Really good product! I used it in my crawl space high traffic areas (dirt in my crawl space is strewn with sharp rocks). Also, placed it over drainage rock on the interior perimeter drain trenches, and around the graveled sump pit. Mainly for added protection against the sharp rocks cutting the 12 Mil vapor retarder. The semi-rigid mat was easily cut with a razor utility knife yet tough enough to resist tearing and puncture by the rocks. I used EISENSP Landscape Steaks to hold down the matting and keep it from moving around. Notably is an undimpled edge about 3” wide along one side of the mat. Also, I found the mat has a slight dull chemical odor to it. The odor is not pungent and hopefully will dissipate soon. I would use this matting again. 4 stars instead of 5 due to the odor..

You can get the same Dampro from the big orange store for less.

Get this stuff installed as soon as you can! It will make working on the crawl space a million times better. No more crawling in dirt and rocks..

Easy to layout and a joy to have under knees rather than the gravel that was originally there.

Take this with a grain of salt. I just hope someone can avoid the mistake I made. I couldn't actually fit this into my 2ft crawl space without cutting into pieces, because these are long stiff rolls. Ended up selling at a loss. Anyway, my impression having handled these first hand is this isn't a very impressive product. The plastic doesnt strike me as extremely high quality. Namely, the dimples crush or break too easily. Simply walking on these wrong may crush some dimples, which may result in them pooling moisture, and simply not doing the job they're designed for. Maybe thats not a big deal if your crawl space isnt a high traffic area, but something to consider. Shipping these is steep so if you need to save some $, I'd recommend shopping at your local big box store first. Best.
