Can I install pressure treated decking over existing concrete slab? I have an old concrete slab where my stairs for my deck sit on top of. The problem is that the slab with the stairs on it is only about 18" wide and there is a sidewalk that runs perpendicular to it. Any ideas on how to make this work?
I thought about running 4x4 posts along the perimeter of the slab and then putting down p.t. decking on that. If this doesn't work, could I use composite shims under the decking to give the area some drainage? I can't raise it too high because then it would be an awkward step up onto my deck stairs.
