How To Pour Concrete That Will NEVER Crack | THE HANDYMAN |

here's an update on the sidewalk the grass it it goes through like a shock face so it goes away starts browning up and then actually it's just starting to come back still not done with this the whole front yard is going to get landscaped people were very concerned about how that was gonna finish out don't worry about that we'll get to there here is the rebar now it really wasn't easy to find someone that would dowel into the foundation and put rebar in it's not very common around here it's not an earthquake zone this here is just sitting here right now and this will get pulled up once they start pouring this is probably the best you're gonna get now this is Road base and it just compacts real easy while you watch this sidewalk being poured I wanted to share with you some basic knowledge of concrete things to get you started to do your own project or things that will help you if you're gonna hire out this work to a contractor the first thing you need to know is how many people are you gonna need I suggest to one to work the wheelbarrow and one to move the concrete around and Street it out when you truck driver shows up and there's just one guy standing there he's gonna ask how many people do you have and if you just say one you'll probably tell you okay you've got 10 minutes per yard when this poor they had about two and a half yards of concrete so they got 25 minutes to work with the truck driver that is to move the concrete to the forms and get its treated out now if you're doing this by yourself you're gonna have to be moving fast you're going to take one or two wheelbarrow loads set it right that time and then you're gonna shovel it out and Street it and go back and get some more with this small of a poor one guy probably could have gotten it done notice that the the house side doesn't have a form it goes straight up to the foundation on the house side as you saw earlier there's rebar drilled into the foundation wall so that that will never fall once it's secured how do you know where your line is you snap a chalk line from the front to the back and when he was speeding it out there was an angle on one side of his 2x4 and he put that right up to that chalk line to level out the concrete [Music] this here was just a big float that he's going through now he's using a smaller float all the concrete has been put in place and now he's just finishing it this trial here I actually have this exact same trowel and then you're the next trial is going to use is circular on both ends that just reduces the lines that you'll get when you're putting that fine finish on it this is an inch trial here this puts a like a bull nose on the corner of the concrete so that you don't get chips this is this is part three in the video series and in their first series people were wondering why is that concrete so weak that I was removing it was 3,000 psi concrete that is just how easy three and 3,000 psi concrete breaks this concrete is 4,000 psi concrete now what's the difference the difference between your compression strength and concrete is the ratio of cement to sand as your psi goes up the sand goes down and the concrete goes up aggregate usually remains about the same in this application we did use rebar around the perimeter the the side away from the house was a little bit thicker so I had kind of a thickened slab where that rebar was placed if you wanted to go a step further you could put mesh put mesh throughout this it would be pretty much overkill and if you wanted to go even further you could put fiberglass they have these bags of fiberglass that they just throw in and that puts little fibers in it something else that you're gonna want to pay attention to that has a direct relation to the strength is how wet it is now you're probably not going to do a slump test and if you asked the the guys to do a slump test for just a simple sidewalk like this you're gonna get a funny look but you want about a four to five inch slump that will give you the the right amount of the dryer the concrete the stronger it is the wetter the concrete the weaker it is but the easier it is to work with so when they showed up the owner one of the guys said hey do you like what you see when you're a professional and you do this all the time you just kind of know the slump and how the concrete's going to work and you yelled up two more gallons and they mixed in two more gallons to the two and a half yards and this is what you got so Brooke that is yeah man while this fall we want you have to get hard be here today what you're seeing here is a broom finish it's a specific broom I've done smaller pores by myself or where I mixed in a mixer and just used a broom that you would sweep your garage with it comes out all right but it's a specific broom just like this gives you the best broom finish now you'll notice that the form this is the day of the pour this has only been going on for 20-25 minutes they've already pulled the form off that step that's how fast this concrete setting up it's about 98 degrees or so today and you could pull that form it won't fall but it's still just slightly wet enough where you saw him how he finished up the face there right here you see just a little bit of honeycombing on that that step there you'll see in the next clip what that looks like when it's been finished okay well here it is all cured up it's been been a few days it came out good this is a dramatic improvement in fact at least five or six neighbors have stopped by and asked both me and the the concrete guy to do their house this entire neighborhood looked exactly like this looked in the first video sums falling towards the house that was falling away from the house it just totally jacked up no rebar no nothing that's just it's just not very common around here you can see that it sloped away from the house and we have a little bit of an uphill and there is just a perfect spot for my my decking step up here that I'll be working on soon I probably won't make a dedicated video on that the next video about this house will be getting this irrigation system figured out we got this one here that used to be connected to something I'm guessing maybe it used to be connected to this right there so that that's cool that hopefully that is that's easy this one here is going to be the one that sucks this is I believe the output maybe it's not the output because I just saw water coming out of the ground pulling out of the ground so maybe I'll get lucky but I got a feeling I won't get lucky and have to dig up quite a bit of this these two boxes here are clean outs for the new sewer line that went in underneath the deck and all the way out to the street here that's it that's how you'd pour it and have it not shift on you because there's rebar around the perimeter on both sides they won't displace and since there's rebar dialed into the house everywhere it's not gonna fall it says 4000 psi concrete definitely overkill for a driveway you would you'd have around 4,500 psi concrete so this is his way overkill and I really shopped around to find this contractor and I glad that I took my time because he is definitely someone our I think the last shot that I had when this was still wet was this side here and there was a little bit of honeycombing in it they once they pull the forms they go back and they finish that and they gave the side here broum finish on the side all the landscaping will go up to the sidewalk there's going to be a ton of rock a lot a lot more bushes will probably redesign the sprinkler system I don't even know if they're gonna have grass out here it doesn't make sense I think they're going zero escape with with just rocks and bushes that's it for this video please put your questions below if you guys have experience in concrete at your own house maybe you would want to put your own input to some of the questions and share your experiences let's put some valuable information that other people can use in the comments
