What table base can support a 3 1/2' x 7' granite slab outdoors?


I have a 3 1/2' x 7' bullnosed granite slab that I want to use as an outdoor table. What can I do for a table base that will support the weight of the slab?

This is an open ended question. it really depends what look your trying to achieve. Assuming that your granite piece probably weighs close to a 1000 lbs, I would build a base out of cement blocks and have stone work installed on the outside perimeter.

Or do something like this: http://www.suvstone.com/b/GAO035-Sto...le%20Bench.jpg

A 1 inch thick X 12 inch x 12 inch piece of granite weighs between 14 and 15 lbs.

Well, if you look at this picture which is on a job I was working on just a couple weeks ago, the upper granite slab is 4" thick 18" deep and roughly 7' wide. It took all of 7 men to get that slab which was estimated to be around 750 lbs hoisted to it's current location in this picture.



You may be correct with your dimensions, but if Trici's slab is 3-1/2" thick by 7' long and the depth we still don't know but can assume it to be at least 2' to used as a table, I'm pretty confident that 1000 lbs is not out of the question.

"
i install granite everyday. 18" by 7' is probably only a few hundred pounds but you said it was 4" thick??? even so i highly doubt that is anywhere near 1000 lbs if 750 lbs
