can it be bent to a 90 Degree angle what i am asking is i want to wrap a 12x12 block of aquablocks and seal the top so i have the block sealed on 5 sides leaving the one side openI used a liner from bend tarp and liner in Oregon. They also have RPE, check them out, a great company to work with. At the time I bought it was called ppl. It survives anything. Including sun exposure. Deer have walked on it, rocks have fallen on it, zero issues. Even drove my tractor on it when we using it to bucket in the pea gravel for my bog.
I did not put any cover over the liner.
I love the stuff. It also does not get as slick as epdm, easy to walk on in the pond.
