Thanks!
Did not know folks were putting the builds in the gallery... I have seen a lot of them in this forum, and there is another current Texas build thread in here at the moment...
From the video is there no rebar? Is that normal or ok with a floor that big?
Small or large a slab should not be without reinforcing steel......
is it on footings or a thickened edge?
Really thats interesting, does that pretty much the case for a patio as well? Sorry not trying to hijack the thread.
Yes, but it was not lack of reinforcements...
It is difficult to see in the video because of the black plastic but there is large diameter mesh in the interior, and the perimeter beams are quite thick, 24+ inches with rebar boxing. There are also beams across the middle, but it is just thicker concrete with the same mesh as the interior. No rebar in the interior beams. They pulled the mesh up as they went along so it would not be just at the bottom of the slab.
The concrete is 4000psi mix and I do not anticipate any problems with it with respect to reinforcing.
The mistake they made is something else and I will get to that soon when I have a chance to post the next round of updates and pictures.
I don't know what it did... All I know is I witnessed them making efforts to keep it up. There is a limit to how much you can do and still get the job done. Like you said though, if you want high confidence that the reinforcing steel is still in the center after the pour go with rebar on chairs and a pump truck. That would be awesome but for this residential project that is a level of engineering that does not justify it's cost. Part of the compromises I spoke of in the first post.
Will it crack? maybe, but that is a gamble you take with any concrete slab no matter what you do.
At the end of the day I am parking cars and a Dodge 2500 on this... not Cat D11s or 747s.
