concrete slab


I live in Austin, TX, I want to pour a concrete slab under a tall deck. It is just for parking mower and lawn items. I will pour small sections at a time, finished product is 14' x 16'. Do I need rebar, how thick should the slab be, ratio, etc.

The subject of placing concrete for a slab has been discussed dozens of times on this forum in the past couple of years, I suggest you read the posts, they will tell you everything you ever wanted to know about concrete and a lot of stuff you didn't want to know. You will find a variety of opinions about the usefulness/need for rebar, no need to rehash the discussion here, its all in the post history. My only comment is that it is usually easier to set up the forms and place the whole pad rather than try to do it in pieces, since that creates cold joints, and adds to cost because you need to rent a mixer for several days.

Yep I was thinking the same thing. I would rather someone not answer at all then to come off like that. But he is right there is a lot of info out there the idea is how to find it.

Anyway. there will not be much weight on it so it doesnt need to be terribly thick, but I would pour at least 3" over a well compacted base. I would make the sections as large as possible to avoid cold joints as the other commented. rebar is optional on such a lightly used pad. I always go overkill and put it in. that way if it cracks, and it prolly will, the sections are still tied together via the rebar.

Daniel is one of the more knowledgeable and most helpful people on this forum. Just like many others here, he has given out this same information time and time again. So have I. So have many of us. Despite the fact that we are here because we enjoy being helpful, it does get a little old to keep repeating the same thing over and over when it is already well written out in many places on the forum.

I appreciate the desire to do no more than ask a question and be given the answer. I like that too. But the SEARCH feature is included on this forum to easily and quickly give you access to any and all desired information. Try it. It's not hard.
