Pouring Concrete Slap over Concrete piers
	
	
		I drew a fairly detailed drawing of the slab that I wanted, with the piers (flagpole support piers, with pipes down to put poles into) shown so they could do it all in one pour.  Well, I guess our general contractor cannot read the drawings because all I got were the piers with the metal in them.  My question is... can I pour a 4: slab over the top of these piers that will not crack.  I think I know the answer (NO) but I would like to get some opinions.  They are about 9' apart, in a triangle shape.  I need to do this to put the "memorial" bricks that people bought to pay for this screwed up mess.  Any help will be appreciated.
