Do basements need drains, or does that let in Radon Gas?

Should I install basement drain tile vents?

我正在安装地下室排水系统，承包商想在墙体连接处的混凝土地板上安装通风口，将地下室墙壁上的冷凝水通过地板排到排水瓷砖上。他声称，这可以防止完工的墙壁后面形成霉菌。这是有效的还是仅仅是氡和地面蒸汽进入地下室的路径?
我不完全理解排水孔/排水孔的方案，承包商的具体方案是什么?你的意思是地板上要有一个排水孔，而他们建议在墙上设置一个排水孔或排水孔，让水排出，还是让空气进入墙壁组件，让水分蒸发?
A properly built wall should not have a condensation issue, so is this contractor about to finish your walls (and is anticipating failure) or is this a solution that the contractor is proposing for an existing wall with condensation issues? A floor drain will in no way prevent mold due to condensation inside walls, the only way to do that would be strip the walls and rebuild them properly. Here is a page that I think you (and perhaps your contractor) should read -
Why basements are moldy - how to fix & prevent mold in homes
We would love to help, and I think you could really stand for a second opinion before you move ahead, please give us more details and we can help you get on the right track, so let us know : if the walls are already built, when they were built, how they were built (placement and type of insulation, studs, vapor barrier), whether it's poured concrete or block foundation etc.. whatever you can tell us.
And yes, putting drains through the ground could contribute to higher radon levels, here is our page aboutmitigating radon gas in basements, have you ever tested for radon gas and are you in a high risk area?
我的描述是正确的，也是可以理解的。阻止地下水渗流通过concreete交界处的地下室层和基础墙七10采访承包商需要移除立柱墙,把地板到12英寸从基金会细胞膜,挖沟8英寸,安装一个排水瓦的页脚,油底壳,re-concreting排水瓷砖的地板用塑料通风管在基础墙让地下室墙凝结和渗漏流失到地板,穿过砾石到排水沟。如果没有通风口，该系统将不能保证保持地下室干燥。他们声称更换后可以防止螺柱墙后发霉。
你的第一个描述缺乏细节，Gary，有了额外的信息，现在可以理解了，尽管我觉得你的评论有点时髦，因为你是在寻求帮助，而我是在寻求细节，所以我可以为你提供帮助。
Proper drainage is essential for basements, so if it was not built properly in the first place then digging a trench along the interior perimeter to install a weeping tile and including ‘drains’ for water is a sensible idea if you have a high-water table or regular water infiltration into your basement.
If 7 of your 12 contractors recommend removing the stud wall, I assume they also recommend rebuilding the wall? How they build the wall and manage moisture will determine if there is mold or not, A floor drain may prevent bulk water accumulation and therefore slow the rot of the bottom plates but it will not prevent mold.
