   只有在膜上有一些东西以允许凹坑提供排水间隙，才有助于提供自由排水（雨）。一种良好的防水应用直接放在混凝土上（不薄的“潮湿”）将避开水，虽然它是良好的做法与多孔的东西回填，如沙子。对凹膜的一层刚性泡沫将提供排水间隙。然而，为了绝缘目的，泡沫应该达到窗台，因为等级以上的基础看到最寒冷的冬季温度。将泡沫带到窗台介绍了保护它免受紫外线和物理损害的必要性。然后，也是泡沫延伸超过壁板的平面的泡沫的问题，因此需要闪存它。在我的房子里，我把2“在我的基础之外，然后再来2”里面。因此，我必须保护外部泡沫（我使用的表面粘合水泥提供耐用），而且我必须保护内层以保护用于防火。如果我不得不再次做房子，我就会把里面放在里面的所有绝缘，在它上面的火焰保护，我无论如何都要做。

   鸡巴，
   膜上的凹陷，如delta制造的那些，不需要额外的盖子。凸块提供固体塑料表面和混凝土之间的间隙。

   Dick/Malcolm,

   Thank you for your insight. I'm in zone 5, and this is exactly what I am struggling with now. I know in the future we will finish the basement, which will require us to potentially insulate on the inside based on if/or how we insulate on the exterior. I fear damage to the exterior foam, or my husband getting frustrated with it and just cutting it to grade and flashing it, which which will impact interior insulation requirements.

   我正在考虑在外观上施加2“，假设我们仍然需要在内部隔离，而且更糟糕的是，基底比我没有在外观上放置任何东西。

   马尔科姆,我勒arning that there are 'dimple' membranes and 'dimpled' membranes. Based on the type used, does the foam go to the interior or exterior of the membrane?

   尼娜，the issues stated above are exactly why I prefer, when possible, to insulate foundations on the interior. An elastomeric waterproofing compound on the exterior is important if you want a dry basement, and a dimple mat is good insurance. Thermax-brand foam insulation is usually allowed to remain exposed on the interior, but it's not inexpensive and can't be used to cover another, cheaper insulation. Another option is to spray foam the interior of the foundation, preferably with a product that has low global warming potenial, such as Lapolla's Foam Lok 2000 4G or Demillac's Heatlok XT HFO.

   尼娜，
   Some installers sandwich the dimple mat between the concrete wall and the rigid foam. Other installers put the dimple mat on the exterior side of the rigid foam (between the rigid foam and the backfill).

   The detail below shows the latter approach. It comes from the Building America Solution Center.

   迈克尔，谢谢，我正在考虑喷雾泡沫选项，特别是因为它不需要立即发生。

   Martin, Thank you for the diagram, I have been looking for one all weekend. Do you think the decision to put the membrane on the inside or outside typically depends on the the type of membrane used (rigid/exterior to foam or the peel -n- stick/interior to foam)?

   尼娜，
   Peel-and-stick is not a dimple mat. If you are using a peel-and-stick product, it goes on the concrete.

   如果您使用的是凹坑垫，它可以抵靠混凝土（假设没有剥离和粘贴），或在剥离和粘附和刚性泡沫之间（假设您使用剥离和粘贴），或在刚性泡沫的外侧，如我发布的图示所示。

   尼娜，

   My vote is to insulate from the inside too. I just went through a foundation pour a few months ago and I avoided a whole bunch of issues by choosing to insulate from the inside. I plan on placing 4" of EPS sub slab and 2 1/2" on the walls. I have been eyeing a product by Insofast and while I see them at all the trade shows, I finally decided to buy some to test it out - see pics. What I like about this product is that it is easy to install, it has electrical raceways built in, and it has plastic studs every 16" OC that you can screw the gypsum directly to so no need to create an interior wall for the gypsum. It is not cheap (pricing is on their website), but it is a DIY friendly product.

   谢谢你的澄清马丁。

   乔纳森，这是一个有趣的产品，绝对值得我研究时间;谢谢。我们打算将板坯的两侧与2英寸的泡沫隔离。您是否会看到使用该产品的任何问题，我们应该这样做吗？

    Martin，我很兴趣地做到你共享图片中所示的（评论＃5）。你如何假设凹坑垫被固定？细节在附加的车库底板下面会看起来像什么？
