不同的容量。我不明白管道的问题，请随意澄清。
