How to Set Fence Posts

It’s important to know how to set fence posts when installing your own fencing. As you know, the fence posts hold the whole fencing system up, just as the framework for a building does. It’s not an overly complicated task. However, it must be done properly, to ensure that your fence line stays set, fence panels or other fencing stays secure and erect for years.

The Importance of Setting Fence Posts

Installing quality fencing keeps your property, livestock, gardens, family or businesses secure. So, start this DIY task off right, by knowing how to set fence posts, and the rest of the process will literally settle nicely into place.

Only use the best quality products, purchased from a known and proven dealer of fencing like AVS Fencing Supplies. They have the best quality fence posts, other materials and tools to set your fence posts and entire fence systems…but, more on that later.

What to Use

Wooden fence posts are commonly used for gardens and perimeter fencing for homes, for their natural look. Typical height of this and most fencing is around 1.8m, so a fence post of 2.4m would be used, including depth into the surrounding ballast and cement (ratio: about 6:1) or postmix. “Surrounding” means you don’t want this mixture underneath the post where it can hold water, upping the odds of wood rot.

This same basic method is used for concrete fence posts, so the same knowledge on how to set fence posts applies. Such posts come in many different sizes like wooden posts, and are often used to hold up easy-use fencing panels. The hole size depends on the post size.


Shingle bases should underlie cement posts to act as a barrier in areas where water doesn’t readily drain away from the earth. Always ensure vertical alignment with a spirit level, and adjust posts to stay erect. Scrap wood bracing and brackets can help with this process, but AVS’s trained staff will explain the details.

When using concrete gravel boards as your fencing base, secure panels into the cement-ballast or postmix. If you know how to set fence posts made of cement, you realise this keeps the fencing from wicking up ground moisture and decaying the fence. AVS sell slotted, easy to use concrete cement posts for quick slide-in fence panels. Such panels make for easy stepping of fence segments on sloping property.

AVS also sell morticed concrete fence posts for easy installation of timber rails that are the horizontal support for beautiful open-view palisade fencing or more tightly constructed closeboard fencing. These offer another simple option good to know about when considering how to set fence posts. Rectangular holes in the sides of morticed concrete fence posts allow for easy insertion of supporting timber cross rails.

Metal fence posts, often used for chain link fences, are also usually best secured in a solid mixture base. Learn how to set fence posts from the helpful staff at AVS’s many centres, and you’ll be advised to plant metal posts’ base plates securely in the mixture.

Buying AVS timber posts means you’re purchasing from increasingly UK-sourced sustainable forests, so you’re supporting the environment. Getting only the top quality fencing materials, tools and attachments from AVS supports your fencing for a lifetime!
