Yes 4inches deep by 50" x 50 " this is the website http://www.extremehowto.com/xh/article.asp?article_id=60223#other

Looks like a very nice project - very doable. A google found this concrete calculator that I think will answer you question. http://www.concretenetwork.com/concrete/howmuch/calculator.htm


I see the referenced article recommends 6" thickness and fiberglass reinforced concrete. I would agree with the 6" thinkness - this would ensure the slab would handle the weight of the BBQ and last well. I have no experience with the fiberglass reinforced concrete - I would put in wire mesh myself. I imagine someone will come along and be able to speak to the fiberglass reinforced concrete.

You might want to consider readymix concrete rather than bags. Several sources now for self-tow setups suiteable for smaller projects. You would come out with a better and stronger concrete mix and less work.

for 13 - 140 bags of apron store conc mix ? ? ? f/g reinforc'd is ok but we'd use wire mesh 'cause its on hand,,, try polypropylene or polyesther fibers instead.

The area is only 50 inches by 50 inches and 6 inches deep
