Slim I always have beer !!!!!!!!!! Sloppy that is probably what I will have to do. I was afraid of cracking or breaking the pipe if I forced it to much. I was trying to get it all the way to the bottom of the trench on the end but may not be able to do that.
You will not break Logstor piping (this side shy of repeated runnningit over with a track loader). It is "normal" to hear the polyurethane foam inside the Logstor "pop" (sound) during the bend. This is okay (it is just the urethane on th e"stretched side" of the pipe expanding).
I suggest this: attach the ratchet strap 10 feet or so from where you actually want the Logstor to bend (i.e. where the 90° bend will be) and on the vertical piece sticking up out of the trench. In tennis shoes, walk
on the pipe to the corner where the pipe is to be bent. Lightly flex your knees in a jumping manner (not true jumping mind you) in order to persuade the Logstor to bend... use more than one person if need be. Have a helper ratchet the Logstor to appropriate tension (that will hold your bent shape. Don't step off the Logstor yet! Have proper backfill dumped along the horizontally-laid pipe in the ditch (need I say "don't bury yourself?!). Spread and gently compact the fill a foot or two over that horizontal section in the ditch (this is the "weight" that will hold the Logstor down in the trench in order to preserve your bend; the ratchet strap holds the other end). Have your helper hold the vertical Logstor sticking up out of the trench in a true vertical position while back fill is deposited on the bend itself and filled enough to hold it in place. Gently compact and add backfill until you are at finish grade. Hope that helps!
