12 Mil Crawl Space Vapor Barrier, GuardianLiner™

Very pleased with the outcome of this project...This is a very superior product and the help I got in picking out the product was very very helpful

The product was better than anticipated. Very durable. I used the Felt 550™ underneath it. So far very satisfied.

Vapor barrier in the house was put in by the builder with 6 mill black plastic 28yrs ago, it was the usual shoddy job done by the builder, Last year noticed water pooling in the front area of the crawlspace, home is built on a sloping hill from front to back, front side crawlspace about 3 ft back side about 5 1/2 ft. Water was coming in from footer and under the footer, dug a french drain inside the crawlspace along the front wall and a sump pit with pump problem fixed. Decided to encapsulate the entire 1,800 ft crawlspace with 12 mill Guardianliner. This product is amazing extremely strong easy to work with, just measured and cut the pieces on the driveway and installed , used the foundation tape which has a excellent bond, I used foam board on all the walls and adhered with a strong water resistant epoxy. Overlapped 1 to 2 ft and tapped with the waterproof seam tape. The job turned out excellent, now understand I'm 64yrs old and had some great help from my college graduate daughter, but it did take about 5 months to complete, included running additional wiring for lightning and french drain and pump plumbing. however the end results looks like a NASA clean room. Humidity level before project was 75 to 80 percent after completion 45 to 50 percent and this is with a Dehumidifier that was made for a basement, it barely runs because the crawlspace is sealed off however still enough air for furnace to run. This company offers the best products made for the job do it right the 1st time and never worry about it again.

This stuff seams to be of good quality Easy to work with and came in sizes that worked well with the dimensions of my project

This product has factory seam in middle of sheet. The first half of roll had quality seam and was a quality product. The second half had seam was delaminated and not a quality seal. I had multiple issues with another order so I did not pursue corrective action after 1st experience. Customer service unacceptable for returns, difficult to work withand they were they were slow to resolve.
