Doubling your slab

Hi A. Helmer
If your existing slab is in good shape, I'd butt your new slab up against it, putting an expansion joint in between. If its not in good shape, I'd break up the old one and do a complete pour for your new slab. My personal preference is not to pour over an existing slab as strange things are likely to happen if you do.
