How To Build a Pergola Over a Concrete Patio
A patio is always a delight, the ideal space to relax and socialize with the family and friends on those cool summer evenings. But when a pergola is added, then the once cement surface suddenly gets a more attractive look while getting a supplementary usefulness. A vine-covered pergola and one to which to attach side curtains is poised to become the epicenter of the family life. Here are the practical information on how to build a pergola over a concrete patio, as seen on Ronhazelton.com
After you decide on the dimensions of the pergola, mark two perpendicular lines from your home’s eaves to the patio to mark the desired elevation of the pergola. Cut three two-by-eight beams for the first roof layer that parallels the house. Notch them with a jigsaw to support four of six second layer beams–the other two will butt against the ends of the first layer’s beams.

Position the post brackets, marking their centers on the concrete with a hammer and a sharp instrument. Drill a hole in each mark, insert an expansion anchor through the bracket into the concrete, and tighten it with a ratchet. Then iInstall post supports in the brackets to raise the posts above concrete and moisture to prevent rotting. After raising the support posts, align and clamp notched end beams in the first layer to the posts at the correct elevation. These two end beams are parallel to the ledger installed on the side of the house.
After the end beams are up, cut six second-layer beams with a decorative curve on one end. They’ll be longer that the depth of the patio and run perpendicular to the house. Notch the bottom edges to interlock with the notches on the first layer’s beams. Notch the second-layer beams eight times for the eight beams in the final layer and then interlock them to the first layer.
Finally, cut eight beams with both ends curved for the third and final layer. Carve six shallower notches in the bottom edges to interlock with notches on the second layer. Fit them together and tap with a mallet to seat them.
