GBE Rockfall Protection Barriers


The danger of rockfalls is increasing due to climate change. This affects not only mountainous regions but also growing urban areas located close to rocky slopes. In order to provide the greatest possible safety at these locations, we have developed our GBE barriers using high-tensile steel wire mesh. Despite the possible high impact energies of up to 3000 kJ we are able to keep the anchoring forces very low thanks to our unique system design. This combined with an easy installation make the GBE series an extremely reliable and economical protection solution.


At your request we can take on the role of consultant, planner and even project manager. Both the solutions we offer and the quality of our customer service is valued by our customers. For us excellent service is an integral part of every single project. No matter which phase of the project you are in, we will provide you with the support and expertise required to achieve the best results – saving you both time and money.

Our GBE series is remarkable because of its cost efficiency while at the same time meeting the strictest safety standards. The low weight and low anchoring forces of this series enable a quick and inexpensive installation. Our meshes are made of high-tensile steel wire, ensuring the lowest weight-to-strength ratio to achieve high stability. This is why our systems are particularly unobtrusive in the landscape.

GBE barriers provide the following features

High-tensile steel wire mesh

Protection against dynamic loads of up to 3000 kJ. Some of the energy is dissipated by means of elastic/plastic net deformation while the majority is dissipated by the braking elements.

Low anchoring forces

Short anchors are sufficient. This significantly lowers drilling time during installation and therefore the overall costs of the project.


The posts are delivered to the construction site as modules with pre-installed bundles of mesh. This significantly reduces the installation time as well as making the process easier.

High safety standards

Our barriers fulfill the ETAG-027 guidelines, most of them bear the CE mark, and are tested according to the most demanding method in vertical free fall.

U-brake with stainless steel

This component enables linear energy dissipation and is easily accessible for inspection and maintenance. Stainless steel makes the brake extremely durable even when subjected to strain.

Light and unobtrusive

The low weight of the barrier means that it can be easily installed. With its high-tensile steel wire and innovative design, this solution conserves materials, protects the environment and is virtually invisible from a distance.

First-class corrosion protection

The corrosion protection of our systems will last for generations. This means that our customers benefit from particularly low maintenance costs.



All Geobrugg systems are developed in Romanshorn, Switzerland. They are tested under the supervision of and in cooperation with research institutes and certification bodies – using test facilities including the world's first for the rockfall barrier approval tests. Our customers can be sure that GBE barriers meet the highest standards.

  • Tested the most demanding way: vertical, free fall
  • All energy categories for the GBE series are approved in accordance with European Directive ETAG 027

Special Barrier GBE-100A-R (Fast Installation and Less Drilling)

The GBE-100A-R rockfall barrier provides protection against impact energies of up to 100 kJ and is quick and simple to install. This system is ideal for use on limited space, on top of retaining walls, or even as a temporary fence on construction sites.


This system with high-tensile TECCO® steel-wire mesh is setting new standards in the lightweight rockfall barrier field and provides particularly efficient protection against impact energies of up to 100 kJ. We have designed this barrier to work with-out upslope anchors. This reduces drilling costs and makes the system quick to assemble.

Setting up the posts

Once the posts are set up, they are fixed onto the rock or foundations with two anchor rods.

Installing ropes

Thanks to the inserting aids, the support ropes are pulled through the preassembled net bundle with just a few moves.

Hoisting the net

The nets bundled onto the posts are then released and pulled across the support ropes effortlessly like a curtain.


GBE-100A-R barriers boast the following features:

Certified twice

The barrier meets ETAG 027 and FOEN guidelines bear the CE marking and has been tested in accordance with the most demanding of methods – in vertical free fall.


The posts are delivered as modules with pre-installed mesh bundles. This significantly reduces the installation time and minimizes the assembly steps.

Fewer anchors

As no retaining ropes are necessary, only a few anchors are required. This reduces drilling work and reduces overall project costs.


High-tensile steel wire mesh

The TECCO® G80/4 mesh made of high-tensile steel wire with a tensile strength of more than 1,770 N/mm2 provides reliable protection against dynamic loads.

First-class corrosion protection

The corrosion protection of our systems will last for generations, ensuring that our customers benefit from particularly low maintenance costs.

Light and unobtrusive

As there are no brake elements and the structure uses lightweight components, the barrier is very discrete in aspect
