The danger of rockfalls is increasing due to climate change. This affects notonly mountainous regions but also growing urban areas located close to rocky slopes. in order to provide the greatest possible safety at these loca-tions, 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.

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.

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.

Pre-assembled

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, mainly 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 certifica-tion 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
