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?
Location of deck? city, state
Is concrete a slab on grade? A pier foundation?
I doubt that the flashing would help much or be worth the effort.
You might consider drilling a hole into the post at a 45 deg angle such
that the bottom of the drilled hole is about 3 or 4" above the
fit the hole with palstic tube & funnel so that your can flood /
saturate the post base with some sort of wood preservative
if you want to go "organic" use raw linseed oil...like the Vikings :)
do this dance when the wood is as dry as it gets ......no rain or
watering for a long time
Sorry about the lack of clarity, Bob. That ws writen in too much haste. My
location is south- central PA. The concrete is simply pured in a hole
around the wood. All that said I think that your comment suffices as does
the site that buffalobill posted. Thanks to both of you. Have a great
