When I first reached that place where you're supposed to work your way up with Concrete Shot I didn't even know the weapon could do that kind of thing Instead I found out that you can just call Rush Coil to jump up. If you time it right, meaning you have to call Rush the second you enter the screen, you can do it and it's become standard procedure for me. I know from other forums that I'm not the only one who figured that out and I also read that some people who tried it didn't have luck, but I can assure you it works. If you want the "Conservationist" Achievement it's probably a must, but I'm not sure.

Here's a video: YouTube - Going through lazers without concrete shot
But the guy in the video does it a little different, more complicated. The first jump he makes goes to the left ladder, which only leads to the Engery Tank, but you can reach the right (middle) ladder as well. Not the one to the far right of course. But if you climb up the middle ladder you can jump to the right side and go on.
