How to Install Deck Support Posts?

Published in Deck Construction 4 mins read

Installing deck support posts securely is crucial for the stability and safety of your deck structure. A common and robust method involves anchoring the support post base to a concrete footing using fasteners like sleeve anchors.

Overview of Deck Post Installation

Deck support posts are typically anchored to concrete footings that extend below the frost line. The process ensures the post remains stable and transfers the deck load effectively to the ground. While the entire installation involves cutting the post to height and connecting it to the deck beam, a critical first step is often securing the post base connector to the footing.

Anchoring the Post Base Connector to the Footing

The provided steps detail the process of anchoring a post base connector to a concrete footing. This connector provides a solid anchor point for the wooden post.

Required Tools and Materials

To complete the anchoring process as described, you will typically need:

  • Post base connector(s)
  • Sleeve anchors (as specified in the reference)
  • Heavy-duty hammer drill (as specified in the reference)
  • Appropriate concrete drill bit (sized for your sleeve anchors)
  • Pencil or marker
  • Measuring tape
  • Wrench or socket set for tightening anchors

Step-by-Step Anchoring Process

Follow these steps to securely anchor the post base connector to your concrete footing, based on the referenced method:

  1. Position and Mark: Place the post base connector on the concrete footing at the designated location. As the reference notes, mark the post's corner on the footing. Ensure the side of the future support post's side should be flush with the outside of the beam or doubled header above for proper alignment.
  2. Outline the Base: Once positioned correctly, draw the outline of the post base connector onto the concrete footing using your marker or pencil. This outline serves as a guide for placement.
  3. Mark Anchor Hole Locations: Place the post base back within your drawn outline. Using the pre-drilled holes in the post base connector as a template, mark for the hole locations directly onto the concrete footing. These marks indicate where you will drill for the anchors.
  4. Drill the Holes: Using a heavy-duty hammer drill equipped with the correct size concrete drill bit, carefully drill the hole at each marked location on the footing. Ensure you drill to the depth recommended for your specific sleeve anchors. Remove dust and debris from the drilled holes.
  5. Insert the Anchors: Position the post base connector over the drilled holes, aligning the holes in the base with the holes in the concrete. Insert the sleeve anchors through the base and into the concrete holes. Tap the anchor in using a hammer until it is fully seated.
  6. Tighten the Bolts: With the sleeve anchors in place, use a wrench or socket set to tighten the bolt on each anchor. Tightening expands the sleeve within the concrete, creating a strong, secure connection that fastens the post base connector to the footing.

After the post base connector is firmly anchored to the footing, the wooden support post can be installed into the connector according to the manufacturer's instructions, typically using approved fasteners like nails or structural screws.

Practical Considerations

  • Always consult local building codes for specific requirements regarding footing size, depth, and anchoring methods appropriate for your region and project.
  • Properly sized anchors and drill bits are crucial for a secure connection.
  • Ensure the concrete footing has had adequate time to cure before drilling and installing anchors.
