绝缘地下煤渣块墙
大家好，
我的名字是迈克和我目前计划鳍ish my basement in Michigan. My basement walls are hollow cinder block and I plan to paint the with drylock or a Ames block and wall liquid rubber paint (not sure which yet) to prevent moisture from seeping to the interior. Following this, I plan on putting 2in of rigid foam insulation (eps) on the basement wall followed by the studs. I plan on keeping the space between the studs as air space in front of the rigid foam for electrical and plumbing. I was told by my contractor that it’s best not to insulate the basement wall to allow the cinder block to dry to the inside. He said that if I put rigid foam insulation it won’t allow the cinderblock to dry and may result in a mold issue. Most of what I have read said to use rigid foam insulation.
我已经阅读了有关该论坛上绝缘地下室的大多数文章，但想了解有关此特定问题的一些其他建议。.如果使用使用煤渣块的干锁式密封剂，则可以阐明一些建议，然后2英寸的泡沫会导致一个霉菌问题，甚至裸露的煤渣块上的刚性泡沫是否会引起霉菌问题？
In addition to that, I have read that adding rigid foam insulation to cinderblock wall could cause the cinderblock to freeze in the winter cause cracks in foundation. Is this true?
提前致谢。

The mold is a non-issue, if mold is going to form it's going to be on the other side of the moisture barrier and not connected to your living space. The dirt on the other side of the cinder block is full of mold, but you don't worry about it because there's not way for it to get into the house.
砌体保持潮湿和冻结时的损坏是真实的。的确，绝缘的内部使墙壁的地上部分较冷和湿。我读了有关地下室隔热时被破坏的历史砖砌建筑的故事。我没有关于如何预防它或确定在您特定情况下的风险的任何建议。
我将添加一个附录，因为只有当块或砖被弄湿然后冻结时，这种损坏才会发生。也许是一个小细节，但是如果它们保持干燥，感冒很少。
Thanks for the info. I am fairly certain our cinder block gets wet here in michigan, it rains/snows quite a bit.
挖掘外部和防水，然后使用刚性板绝缘材料阻止任何冻结问题吗？在这种情况下，在煤渣块的内侧和外侧都有绝缘。
如果是这样，需要什么厚度的刚性泡沫板？
Thanks
Excavating and cleaning the foundation and then adding waterproofing and rigid insulation is the gold standard for foundation treatment and it would certainly minimize any chances of frost damage. It is not cheap though. The most important thing is to manage water on the exterior of the foundation by using good grading for runoff, a drainage layer in the backfill (dimple mat if not using fibrous or other self-draining insulation), and footing drains routed to a sump pump or daylight. If you go this route, a 50-50 mix of insulation inside and outside would be more than adequate. 2" applied both in and out would give you about R20, which is very good for foundation insulation in your climate.
也就是说，即使在非常潮湿的批次上，iMvho冻结自行车损坏的风险也很低。我已经看到了非常古老的CMU损坏，该CMU使用煤炭煤石公司进行了骨料，但自1970年以来就没有生产任何块。
借助良好的外部防水，您不需要干燥锁或内部。不，内部的刚性泡沫不会导致霉菌的生长。实际上，如果您使用箔面的polyiso绝缘材料并将接缝胶带胶带，则大大降低了霉菌生长的风险。确保气封并隔离带托梁，并将这种处理与内部泡沫联系起来，以获得最佳效果。
我的房子建于1951年，所以我认为正如您所说的那样，它是煤渣。在这种情况下，您会说如果我只在内部隔离，这会有风险？
还有一些问题：
1.如果我防水外部粉底，我会使用焦油或防水涂料的地方，然后用刚性板上的木板涂上焦点？
2. Could the drain pipe connect to city pipes?
3.如果挖掘外部的挖掘价格过高，如果我只在内部放置绝缘材料，可以保护煤渣块不受破解的替代方案？
