I am using this on the floor of the crawl space. I haven't finished the job yet, but the material seems to be very durable and I believe it will be great on the floor. However, I spread it out and opened it up and it was upside down. I opened it in the crawl space so I have to flip it over. That is a little of a pain.

Encapsulated my crawl space with the 20 mil product and I am very pleased with the finished result. The 20 mil thickness is stiffer and a bit harder to work with than the thinner barrier but it has allowed me to use the space for storage as well as a Radon mitigation using a radon fan. I installed over Felt 550 to provide extra protection for the vapor barrier and ensure the ground gasses would be able to move to the pipe under the vapor barrier. The vapor barrier pulled against the crawl space floor when the fan was turned on. Radon levels reduced to <1.

 

Very easy to work with and they secure the plastic drape to the foundation walls better than any other product.

I have recently purchase a 12 mil crawlspace membrane, the foundation tape, the waterproof seam tape and the pins. I was very impress with the quality of the products, the crawlspace of my chalet is now clean and no more smelling or humidity. As an general contractor this is the kind of product we are looking for, I have decided to offer the product to my own customer, this is definitely way much better that the 6 mil polyethylene that the CNB suggest we install in crawlspace. The membrane is very resistant and will last for years to come. Thanks for an awesome price. André Allaire General Contractor Vita Project inc.

Very good product. For our purpose, it was the right choice. The area we covered does not get a lot of use, yet the 12 mil HSU looks like it will last a long time. The customer service was excellent. We called before we ordered any of the products and talked to one of your reps who answered our questions without giving us the sales pitch to get an order. We appreciated that because it gave us time to go back and look at the project and review what we intended to do. The website was very helpful and gives the DIYer a place to start. Delivery was quick and everything we ordered came on time, with no damage.
