I purchased the foundation pins along with all of the other materials to encapsulate my crawl space. All of the products worked better that I expected and I accomplished the job with no assistance due to the quality. It is a real pleasure to use American made products again! Thank you for the help!

All materials and supplies were as advertised. The foundation tape, the water proof seam tape, and the vapor barrier fasteners worked exactly as advertised. I could not have been more pleased with the products.

Just finishing encapsulating our crawl space. Used the 12 mil diamondback, butyl tape, seam tape and foundation pins and couldn't be more satisfied. Work as promised and we were surprised how easy the 12 mil was to work with. Appreciated the helpful info on the website and even more the direct customer service. Called two or three times with questions and always got someone who was very helpful. Thanks again! Good to be almost done and even better to think we shouldn't have to do this again with quality products like these!
