I would like to thank CrawlSpace Repair again for all of their help. I don't think I would have attempted this without their good advice. This saved me at least a couple of thousand dollars, I'm sure. The bonus is that the finished basement area is now cool and dry so we can finally use it to store stuff. Life changing... I've already recommended CrawlSpace Repair to several friends.

Like the felt very durable and looks great

The 12 mil is a really great product.

20 mil is a good strong durable product

My 600 sq ft metal building has a dirt floor and suffered from high humidity leading to mold and mildew. I placed the 20 mil with the silver side up, taped it to the metal frame and placed pins about every 18 inches. It looks great and has dramatically reduced humidity. An excellent product. I do suggest that when drilling the holes in the metal frame that instead of drilling 1/4” it was better to drill 7/32” holes. It made the plastic pins tighter.
