How much to pour a concrete slab 12x24?

How do you tell if you have a monolithic pour on a concrete slab?
If there are no seams in it - it was not poured in sections, but as one continuous pour.
Can you pour concrete on concrete I had an addition added to my garage and the new section is over 3 inches lower than the original?
You should be able to pour an additional 3" over the new section. It wouldn't hurt to coat the existing with a bonding agent, after "keying" the surface by roughening it so that the new slab grips onto the old. First check whether these was a reason for the slab being laid at that level. Is it to do with the moisture barrier of the new slab? Slabs that do not have moisture barriers are often set below those that do to reduce the chance of moisture entering the dryer slab. If the slab level is a mistake then any contractor who poured it should be liable to pour a topping slab to bring it the correct height.
