Forming Radius Corners On a Curved Sidewalk - Complete Sidewalk Setup and Pour

this video I'm going to show you how I poured the sidewalk and I'll show you how I set up those curves there on the sidewalk and how to form those up so keep watching so you can see here I'm coming off my patio and then I turn but I don't want these sharp corners so what I'm going to do on that inside corner down this outside corner when I start forming those up I'll show you how I do that so people have a tendency to cut corners so if I'm walking down the sidewalk and I want to go that way I'm going to cut that corner so I want to put a nice big radius right there so I have my initial layout ready to go I'm gonna get my form board set I need to figure out the height of my concrete that's gonna be between the house and the barn and that's gonna determine the height that my sidewalk is but I want to do the sidewalk first before I pour that section because I don't want the only way to get the truck here is through this opening right here so I don't want to have the truck over finish concrete when I'm trying to for these sidewalks so the sidewalks have to be first but I have to set that height first and then I can set my sidewalk height so depending on your situation you may want the length of your sidewalk nice there clam but you'd probably want to just tilt it a little bit so everything drains off one side or the other you're gonna have to look at you know the the slope of your yard how much rain you get one spot you have now all that he should take into consideration when trying to determine the slope of your sidewalk I'm gonna use what's called a hula hoe or maybe a scuffle hole to get any vegetation here inside where my where my sidewalks going to go just gonna work it up this is pretty handy tool it actually works pretty good I'll leave a link in the description if you want to check it out so I found the height of my slab that I want over there and now I've worked my way this way so I'm just gonna start putting my form boards up when I get to the radius I'll show you how I do that one am i more poor to 75 inches of Foundation and wherever I'm going to splice to form boards together like to use a 2x4 there and split the difference that way I can screw both for boards in the same state and kind of splice them together I normally like to get the top of the steak below the forum board so when you're screening along it doesn't catch on these and it just makes it nice and smooth this one's going in real hard so I'll just come back later and cut that one off - always remember screw your steaks from the outside otherwise you're gonna have a hard time getting all your form boards off with your screw from the inside you get the point your steak and everything up when you pull your form boards so if you put your screw from the outside then you can knock your steak loose pull it out and then take your work you so that first forum board I put up I kept the same slope coming from where the others labs gonna be and then once I got past that point where the water can start running that way now I leveled out this forum board so this forum bird will be level I'll slope the slide sidewalk that way so I want to make sure that this forum board is coming off with that patio square so I'm gonna use what's called a 3 4 5 triangle to do that so I have 3 foot from this corner to the edge of my forum board here if I measure out 4 foot and make a mark here then this hypotenuse of this right angle will be 5 feet so if I pull that in right there but I know where my board being squared you so you can see I've got plenty of height here but I want to get all this vegetation out of here so I'm gonna scrape all this vegetation I'll make sure I'm got all the loose soil out and I'm down to a good hard undisturbed soil and then I could put some sand on top of it and pack it down you so to make this radius here what I'm using is I get this cardboard like paneling it's a beef board but it's made out of like the masonite so it's about 3/16 of an inch thick and I ripped it down to about three and a half four inches where I made that that large rabbit there so that kind of sets flush I'm just gonna bend it around to what looks good so there's my radius I'm cut it off and then I'm gonna try and keep that same radius then for my other corners you so I'm going to back fill this with dirt here and I might even have to put a stake behind it at this point - just to keep it because it is gonna be kind of flimsy because it's so thin but that will end up being the form for that for the radius you so I made this depth gauge here this is a two by four which is three and a half inches thick and put a couple of cleats on each end to ride on my forms so I can just straight along and get my sand down to a depth of three and a half inches once I'm at three and a half inches then check it again and this time we want to have like quarter inch to a half an inch under my screen still smidge high I'm figuring the slab for four inches thick so anywhere between three and three quarters and four inches would be ideal you're going deeper than four when you figure it for four you might end up short it adds up quickly if your whole slab is more important cheese thick so this type of depth-gauge works good for a narrow slab like a sidewalk well you can also do is make a board that right on top of your forms and put some 2x4 teeth hanging down four inches so I've built that type of 2x4 rake in some of my other videos on concrete work so there's gonna be a card up here that you can link to I also put it in the description too so this is pretty good now now just to keep it going all the way around so what I did was they broke down this poor in two sections so I could figure the square footage of them so that little section down there was 22.75 square feet and then this was eighty two and a quarter over there along the pole barn is 112 and then this bigger slab right here where in Neyland is nine and a half by 12 so that's 114 so now if we add all those up equals 331 divide that by 81 for 4.08 4.0 8 cubic yards so you take your square footage divided by 81 for a four inch that slab will give you your cubic yards of concrete you need so I will probably order four and a quarter so originally I was just gonna pour this sidewalk and that sidewalk there but um now that I'm I was gonna I was gonna put a form board right through here but I wanted to get this section on here poured too and I had to steal a bunch of sand from there to fill in here for the sidewalk so think I'm gonna adjust my plans and I'm gonna pour this whole thing all at once now so it's pretty much ready the two sidewalks are ready anyways I think I'm gonna put some mesh in there and it should be good I want to backfill the rest of these form boards right here and this one see it rained about two inches last night and this kind of swelled up a little bit so it's drying out good and it's it's hardening back up but I did have a little bit of a crack there but I think it'll be fine but when it's dry I want to want to backfill it nice and tight you we use wheelbarrows to haul the concrete down the sidewalk which actually worked out pretty good and it's pretty quick to do it that way as long as you have two people at least dedicated just on the wheelbarrows and it was a sunny breezy day so that concrete was gonna drive pretty fast so it's best to get the bowl float on it right away and get it smooth and maybe even get the edges done at least one time while it's still pretty wet you I think this clip here is a perfect example of why you need a bow flow when you're doing this kind of work as you can see it was pretty rough when we started and just going over it with the bow float helps to get it nice and smooth I didn't have footage of the rest of the finishing but I did actually get out there on knee boards and I finished that portion of the slab by hand here's the finished sidewalk so I think it turned out pretty good hopefully this brought you some value for did I appreciate if you subscribe and hit the like button thanks
