More on my fence building subject. I live in Oregon, Lebanon, near Salem.
Rains all year. Lots and lots of rain. I'm using pressure treated ground
contact rated 4x4x8' posts. I plan on setting them 2 feet deep in concrete.
Would it be worthwhile to apply any additional waterproofing coating to the
posts before setting them in concrete? What kind of life expentancy can I
expect from these posts set in concrete? Assuming I take reasonable care to
taper the concrete, cap the top, and keep it painted. If they rot out in 5
years, I'll be stuck with rotted posts in concrete that will need to be dug
up, and I'll have several dozen big chunks of concrete that I won't know
what to do with.
