    TOUGH STUFF!!!!
  

*by M***E on Reviewed in the United States on January 6, 2022*

This stuff feels like bicycle tube tires.  Which may not be descriptive to all people, but lets just say it is nice and rubbery and I wouldn't expect it to tear/puncture easily.  No doubt it will tear and puncture with the proper force (we cut excess with ease), but compared to cheap pond liner - this stuff is tough.  We bought some much cheaper (cheaper as in $$$) pond liner for a different purpose 6 months... 10 or 15 mil I think.  This 45 mil "firestone" stuff is way better (and physically heavier).  The cost difference is definitely there, but I didn't feel bad paying the extra $$$ once I experienced what this is vs the other stuff.  I doubt I will have another pond in the future, but if I do I will be buying this material vs cheap pond liner.

     This is a tough liner.  I've used these liners before in different sizes and I'm always pleased with how well they hold up over years of use.  Several of these rocks are pushing 200#'s plus.  I did use a Nonwoven Geotextile Underlayment with them but a great liner to create whatever you can envision!

    Easy to work with
  

*by D***A on Reviewed in the United States on December 23, 2021*

Never expected to do a liner change in December in New England.  Flexible & easy to work with. Purchased at a great price. Will always use rubber- that PVC/or whatever is CRAP.
