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.
My husband and I just completed our crawlspace encapsulation project using the 20ml Guardian Vapor Barrier from this website. It was a grueling job (not recommended for 58 and 60-year-olds) but we got it done. It took several weekends some weeknights, but well worth it. Humidity has already dropped 35%. Our next step is installing air ventilation system then we feel our foundation will be secure. A tip I would offer is to consider coverage of your crawlspace walls when ordering materials. Our house is about 1800 sq feet so I ordered two 1,000 sf rolls, but because of all the wall space and support pillars that needed to be covered I ended up needing to order an additional 1,000 sf roll to finish the project. So glad it's done!
great product just wish when rolled from manufacture that there were no creases.all the materials i received were of top quality and easy to place. just one word of caution, buy the felt backer also. i placed mine on 1/8th" limestone chip and it seems like it could poke through the liner. but all in all great product.
The liner was really strong and easy to work with because it was so durable. It is rigid enough to move all as one unit once you have it spread on the ground. The only issue was first getting started because the 1000 square foot roll weighs 100 pounds so its hard to manage at first.
I am very satisfied with the quality of the liner. The service from Crawlspace Repair is outstanding.
Vapour barrier laid down super easy even in a tight space. It was easy to maneuver over the felt 550. Planned out the pieces and cut them in the garage to make transportation into the crawl space easier. Only installed a few days, but the musty odor is gone from the house & crawl space, and the RH has dropped 21% already, from 95 to 74 (with the Compact Aire dehumidifier).
Durability of the product is unknown at this point, but the high quality makes me think it should last a fairly long time.
Could not ask for better than this. Installation was hard work, but that was to be expected. Product performed excellently and install actually went more smoothly than I expected.
This is three times heavier than anything I can find locally. I precut into sheets in the yard, I think dealing with the roll under the house would be quite hard. It's a bit stiff to get into the crawl space and unfold. As with another reviewer, I'm glad that day is behind me. I was sooo sore! It cuts like plastic with sizzors. The rocks and bits of broken concrete left from construction only put dents in this product, no holes. I am impressed with its strength.
Extremely tough, well made material. My son and I installed this in our crawl space after watching the helpful videos on this website. Shipping was very quick and the product seems very well made. For a permanent moisture barrier, this is worlds above anything I could find in local stores, and after seeing how well it is made, it's actually a very fair price for the quality of the product.
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™).
