ALL blue tarps are garbage, and have been since the early 1980's at least.. Where have you been?

They're meant for TEMPORARY, OCCASIONAL use. If you want a better tarp go with the silver or green ones. Even those aren't meant for permanent installations. No tarp is. Brown canvas tarps last the longest but even those aren't forever.

I've got a couple of heavy duty brown plastic tarps that are at least
twice as thick as any other tarp I've ever had. Don't know where they
came from...other than that my dad bought them for me years ago.

A group I volunteer with has some large (like 20' x 20') silver tarps
that we've used to cover equipment during overnight torrential
downpours. We've had them for years, are not very nice to them, and
they are still waterproof.
