Our crawl space was full of sharp edged gravel. The 550 felt was the perfect answer as a barrier between the 12 mil vinyl and the gravel. Easy to install and seam. im

It became almost like a cushion between the gravel and my knees. I would strongly recommend the use of this felt with any of the vinyl encapsulation product it made all the difference in protecting the vinyl.

Works incredibly well. I plan to tape up a friend for Halloween.

We doubled up the extra material in the areas that will experience high traffic areas. Easy to install and maneuver.

Once I understood what this was, I ordered and used 5 rolls. I covered my entire crawlspace floor with it prior to putting down the vapor barrier. It is strong and really is just what I was looking for.
