Fixing/install a fence post into concrete or a hard surface

Listed below is a step-by-step process for concreting in fence posts. This process applies to concreting wooden fence posts as well as concrete fence posts.

Choosing the perfect location

Place the fence post base support into position, where you would like the post to be. You want it in just the right place to line up with your fencing plan.


Dig the hole

Before you install a fence post into concrete, it is time to get digging! Your hole should be about three times as wide as the post and deep enough to ensure a solid foundation.

Treating the post

Treat your post with a wood preservative if it is timber. This step gives a shield against rot and water damage.

Mix the concrete

Whip up your concrete mix, think of the consistency of a chunky smoothie. You want it firm enough to hold the post, but not too runny.

Position the post

Mark out the positions of the bolt holes for drilling and remove the base support. Drill the holes and return the base support. Fix the base post in position using the concrete fixing bolts. Insert the fence post and tighten the bolts on the base support

Pour the concrete

Pour your concrete mix around the post, this gives your post a concrete blanket and a feeling of being all snug and secure.

Spirit level testing

Use a spirit level to ensure that the fence post is square. You will not want to have to endure a wonky fence for years to come.

Support the post

While the concrete sets, brace your post to keep it straight, this is like giving your post a little crutch to lean on.

Let the concrete set

Patience is key; let the concrete set properly. This is a good time for a well-earned drink and to admire your handiwork.

Finish and seal

Once set, you can add any caps, finials, or sealants to the post, this adds a classy final addition!
