GBE Rockfall Protection Barriers
FOR THE MOST VALUABLE ASSET IN LIFE: OUR SAFETY
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.
WE CAN PROVIDE YOU WITH THE COMPLETE SAFETY PACKAGE
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.

QUALITY YOU CAN RELY ON.
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.
WE DON'T LEAVE SAFETY TO CHANCE.
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.
