The main goal in this method is
to isolate the pergola posts from
the patio area without looking like
it. This allows the patio to move
up and down over the seasons
while the pergola posts stay rock
solid. To do this properly you
need to make sure you know
the finished grade of the patio.

If there is an existing patio, you
can simply remove blocks as
necessary to form and pour
footings to the height of the
existing patio surface. Use a
concrete saw to cut the paver
blocks to fit around the column
once the forms are removed.

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 column
base without fitting under it.
This allows the patio to freely
move up and down without
squeezing or crushing parts of
the pergola column.
