Hello. This is another question that came up as I plan for my crawlspace-to-basement conversion project (details in this post: http://www.houserepairtalk.com/f39/new-amateur-project-11441/)
The basement slab I'll need to place will be approx 600 SqFt. My understanding is that the pros charge roughly $5/SqFt which would cost me around $3k for the slab. I'd really like to avoid that expense if I could. :hide:
Since the slab will need to have control joints cut every 10' anyway, I'm considering doing this myself in 10'x10' sections using my (admittedly small) 3.5 CuFt mixer. I'm thinking that when each section cures, I can remove the forms and pour the next section right against it. The cured sections would help in screeding new sections.
I'd probably embed a rebar grid to prevent any uneven vertical movement over time since separately poured slab sections would not have the mechanical interlocking properties that a crack along a control joint would have.
A 10'x10'x3.5" slab section would be 30 CuFt. That would translate to about 10 batches in my mixer. I think I can do that and get the slab screeded before it starts to set.
So ... am I really off the mark on this? Thanks in advance for any replies.
