How far off are they? Walls are seldom exactly 90 deg. And Dricore does not have to be installed tight to the walls anyway. As long as the panels are tight together along the row your fine.
If for some reason you want it exact just set the panel againts one wall and measure how far off it is by setting the tape on the panel and mark a line on it and cut it off by that amount. But if you do it that way your going to have to cut everyone.
