Frequently Asked Questions (FAQs)

1. What posts to use for decking?

For raised or elevated decks, it is recommended to use structural posts measuring 100 x 100 x 1200mm. These posts should be sunk into the ground, with at least half of their length buried, and then secured with concrete or concrete feet and dry cement.

2. Should I put deck posts on or in concrete?

It is advisable to attach deck posts to concrete footers above the ground. This helps prevent wooden posts from rotting. The footers should be set at least 6 inches below the frost line in your area to prevent movement during freezing temperatures.

3. How deep should support posts be for decking?

Dig holes that are 700mm deep in each corner marked for your decking. The holes should be 400mm wide at the bottom and 300mm wide at the top. The posts should be evenly spaced, with the center of each post no more than 1.8m apart in any direction.

4. Should I nail or screw deck posts?

It is generally better to use screws instead of nails when installing decking. Nails are more likely to pop out, especially if the deck frame is made of a softer material like pine. If nails are used, ensure they are galvanized or stainless steel.

5. Should I use 4x4 or 6x6 deck posts?

In most cases, using 6x6 deck posts is recommended, especially for decks that require heavy load-bearing. While 4x4 posts were used in the past, they may bow under pressure, even for decks only 3 feet off the ground.

6. Do you need rebar in deck post?

While plain concrete deck foundations without rebar are acceptable under minimum construction standards, adding reinforcing steel within footings is a relatively easy and inexpensive practice that can enhance overall performance.

7. Are 4x4 posts strong enough for a deck?

Using 4x4 support posts for decks is not recommended due to their tendency to bow, even for decks at a low height. It is strongly advised to use 6x6 posts, regardless of local building code requirements.

8. Can I set deck posts without concrete?

Yes, it is possible to install deck posts without concrete by using post anchors. These anchors make it easy to secure fence posts without the need for cement or other types of anchoring. They also help protect wood from direct contact with damp soil, reducing the risk of rot.

9. Can you put deck posts in dirt?

While it is theoretically possible to sink posts treated for ground contact directly into the ground, the treatment may not have fully penetrated into a 6x6 post. It is recommended to use concrete piers with posts supported on metal post anchors for added stability.
