I purchased the 20 Mil liner for my new construction crawl space and had it installed and then sealed to the walls by a reputable spray foam company. They and I are were impressed with the product. The crawl space has extremely low humidity since installation. The liner seems very durable. I am happy with the choice.

Was exactly what it was advertised to do. Excellent product to work with. Also your videos were very informative and easy to follow. Would recommend this company to anyone that wants to in capsulate there crawl space.

 

Great material for your crawl space. Keep in mind that the thicker you go with the material the harder it will be to install around and in the corners. I went with the 12mil.

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.

Great product; it is expensive, but you do get what you pay for. Don't take a chance on paying for thinner material from the big box. Once you rip a few holes in thinner material, you've just wasted your time and your money
