The main goal in this method is
to discretely isolate the pergola
posts from the patio area. This
allows the patio to move up

and down over the seasons
while the pergola posts stay
plumb and level. To do this
properly, we recommend that
the footing height be at least
one paver thickness below the
finished grade of the patio.
i.
If there is an existing patio,
you can simply remove
blocks as necessary to form
and pour footings to the
height just below the existing
patio surface. Use a concrete
saw to cut the paver blocks
to fit around the post once
the forms are removed.

If the patio is not yet
installed, you MUST establish

height prior to
forming and
pouring your
footings. The end
goal is that the
patio block will
fit neatly around
the post without
fitting under it.
This allows the
patio to freely
move up and
down without
squeezing or
crushing parts
of the pergola
post. NOTE: It
is common that
the patio will
have some slope.
Installation Guide
This is no problem. Simply
set the top of your forms
to follow the desired slope.
The roof of the pergola
can still be installed level.
b.
Determine post locations
and layout with strings
and tape measures.
c.
Minimum footing size =
12" round or 10" square.
d.
Dig footings to frost line,
making sure to remove
excess loose dirt from the
bottom of the hole. In regions
without a seasonal freeze
thaw we recommend a
minimum 36" footing depth.
e.
If the desired top of the
footing needs to be above
the ground around it, build,
stake and level forms over
your holes. Ensure your forms
are installed square to patio
or structure. It is often helpful
to set string lines to double
check the locations as well as
desired height of the footings.
f.
Fill holes with concrete to top
of forms and trowel smooth
g.
Once cured, attach post
mounts to footings using 3/8"
dia. hot dipped galvanized
wedge or screw type anchors,
minimum 2" embedment.
Use composite shims
as necessary to plumb
