This is an extremely heavy duty product. I got it to put on some particularly heavy traffic sections of my crawlspace floor; elsewhere (floor and walls) the 12-mil product is more than adequate. The only two to consider are the 12-mil and 20-mil DrySpace.

This product appears to be everything it says it is. Time will tell. Would recommend this material to anyone for this application.

I was pleased to install the 12 mil at my customers request. It worked well. The customer is very pleased. I will continue to use this products on installs.

I noticed an immediate difference in air quality when the job was done. The 20 mil plastic is thick but easy to use. I do not know about durability as I just installed it. But it does tape together very well.

 

I have a space that is approximately 1,000 square feet in area and 5 feet in height. I wanted to use this space for general storage and storage of lawn equipment, so I needed a product to accommodate that. The floor was originally dirt which I leveled adding an average of 3 inches of 1B limestone to bring the floor up to the footer elevation. Based on recommendations from CrawlSpace Repair.com, I covered the limestone and footer with Felt 550 as an underlayment then finished with the 20 mil Silverback with string reinforcement. I ran the Silverback up the walls approximately 6 inches and secured it to the walls with Premium Encapsulation Caulking. I used the Waterproof ProSeam Tape on all seams following the proper installation procedures provided in the company videos. Finally, I attached one circulation fan to the ceiling and plugged it into a timer to promote air circulation. I no longer need a dehumidifier. The space is clean, dry and holds up to heavy foot and equipment traffic. I am extremely pleased with the products and the result.
