How to Attach Deck Post Bases to Concrete Footers

The footings of your deck are exactly what they sound like – the feet of the deck. They’re the concrete foundations that support your deck. In order for posts to properly resist varying degrees of weight, posts must rest on and be anchored to concrete footings. It’s important to note that patios and pre-cast concrete piers do not qualify as proper footings for deck construction.

To anchor posts to concrete footings, you need to use a post base connector. Whether you’re using natural, decay-resistant or preservative-treated wood, it’s recommended that posts be elevated off the concrete by 1 inch to help prevent decay at the end of the post due to moisture.

Hold your drill plumb.

Use a drill with a hammer drill bit to install a concrete sleeve anchor into the center of the concrete footing.

Don't over tighten the bolt.

Install the Adjustable Post Base to the sleeve anchor and tighten the bolt to secure the attachment.

Place your foot behind the post when nailing.

Set the 6x6 Pressure Treated Post onto the post base and attach by nailing the side flanges to the support post.
