We installed the system in my crawl space over last weekend. Yes, I am very satisfied with the product. And yes, I am very sore, head to foot, from crawling over rocks to install it. I'm glad I purchased the reinforced material (20 Mil GuardianLiner™).

This is a very nice liner that helps create a quality vapor barrier. Will purchase again for the next crawl space encapsulation I sell. Also, product came quick and this company has great customer service.

Received sump basin, Very well built and fits my needs at this time,I did give it all star rating as i believe it will hold up for a long time

Just used them and seemed to work fine. Easy install.

The large roll, 13.5' x 90', of silver back was easy to get into the house, cut and maneuver in the crawlspace. Easy enough for a DIYer.
