I recently poured one side of my wifes barn floor for office, feed room, wash stall, etc. Now I am forming the isle way to pour it. The question I have is:
Do I need to put some form of expansion joint up against the previously poured slab, and should I pin the two slabs together by drilling rebar into the existing slab?? I'm worried when the new slab contract/shrinks back I'm going to have a troublesome gap between the slabs which might create a problem in the area of the wash stall.
The barn is on a compacted subsoil, I have 4-5" of 57's down with plastic vapor barrier, wire mesh and rebar (will be driving tractor and skidloader down the isle). The stall side of the barn will remain unpoured. No heat in the floor.
I've read differing opinions on the web but none matching my exact project. So any help would be appreciated.
