Foundation for 4" x 4" Support Post
The Heritage Pergola can be installed on a concrete patio, concrete piers, or in 31"- 48" deep holes
(depends on local building codes) filled with concrete.
Installation method for 4" x 4" wood support post on concrete piers
1. Construction of Piers
Step 1. Using a post hole digging tool, dig a
hole 12" in diameter; approximately
31"- 48" deep. Fit a 12" sonatube
down into the hole for the concrete
pier.
Step 2. Dig a 16" x 16" x 3" deep square
pad for Pergola Base (F) platform.
*Limestone column base requires a
13” x 13” platform*
Step 3. Level the pier platforms using string
line, wood pegs and a level (as shown).
Mix the ready- mix concrete with water
in a wheelbarrow (follow
instructions on the bag).
You will need approximately two
80 lb. bags of ready mix concrete for
each pier. Then fill in pier and pad.
Smooth the surface with trowel /
float.
* Curing times vary; follow instructions
on the ready mix bag.
