Different Types Of Concrete Fence Posts
As the name suggests, corner posts go on the corners of the fence where they hold two fence panels at a right angle.
Slotted or intermediate posts sit in the middle of two fence panels where they hold a panel each side.
End posts sit on the end of a run and therefore feature only one slot to hold once fence panel.

Safety and Precautions
Before you even start installation process, it’s important to take some safety precautions.
It’s important that you check for any pipes or electrical mains running under the area before you begin the digging process.
Step 1: Find The Correct Position
The first step is to find the correct position of where the posts will go.
This will depend on the size and type of fence you’re installing.
Once you’ve found the correct position, mark out the area with some stakes and string. This will give you a clear guide to follow when you’re ready to start digging.
Step 2: Dig The Hole
The next step is to start with the digging process. A hole for a fence post should be a minimum of 2ft (600mm) and around three times the width of the post.
You will need to keep the depth of the hole in mind when deciding how high you want your fence to be.
For example, if you require the height of the fence to be6ft tall, then 8ft fence posts are required.
This is because the post will be going 2ft into the ground, which means that once you place it in the hole, it will now be 6ft in height.
Step 3: Place The Post In The Hole
You should now place the concrete fence posts into the hole one by one.
The corner or end posts should be inserted first. To ensure that the post is vertically level, make sure to use a spirit level.
Once you have the post level, you can then fill with concrete mix or post fix.
Hold the post in place for a few minutes until you notice that it’s beginning to set.
Step 4: Wait
Before you slot in the fence panels, it’s best to wait 24 hours for the concrete to set.
This will ensure that your fence posts are secure and won’t move when you come to slot in the fence panels.
Step 5: Add The Fence Panels
Make sure to install any gravel boards before sliding in the fence panels.
After you have waited the necessary time, you can then slot in your fence panels.
The fence panels are slotted into the groves that are found on the edges of the concrete fence posts.
How To Install Concrete Fence Posts On A Slope
If you’re installing your concrete fence posts on a slope, then there are a few things that you need to do differently.
Here’s are a few methods on how to do it.
Method 1: Racked Fence
With this option, the fence posts sit perfectly vertical in the ground, whilst the bottoms of the panels are the same distance from the bottom of the ground at all times.
You will also have two different options for the top of the fence.
Method 2: Stepping Fence
Generally used on a steeper slope, stepping is where you connect 2 fence panels to one post at different heights.
The downside to a stair step fence is the gaps that will appear under each panel. This means that small animals will be able to enter your garden using these gaps.
The solution to this is to use custom cut pickets.
Frequently Asked Questions

Can Concrete Fence Posts Be Painted?

You should then prime the concrete to help the paint to adhere, and finally paint the concrete with something such as a masonry paint, which is a better choice than just standard fence paint.
Can You Drill Into Concrete Fence Posts
It is possible to drill into concrete fence posts, providing you use the correct tools. An SDS hammer drill is required along with masonry drill bits. The key to successfully drilling into concrete posts is to start with a small drill. For example, start with a 4mm drill bit and gradually work up to 6mm, 8mm, until you reach the required size.
