So I understand the premise that you make a boxed in area using stakes in and get a level line running between the stakes and measure down to grade to figure out the differences.. but then what? Every video stops at that point. So I get some dirt and fill in the area under the string to bring it up, or dig it down.. and then what about all the inside space where there isn't string, how do you level that? via /r/DIY https://ift.tt/2LPtWvS
