In-Ground Mounted Post Installation Instructions
Installing the In-Ground Post Directly into Concrete
Dig the hole for the concrete footing and prepare the concrete. You
will need approximately 4-1/2 cubic feet. The top surface of the
footing should be about 12” by 18” and extend 36” into the ground.
See the illustration for the relative position of the rectangular footing
to the post and mailbox. The bottom of the hole for the concrete
footing should be filled with about 6” of gravel to promote drainage
under the post. The top of the footing should be sloped for water
runoff.
The concrete must be below the frost line. Otherwise the post will
move when the ground freezes. Be careful not to puncture water,
sewer, or gas lines when digging holes for footing.
Set the post in the hole and fill the hole with the prepared concrete
mix. Prod the mix with a stick while filling to reduce any air pockets.
If you want to conceal the concrete, pour it to within a few inches of
the top of the hole and cover with soil after the concrete has set. Use
a carpenter’s level on the sides of the post to ensure that the post is
aligned vertically. Periodically check the vertical alignment of the
post as the concrete is curing.
