Crawl Space Repair - Old Crawlspace Liner

We see this type of crawlspace liner/vapor barrier very often, and more than likely you probably something similar as well! While these sometimes help to keep the your pants clean when you're under a home, that is pretty much the extent of what they do. There are two main reasons why these liners aren't particularly effective; 1) they are too thin, which makes them easy to rip and tear, and 2) when installed, these liners are usually not sealed properly, if at all.
