How to Build a Fence on New Jersey Barriers

Hello everyone, we are from Fenceshop, the e-commerce of Rete Plastic, and today we want to talk to you about how to build a fence on New Jersey barriers. First of all, what are New Jersey barriers? They are cement elements primarily used to delineate highway lanes. They are known for their inverted T shape and robustness and can be two, three, or four meters long. They are often used on construction sites to create temporary perimeters because of their ease of placement with cranes or forklifts.

Is it possible to fence on New Jersey barriers?

Yes, it is possible to fence on New Jersey barriers. There are two main types of New Jersey barriers: with and without holes. If the New Jersey barriers have holes, it is possible to cement the posts inside them, as if it were a hole in the wall. If the New Jersey barriers do not have holes, the post must be bolted. In this case, we recommend paying close attention to how the gate is fixed, as it may tip over due to the force exerted when opened. To avoid this problem, it is advisable to make holes and create footings next to the New Jersey barriers to cement the posts.

The pitfalls of bolting a fence on New Jersey barriers

One of the main problems in bolting a fence on New Jersey barriers is that not all of them have a top surface wide enough to accommodate a fence plate. If the surface is too narrow, there is a risk of breaking the edge of the New Jersey barrier. Even the use of screw anchors can cause the edge to break. A common solution is to turn the plate in the direction of the mesh, bolting it in the center of a reduced space, which can be as narrow as 7 centimeters.

Modular fences

This reasoning applies both to mesh fences, such as Stilplax, Vortek, and Bahia meshes, and to modular panels. A robust but costly solution is the use of adu plates, which embrace the top and part of the sides of the New Jersey barriers, providing greater security. However, it is important to evaluate the costs, since an important plate may cost more than the post and mesh combined.

Recomposable fences

If you want the fence to be easily recomposable, consider the idea of ending and starting the fences inside the same New Jersey barrier. This allows for easy movement of the modules with a forklift, making it possible to recompose the fence in another area. However, this method requires more posts and can increase the costs.
