Excavate the Subgrade

there's gonna be a lot of dirt coming out of here all right guys so this i realized was gonna be a great project and mental note let's remind danny not to create nicknames for the guys he's terrible at it i don't know what boulder busters means um but this is actually a this project actually is a really great project to use as an example of how we install the papers and i thought well what a great opportunity for us to start to master the basics so we're going to install this paver sidewalk where you've seen sam talking right from the beginning all the way up to the house and show you what we do step by step now the first step is the excavating and as you can see blaine is using the flat nose of the bucket and he's not over digging this is kind of an important thing that i want to bring up if he does over dig it's not the end of the world but you can't just put that dirt back in and and hit it and hope nobody sees it because what'll happen is somebody will see it like in three years so let's say you over dig by just six inches right you just one scoop a little too deep put the dirt in pack it it's not gonna bridge you gotta put that dirt back in it and you got to pack it with a actual packer and when i mean you know hit it a lot of guys will hit it with an excavator bucket or something like that thinking that's good enough and it's good enough at the moment but what'll happen is over a course of a few years if you've had six inches you dug too deep and you pack it you'll you're not getting that whole six inches packed and you're gonna have a little bit of settlement down the road so it's important to do it right sorry that took me so long to explain [Music] organic material let's address this you can't have any organic material below a structure a sidewalk so even though sam laid out the string line which will help him cut ler understand how far down he has to cut if he hits the bottom of that cut right where the asv is right now and he's still finding black dirt he's still got to go deeper it's all got to be removed we can't leave any organic material behind and let's say that let's paint another scenario let's say you dig down and it's just nasty all the way down as far as you go it's nasty well there is a technique to bridge if you can't dig all of the bad material out and bring all good material in we call it bridging and that's where we kind of dig down to a certain depth and we put the material back in place but then we layer grid into the base and…
