Frequently Asked Questions (FAQs)

1. How deep should a concrete fence post be in the ground?

Dig your hole to the correct depth, allowing for the height of the fence panel and the gravel board. As a rough guide the hole should be a minimum 1/3 the height of the fence, so a 6 foot fence would need an 8 foot post in a 2 foot deep hole. Similarly, the hole should be three times the diameter of the post.

2. Are concrete fence posts more expensive?

Cost: Budget is a priority for many people; timber posts are much cheaper than concrete posts, both to buy and to install.

3. How much are concrete fence posts?

When you're installing a fence post, the amount of concrete you need will be calculated based on the diameter of your fence post and how high the post is above ground. Most fence post holes will need between 1 - 4 bags of concrete to securely hold the post in place.
