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!

This tape is excellent at sealing the vapor barrier seams together. It is very sticky and strong. Once its on the vapor barrier, its almost like it becomes part of the barrier.

Was suprised at the size of the rolls when I recieved them--4 inch across. product is quite thick and durable. easy to use. found it helpful to make sure surfaces were free of any dirt or debris before applying. arrived quickly.

I was very pleased with the quality of materials and the relative ease of installation. You get high marks for quality, service, and an excellent website.
