How to Anchor a Pergola to the Ground

A pergola is an outdoor shade structure typically composed of four posts and a series of rafters. Grow vines over a pergola, or add lattice to its top to make a shady summertime picnic area. A pergola's structural integrity rests on its posts and how well they are anchored to the ground. They can be set in the ground with concrete or anchored at ground level with heavy steel brackets embedded in concrete footing.


Anchoring Posts in the Ground

1.Dig holes in the locations for the pergola's posts, making each hole at least 12 inches in diameter and the depth of one-third the height of one post. If, for example, each post is 12 feet tall, then make each hole 4 feet deep. In that example, the pergola will be about 8 feet tall. Make the holes deeper if doing so is necessary to go past the average depth of frost in your area.

2.Prepare a batch of concrete mix by following its package's directions. The preparation results in wet concrete.

3.Pour a 4- to 6-inch-deep layer of the wet concrete into the bottom of one post hole. Stand one post in the hole, and add a 12-inch-deep layer of wet concrete to the hole. Align the four sides of the post with the rectangular shape of the pergola, and use a 4-foot level to check whether or not the post is perfectly vertical, or plumb. Adjust the post as necessary to make it perfectly plumb. Fill the remainder of the post hole with wet concrete, and check again to confirm that the post is square and plumb. Repeat the process to anchor the remaining posts in their holes with wet concrete.


Anchoring Posts to Concrete Footing

1.Dig holes in the locations for the pergola's posts. Make each hole at least 8 inches in diameter. Make each hole's depth 6 inches below the frost line in your area.

2.Slide a concrete tube form to the bottom of one hole. Cut off the tube form 6 inches above ground level by using a utility knife. Fill the space between the hole's concrete tube form and the soil with gravel.

3.Prepare a batch of concrete mix by following the directions on the mix's package. The preparation will result in wet concrete.

4.Fill the concrete tube form all the way to its top with wet concrete. Push one galvanized post anchor into the wet concrete, and ensure it is square with the pergola's shape and is level, both vertically and horizontally. Most post anchors have an upper and lower portion with a horizontal plate in the middle on which a post will rest. This plate should be even with the top of the wet concrete.

5.Allow the concrete to dry. Set one post on top of the post anchor's horizontal plate in the dried concrete. Have another person hold the post plumb and square while you drill through the holes in the post anchor to make pilot holes for galvanized bolts in the bottom of the post.

6.Pass the bolts through the post, and tighten them to the anchor with a wrench or socket. Ensure that the post is plumb as the bolts are tightened. Repeat the process with the remaining posts.
