Default Re: Confused on footings???

badger,
That is good information. I would like to see pictures of the footing and foundation. Did you pour the footings yourself? (wheelbarrow and concrete) or did you have a cement truck pour the footings? What are the specs? How wide did you make the footings and how deep? Did you put anything in the footings rebar or wire mesh?

thanks,
fb66

Fullback66,

I dug down well over 30" deep by 12 inches wide (check the frost line in your area). I then poured a 6 inch footer min - maybe 8 in some spots in order to get it level. Took about 16 bags of concrete ~3 hours with 2 helpers. I put in two pieces of rebar on each footer run. After the pour set, I just dry stacked and back filled. So about 4 course are underground and the 4 coures (which you see in all the pictures) are above ground. I did tie rebar from the footers up into the some of the cores. I don't think this is going anywhere. My nieghbors really think I'm building a bomb shelter.

I could have called a concrete truck but wasn't sure when I could pour due to work and the cold weather coming in. This method (80 lb bags) gave me more flexiblity. I'm having trouble reducing my pic size but I'll try to post later. The one pic I could upload is the "hole" for the footer.

Thanks
Dick

The picture looks fine. How did you get the founadtion level so when you start stacking it would be level on top? Does footing self level? Because if the footing is not level and you start stacking the top layer may not be level.

-Do you morter the bottom row to get the blocks even before you stack the rest?

Did you have rebar sticking up from the footing? You stack your blocks over the rebar so it will be all one piece? If that made any sense?

When I build mine it is not going anywhere. Sorry for so many questions.

Do you have more pictures?

FB66,

"How did you get the founadtion level so when you start stacking it would be level on top? Does footing self level? Because if the footing is not level and you start stacking the top layer may not be level."

I tried to get the trench as level as I could. I built and leveled a 2x4 grid that I put over the trench. I leveled this to my patio/where I wanted the walls to be. I then built a very long screed to the right depth I needed. I just poured in the concrete and moved the screed along the top which transfered the depth to the bottom.

"Do you morter the bottom row to get the blocks even before you stack the rest?"

I bought a bag of morter but I didn't need to use it! Not bragging (probably just lucky) but when I was done I'm probably only an 1/8 "off level" with my top course of blocks. This process worked MUCH better than I thought.

Did you have rebar sticking up from the footing? You stack your blocks over the rebar so it will be all one piece? If that made any sense?

Yes I put 1 piece in each corner. I wanted to put more but I wasn't sure where my blocks would end up. I did drill down in the footer a little and put extra rebar in. In total I have 10 pieces of rebar extending from the footer to the top. I'll then use these to tie into when I pour my pad on top.

When I build mine it is not going anywhere. Sorry for so many questions.


I agree, don't worry about the questions. I figured out how to adjust my picture size - hope they help.

Badger,
Your jig to even out the concrete footings is really cool. Nice job with only a 1/8" differance at the top. I suppose I could put a little moter between some bricks to even out if I were off. You really helped me out. Now keep taking pictures so we can see the process.

What kind of drain system do you have? Do you even need one? Pea Gravel on the bottom before concrete footings?


Looks good.

FB66,

Nothing under the footings. The one thing I heard from the forum is that you DON'T want crushed gravel under this type of footing.

I'm pretty much done for the year. I've stretched my wife's patience to the limit since I wasn't allowed to start the oven until next year. I got by with the foundation/walls on a technicallity.

I'll post/start a thread when I get going in the spring.

Good luck.
Dick

Default Re: Confused on footings???

I am also stuck with my footing situation. I am in california, and the ground does not freeze here, so that's not a real concern for me.

I want to build my oven on top of an existing patio which is composed of 2-3 inches of gravel, then 3-4 inches of concrete (with 3ft spaced rebar) and then a 1-inch thick clay brick.

My understanding is that 3-4 inch of concrete is borderline. But I'm not sure what to do. I am thinking I should remove the brick where the oven is, install anchors into the existing concrete, and build up another 3-4 inches of concrete footings. But, this will be above grade.

What will happen in 3-5 years time? My guess is that the patio will crack. And I think the weight of those 3-4 inches of extra concrete will make the problem worse. So maybe the best thing would just be to remove the bricks and lay the cinderblock directly on the concrete (I'll still anchor them to the patio).

The other option of course is to remove the concrete, and dig down to make a proper footing. But who wants to do that!?!? (Do I?)

My solutuion would be to rent a large gas-pwoered concrete saw. The push-behind kind that looks like a walking lawn mower with a water hose attached. You can cut outside the perimeter of where you want your foundations to be, and then cut up the inside into smaller blocks by cross-hatching back and forth. You'll only need it an hour or two, so really pretty cheap. You'll be surprised at how quickly you can remove the cut up concrete and dig a proper footing.
