We bought a roll (i think it was 1000 feet long) of miss printed billboard vinyl for use as weed block under water. Stitched rebar to it with zip ties for balast.... anyways other story
3 years being under water in full sun and now going on 10+ years on dry land without any issues... Not like the blue/orange tarps that would've shredded themselves in the wind by now. Using left over material tovoer wood piles and as a "temporary" permanent back wall on an out building (that one you can still clearly read kaufman's on)
It's been a long time since it was purchased... but i think after motor freight delivery it was under $1000 for 12,000sq ft
