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.

I would like to thank CrawlSpace Repair again for all of their help. I don't think I would have attempted this without their good advice. This saved me at least a couple of thousand dollars, I'm sure. The bonus is that the finished basement area is now cool and dry so we can finally use it to store stuff. Life changing... I've already recommended CrawlSpace Repair to several friends.
