How to Tie a Covered Patio to the Foundation

Lay out the desired area for the covered patio and mark each corner with chalk or paint; if the patio adjoins the house, you'll only need to mark the two corners on the opposite side of the patio. As a general rule, add a mark for an additional column every 10 feet between the two outside marks.

Place a column centered on each mark, then insert a marker through each of the bolt holes in the mounting plate to mark the concrete, ensuring proper placement for each bolt. Set the column aside when finished.

Drill 1/4-inch pilot holes through each mark in the concrete using a masonry bit; make the holes as deep as the length of the bolts. This makes it easier to install the bolts later.

Position the column back on the column marks so the holes on the attached mounting plate line up with the holes in the concrete.

Insert the masonry bolts through the holes and tighten; after tightening one bolt, add the bolt that is across it diagonally to ensure even tightening of the mounting plate.

Check the top of the column pole to make sure it is level. Insert and tighten smaller bolts as necessary to level the column. These types of mounts use small bolts that compress against the plate to level it, eliminating the need for shims.

Slide the decorative aluminum column tube over the aluminum pipe, if desired. From here, attach a pergola roof for minimal shade or a complete roof for full protection.
