The product is supposed to be "high strength" but was damaged during the shipping process when wrapped in a protective layer. The damage was done to several layers of the Silverback Vapor barrier and I would not trust it under much stress or wear. Was told to patch it with the seam tape that I purchased for the job. If I were to do this again I would have purchased local. I thought I was getting a superior product and I have tarps that I have purchased that seem more durable than this.

RESPONSE FROM CRAWLSPACEREPAIR.COM- Thanks for the review. When a product is damage in the shipping process we replace it. High Strength does not me indestructible.

Bought this home as a possible retirement down sizer. I ended up saving the frame and started over. The crawlspace was a nightmare. We ended up adding gravel a new sump and crock to replace the wooden box. I purchased all my vapor barrier supplies from crawlspacerepair.com and couldn’t be more satisfied.

I have over 45 years of construction experience, but this was my first crawlspace project and if take your time the install wasn’t that difficult. Make sure you watch the videos.

 

Easy to work with. Feels even better over 42 liner. Cleans up well.

opted for the 12 mil guardian liner due to cost and it was on sale. was impressed with the thickness-yet very easy to cut. slightly difficult to work with in my tight crawlspace when spreading out and working out wrinkles. since I will not be entering crawlspace except to do maintenance--felt the thinner product was ok. In hindsight, if the area was higher traffic-would opt for the 20mil..after finishing the project, noticed several areas where small sharp objects were making indentations--not coming through..but since I wont be going in there--not an issue...overall--apples to oranges compared to the ancient plastic in there before.

Some parts of my job was over sand and some areas were hardend clay. There was also an area of old block footing with some jagged edges, so I decided to use strips of 12 mill on top of the blocks for a second layer of defence. Over all I've been crawling repedly over the plastic fixing various neglected issues due to lack of motivation to crawl around on dirt with spiders and centapieds. While the sand areas are easier on the knees, even the hard jagged edges of the clay have proven to be problem free from puncture. The house now smells better and the humidity is in check!!!
