Manufacturing-

GuardianLiner® is proudly made in the USA. While the industry is being flooded with low quality import tarp material, CrawlSpaceRepair.com is standing strong with our American manufacturing partners to offer our fellow citizens a properly manufactured crawl space vapor barrier. We make GuardianLiner® vapor barrier in the same ISO certified manufacturing facility since 2012. The manufacturing quality of our products is what matters most to us.

Tested-

Our GuardianLiner® crawl space vapor barrier is tested at the end of the manufacturing process for quality requirements to insure 100% bonding of the layers, uniform thickness and complete coverage of the reinforcement material. Once passed the first QC step is complete a sample is sent to a lab in Minnesota for purity testing to ensure the vapor barrier is free from  odors and off gassing. Once the manufacturing run has passed all testing it is given a Tested Pure™ certificate and brought into our distribution channels.
