# Tutorial for setting up poles

## Calculating the height of a pole

Once the height of your fence is known, depending on the desired use, you obtain the useful overhead height (A - diagram below).

The buried part of the stake (B - diagram below) must be equal to one third of the aerial height. The following diagram gives the total required length of the stake (H = A + B).

â€‹

The stake must be buried 1/3 of its length. Which means that B = 1/3 H Example: a 1.8m stake will be inserted 60cm and protrude 120cm.

When stony ground prevents the sinking of an acacia post to the recommended depth (one third of its height), an effective solution consists of creating aconcrete ring around its base. This concrete ringprovides a solid foundation at the post, compensates for the lack of depth, andalso promotes water drainage to avoid damage to the wood. To do this, dig a small ditch around the post, pour fresh concrete into it, smoothing it outwards to facilitate water drainage. This method secures the post robustly, even in difficult ground.

To support the tension of your fence effectively, it is essential to place a support strut at each corner and in each direction of the fence. Make sure they are the same height as your posts and attach them about 1/3 the height of the post they are reinforcing. In some cases, such as tall posts, heavy loads or extreme weather conditions, the use of two struts is recommended.

## Spacing between poles

One of the most frequently asked questions, what spacing is needed between the acacia posts of my fence?

Here is a breakdown of the recommended heights and spacing in meters for each type of animal, whether domestic livestock or wild animals:

â€‹

Domestic Livestock:

1. Cattle:

• Height of the fence: 1.3 meters

• Spacing between stakes: 4 meters.

2. Horses:

• Height of the fence: 1.3-1.8 meters.

• Spacing between stakes: 3 meters.

3. Sheep and Goats:

• Height of the fence: 1 to 1.2 meters.

• Spacing between stakes: 3 to 4 meters.

• Use narrow mesh fencing to prevent small animals from falling through.

4. Pigs:

• Height of the fence: 0.9 to 1 meter.

• Spacing between stakes: 2.5 to 3 meters.

• Make sure the fence is securely anchored to prevent pigs from knocking it over.

Wild animals :

1. Boars:

• Height of the fence: 1.3 meters.

• Spacing between stakes: 3 to 3.5 meters.

• Make sure you have a sturdy underground fence to prevent digging.

2. Deer:

• Height of the fence: 2.5 to 3 meters.

• Spacing between stakes: 3 to 4 meters.

• Stretch the fence tightly to eliminate gaps.

3. Wolves:

• Height of the fence: 2.5 to 3 meters.

• Spacing between stakes: 2.5 to 3 meters.

• A solid underground fence is necessary to prevent digging.

A properly tensioned fence will prevent animals from lifting it or passing through it. For example, the wild boar passes its snout through the mesh of a fence. If he feels that it is flexible, he will push until he crosses it. No matter how strong the knotted mesh is, the mesh will come undone. Whereas if the fence is tight, the wild boar will feel the tension in the fence and will not try to push to cross it.
