5 Fencing Questions + 1 Bonus: Your Questions Answered

Which posts should you use for chain-link fencing? Can a 3-metre-high fence support a privacy screen? Where should wire tensioners be installed? And why can a concreted end post actually start lifting out of the ground when the mesh is tensioned?

These are some of the questions we receive in the comments on our videos. In this new episode on the Rete Plastic YouTube channel, we answer five useful fencing questions, plus one rather unusual bonus comment at the end.

Can I raise a fence to 3 metres and add a privacy screen?

There are several ways to increase the height of an existing fence, including suitable post extensions. The main problem arises when a privacy or shade screen is added to the higher structure.

A standard T-post is not designed to withstand the high wind loads created by screening installed at a height of 3 metres.

The fabric prevents much of the air from passing through the fence, effectively turning it into a sail. Increasing the height also increases the leverage exerted by the wind on both the posts and their foundations.

When screening is required, post size, height, post spacing, braces and foundations must therefore be considered together.

Where should wire tensioners be installed?

A wire tensioner is used to tension and maintain the horizontal wires supporting the mesh.

It can certainly be positioned next to a post. During our installations, however, we sometimes place tensioners in less visible positions.

There is also a practical reason: when one coil of tension wire ends and another has to be joined, an additional tensioner may be required at that point.

There is therefore no single compulsory position. What matters is creating an effective tensioning system that also remains accessible for future adjustments.

Round posts or T-posts?

Both can be used with chain-link fencing.

Round posts are generally more expensive but can offer additional features, including protective galvanising and coating, welded wire hooks and a top cap. They also tend to provide a more refined appearance.

A T-post, on the other hand, is a simple, practical and economical solution.

The choice should also be appropriate for the type of mesh. With lightweight, inexpensive mesh, a T-post may provide the most balanced solution. For higher-quality fencing or where appearance is particularly important, round posts can be an excellent alternative.

At Fenceshop.eu you can find fencing mesh, posts and accessories for different types of fencing projects.

Why do the end post and brace lift out of the ground?

If the end post and brace begin to move or lift while tensioning the wires or mesh, the most likely cause is an undersized concrete foundation.

Tension wires can generate considerable force at the end of a fence. If the concrete footing is too small, it may not be able to resist that force.

First, avoid overtensioning the wires.

If the problem has already occurred, the wires and mesh can be loosened, the area around the end post excavated again and a larger concrete footing constructed before the fence is retensioned.

How many tensioners are required for 100 metres of fencing?

For a straight 100-metre section without corners, steps, gates or interruptions, one tensioning point for each horizontal wire can work.

However, the number changes as soon as the fence is divided into separate sections.

Corners, gates, changes in level and new starting points interrupt the continuous run. Each interruption may therefore require an additional tensioner for every tension wire.

The correct number depends not only on total fence length but also on its layout.

And the bonus question?

Not every comment is technical.

Under our video about installing fencing without concrete, someone simply wrote: “What kind of video is this?!”
