That number could increase to 40 to 75 years if you install the treated 4×4 in a cement ring rather than the soil. There are a few factors that influence how long the 4×4 can last in the ground.
What do you backfill a post hole with?
The trick is to use medium-size drainage gravel instead of pea gravel. The individual rocks in drainage gravel wedge against one another to mimic concrete. Backfilling with soil is usually only appropriate for a post-and-rail fence that isn’t heavy and doesn’t create a windbreak.
What do you put under fence posts?
Setting Fence Posts in Gravel Gravel is best for fencing in heavier (more clayey) soils, and won’t work well if you have loose, sandy soil.
