Crawl Space Repair - Old Crawlspace Liner

This homeowner had previously laid out a crawlspace liner, however, because of several factors this liner obviously was not doing the job. One of the main issues with these liners is the thickness of them, or rather thinness of them. Another issue that generally comes with putting in these liners is that they are not sealed correctly. If the liner does not cover the entire floor and is not properly sealed then moisture can still get into the crawlspace and cause issues.
