The materials were of high quality and worked as advertised. I used the 20 mil SilverBack over 5100 42.

High quality and strong product. Very pleased with it.

Got a quote from a company to install this system for me for $6,700! I went to Crawl Space Concepts after researching several vapor barrier products and ordered everything I needed for $1,200 including shipping. Installed the entire system in my crawl space in 2 days. The products were all exactly as described, high quality, easy to use, and relatively inexpensive. I am VERY pleased with the final results and thanks to Crawl Space Concepts, I saved $5,500!!

I purchased the 20 Mil liner for my new construction crawl space and had it installed and then sealed to the walls by a reputable spray foam company. They and I are were impressed with the product. The crawl space has extremely low humidity since installation. The liner seems very durable. I am happy with the choice.

Outstanding product, and customer service and it's made right here in the USA love it. Received the product in 2days with no shipping charge. Bought this product as a vapor barrier in my shelter logic outdoor shelter. It worked great at keeping the moisture from coming up from the ground. Very happy with the product quality. Would not hesitate to do business with Crawl Space Repair again in the future. Robert in customer service was very helpful. Thanks again, Paul.
