What Is Fence Post Reinforcement?

Reinforcing a fence post is making it more stable and stronger to cope with external factors such as storms or physical collisions. Ultimately, the fence strength relies on how structurally sound the fence posts are, which depends on installation and materials.

The deeper in the ground the post goes, the more chance it will stay strong above it. For some perspective, there are three general variations of how to fix wooden fence posts.

  1. The fence post is placed in the ground and covered with the earth from the hole
  2. The fence post is placed in the hole and secured with concrete
  3. The fence post is placed, secured with concrete, and reinforced with supports or fixers.

There are other variations to how you can reinforce a fence post. For example, a fence post can be reinstalled directly within the hole in the ground, as well as reinforced from the outside with wood, concrete, or steel. Both reinforcement methods can be applied to the fence post, ensuring it’s as strong as possible.

Are Concrete Fence Posts Reinforced?

Concrete fence posts are reinforced, typically with four internal steel reinforcing bars (rebar). Notoriously, this solution is the strongest available. While timber posts are susceptible to rot and steel rust, reinforcement concrete fence posts last significantly longer.

However, despite the name, it’s not necessarily the concrete that makes this fence post solution strong, it’s the reinforcement bars inside the concrete. So, if you’re building a new fence or replacing a fence post, then we highly recommend applying a reinforced concrete solution.

You can install this post the same as you would if it was wooden. However, it’s much heavier to manoeuvre. Therefore, we recommend using more than one person for the job.

How to Reinforce a Fence Post

Reinforcing a fence post can be achieved with different techniques and materials. The best methods depend on a few factors, such as the material you wish to use, the size of the fence and whether you’re fixing an old fence post or building an entirely new fence.

How to Reinforce a Wooden Fence Post

If you’re working with a fresh wooden fence post, you can reinforce it from the start to avoid repair later. Reinforcing a wooden fence post can come from beneath the ground and from the outside.

Firstly, dig your hole relative to the size of the post. The hole depth should be at least a third of the post length (90cm post – 30cm hole depth). Before placing your fence post in the ground, take the opportunity to add some extra reinforcement.

This addition could include galvanized wood screws to remain 4-5 inches on the outside or reinforced concrete or steel support fixes that can be attached to the post above and beneath the ground.

Next, fill your hole with gravel, stones, or rubble before pouring in the concrete mix. It’s important to make sure that the post is level while it sets. Any extra reinforcement can be installed on the outside with wooden, steel, or concrete support beams to help stabilise the fence post.

How to Reinforce a Vinyl Fence Post

Once again, vinyl fence posts are strengthened with concrete and steel reinforcement methods. Securing a vinyl fence can be achieved with steel metal sleeves which are popular to attach to the vinyl posts, alongside ensuring the fence is tight enough around the perimeter.

Often, vinyl fences can become damaged because the panels, posts, and rails were not tight enough in the first place. Before attempting to fix or replace a vinyl fence post, ensure all rails, pickets and posts are tightened.

How to Reinforce a Leaning or Rotting Fence Post

There are a few solutions available for fixing fence posts, depending on the material and damage.

Firstly, you need to assess the damage. To understand the extent of damage, test the post with your hand to determine if it’s intact. Unfortunately, if the fence post is broken, without steel sheets or concrete reinforcement supports, we suggest you remove it entirely and replace it.

Secondly, to reinforce the fence post, you should dig a few inches of soil around it to give yourself space beneath the ground next to it. In this space beneath, add gravel, stones, small rocks, broken bricks and rubble before filling the hole with concrete and leaving it to set.

Finally, attach steel sheet fixes or concrete supports to the fence post for extra stability. This way, even if the post is broken, you don’t have to replace it.
