I've put the 12mil silver back on my concrete walls and 20mil on the ground in my crawl space . Very satisfied with both products . Thank you crawl space repaire .

I had quotes from multiple big companies to "encapsulate" my 1945 dirt and damp basement with only 6ml plastic. A true encapsulation wouldn't work in my basement, and would only increase the risk of termites. I chose this product after researching various plastics and reading studies on different levels of VOC toxicity. My handyman did a great job cutting to fit and used tape and a few round crawlspace stakes to fasten to the dirt banks. Very happy with the result, I have a much higher quality vapor barrier for a fraction of what the larger companies were going to charge.

Excellent products. Everything purchased was just as described and worked perfectly. Thank you!

Very pleased with this vapor barrier-much higher quality than the one originally installed when our home was built.

I cannot recommend this product enough. We installed it in our crawl space after the Colorado floods in 2013. After installing it, our crawl space has been warm and dry and we have had no mold issues. I was hesitant to use the foundation pins, but the person we talked to said we really needed them, and he was right. We were able to rent a "pin gun" from our local hardware store and the combo of the pins plus the caulking has held up extremely well. In this day and age of bad customer service and poor quality products that look good but don't deliver, it is nice to find a product that does what it says it will and exceeds your expectations. Highly recommend.
