a. 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.
ii. If the patio is not yet installed,
you MUST establish the desired
patio surface 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. 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
