My is 20 yrs old and the 4x4 supports are sunk directly in the concrete. Inspection does not reveal any obvious rot... yet. I was wondering if making a flashing near the concrete/ wood interface but high enough to allow air circ would be of any use at this late date. I also considered using the glycol-borax-boric acid mix as a preventative. There is a bit of a gap between the wood and concrete that should accept this if it's of sufficiently low viscocity. I know that in the long run I't's a lost cause but is this a worthy project?
