Hi, I'm Tim Gipson. I'm going to talk to you about how thick to make a concrete slab. Now, when you're looking at pouring concrete and how thick to make it, really gotta look at your application and how much force is going to be on that. You know, for typical, for patio applications such as this, whether it's a concrete or an aggregate patio such as this, typically these are going to be about four inches thick in these areas. Now, if you get into areas like your driveways, then, those could be even thicker. What you want to do, depending on your application, is you can go to your local codes department and you can talk to them, or you can, and they can give you some guidelines as far as the application and what you're pouring your concrete for, they can give you some guidelines on how thick that needs to be. Now, some other things that come into consideration when you look at how thick your slab needs to be, really is on the formulation of the concrete itself. A typical standard concrete comes with a mix such as this. You have to prepare it over a crushed rock base, and then have actually welded wire that is set in the concrete to give it it's strength. However, some of the new concrete actually has fiber added into the concrete, which takes the place of that wire mesh, and it actually makes it....it's basically like a lot of cotton fiber, or different type of fibrous material that mixed within the concrete, so it makes it much stronger. Which means that you can go a little bit thinner than what you normally have to do because you have a greater strength of that concrete. Typically, where you can buy your concrete, you can get a lot of information, talking to those folks where you can buy your concrete from by the truckload. 'Cause when you get into large applications like this, typically what you're going to do is you're going to buy that by the yard. You know, in most mixes that you find like this in concrete, you know, most of your applications are going to be a couple two or three yards of concrete, anyway, which in most cases is going to be your minimum. So that's some things to take into consideration, is the formulation of your concrete and then the type of application it's going to be in. And again, you can either check with your local concrete suppliers or your codes department to find out exact thicknesses for those applications. I'm Tim Gipson with some information on the thickness of concrete.
