I have an outdoor patio slab, concrete and partially sheltered. I need to
level out and waterproof a number of depressions in the concrete where 8"x8"
wooden posts are imbedded in the concrete. The depressions are about 1" deep
and 1 sqft wide.
Since the wood and the concrete have slightly different expansions, I would
need a material that is not completely brittle. I am trying to avoid water
infiltration around the post and potential for dry rot.
Epoxy, what kind? Dense urethane Foam? Cementitious patch with caulk around
