Heavy duty, went down easy, great product! I will use it in my own home.

Just finished encapsulating my previously damp, musty crawl space. This vapour barrier worked great. I was really torn initially between the 20 mil liner and this, 12 mil liner. I was concerned on the durability as I have a very rough, poured concrete crawl space floor, even though I don't use the space for storage. I wanted to avoid a high repair cost so I opted for this liner as it was on sale. I couldn't have been happier. It's very heavy duty and a extremely sharp razor knife is needed to be able to cut it. The space I encapsulated was roughly 1200sqft and around 18" in the tallest spot. Laying on my stomach and moving this liner around wasn't the easiest thing I've done but the liner performed as expected. Would highly recommend this product.

Product was delivered as expected (3 days from purchase). Product was thick and fiber reinforced. I used two rolls of this product to complete the vapor barrier for an 1500 sq foot crawspace. It cost a little over $500. The cheapest install in my area was about $3500 for equivelant quality. It took about 20 hrs between 2 people. While it was hard work, it was well worth the savings and the product looks very good.

We had two reasons to use these materials in our crawl space: 1. Our radon level was measuring 14.4 pc/liter in our basement 2. Our house had a little musty odor when we would return from out of town trips. Our crawl space was dirt covered with pea gravel. After viewing the videos on your website I was convinced that I could resolve the above problems mentioned myself using your materials. I must say that with your information and materials we have reduced our radon radiation down to a safe level of 2.7 pc/liter and the musty odor in our home is gone. The total work took about 40 man hours but I saved approximately $4300 as a do-it-yourself project. Your materials were easy to work with and performed as you advertised. Thank you!

GuardianLiner is a great product! I am so happy with this crawl space barrier. It is easy to install and is tough material. It is well worth the cost.
