About

30 Mil LLDPE

  • Regarding size: "It would come as one piece but it may be heat welded for the width/length as I believe the max roll width is 12ft. All items are custom cut - we do not have pre-cut stock pieces of this product."
  • Possibly use tar paper as another layer of protection on top.
