Concrete Fence: Pro Tips for Homeowners

A concrete fence is strong and durable. It stands the test of time as it can withstand wet and windy winter months as well as summer. Every concrete post is reinforced with steel so as to increase its strength and its resistance to elements.  Concrete posts are the most preferred by contractors, specifiers, and homeowners. Furthermore, they require minimal care and maintenance because unlike wooden posts, they do not require painting.


Why are Concrete Fence Posts Most Preferred?

Concrete fence posts are the most preferred around the UK due to their durability. They are very strong and they cannot rot or degrade. A well-set concrete fence can remain intact for many decades thus giving you value for money.

Considerations to Make When Choosing Concrete Fence

When buying concrete posts, the first thing to consider should be size and weight. If for example, you need to put up a 6ft high fence, the posts need to be 8ft long. An 8ft concrete post weighs at least 28Kgs thus making it difficult to move it around. If you choose a conventional post, they are heavier than that for an 8ft post.

Concrete posts are available in recessed and morticed versions. They are used together with arris rails and featheredge boards during the construction of the fence instead of using already made concrete fence panels

Using concrete gravel boards lengthens the life span of a concrete post fence. the concrete boards are available within 180cm and 183cm dimensions. They come in these dimensions to fit in the concrete fence panel. There are also concrete gravel boards with nibs on each end. They usually have a width of 183cm. However, the nibs can be removed to reduce the width to 180cm.

Most concrete posts come with a slot down the length of the post on both sides. It is important to lift the panels to their full height if the slotted concrete posts are already set in the ground. The slots have a width of 50mm most of the time. This allows the timber fence panels to integrate well.

Types of Slotted Concrete Posts

  • Intermediate posts have slots on the two opposing sides of the post
  • The end post has only one slotted side for the end of a fence run
  • The corner posts have two slots at 90 degrees to each other. They are typically used when a fence run turns a 90-degree corner.

How to Install a Concrete Fence

When Installing a concrete post, first dig a hole paying attention to the fence panel and gravel board. the whole should have a minimum depth of 2 feet. The hole should have a diameter 3 times wider than the post. Having a perfectly dug hole will save you the tedious work of cutting the concrete post.

You can use a long, narrow fencing spade to make the work of digging the holes much easier. A post-hole digger too will make the work of removing soil from the holes easier.

Concrete posts are secured in the ground using post-mix concrete or a mixture of ballast and cement.  It is recommended to use 1.5 bags of post-mix concrete per hole. You will need to use water to activate the post-mix before using it.

Once your hole is well dug, place the post in and position it well then fill it with either the post-mix concrete or a mixture of ballas and cement. Make sure the concrete post does not touch the ground to ensure rainwater does not collect on its base.

If need be, keep adjusting the post to the right position until the concrete hardens. It takes approximately 20 minutes for the post-mix to harden. however, even after it has dried, the post can still be adjusted.  Once it has dried, lay your gravel board in place on the ground and use it to level your next hole. This will help you in making sure the fence is in a straight line. You could also use a builders line and pegs to make sure the holes are properly aligned.


Installation of Concrete Gravel Boards For Concrete Fence Panels

The gravel board protects your fencing posts or panel from the ground. It also gives the fence a solid base and thus protecting it from underground water.

During the erection of the concrete fence panel with concrete fence posts, the concrete gravel boards help the posts to slot successfully from the top. The concrete gravel boards can be later bedded into the concrete at the foundation of the post to give it more stability.
