Ok I have done several paver projects now but I know that I have more to learn. When you are establishing the sub base grade, do you guys use strings or lasers? And after the gravel base is in, how do you go about getting all the little high and low spots out as you compact without setting up strings everywhere? I feel like I have to set up a grid in about 3' sections to get everthing level. Then I try to compact and the strings get all screwed up. Is there a better and more efficient way?
