Thats why you have to look for the "ground contact" rating. I can't
believe they sell pressure treated landscaping timbers that are not rated
for ground contact. Yet people buy em (pressure treated is pressure treated,
right?) thinking they are getting a bargain and they rot out in 5 years
(the timbers, not the people).
The local big box store had timbers on sale (rated for ground contact in the
ad). WHen I got to the store I could not find a single sale timber that had
the ground contact rating printed on it. YEt the more expensive timber (next
pile over) had the ground contact rating on every timber. I bypassed the
sale.
This goes both for the old arsenixc ones and the AC-3 ones.
