High-Energy Rockfall Barriers
High-energy barriers provide advanced rockfall protection for slopes where large blocks, high drop heights, or extreme impact forces exceed conventional barrier capacity. These systems absorb up to 10,000 kJ through flexible ring nets, energy-dissipating brakes, and engineered post foundations.
Understanding High-Energy Rockfall Barriers
High-energy barriers provide advanced rockfall protection for slopes where large blocks, high drop heights, or extreme impact forces exceed conventional barrier capacity. These systems absorb up to 10,000 kJ through flexible ring nets, energy-dissipating brakes, and engineered post foundations.
Certified to European ETAG 027 standards and proven worldwide, high-energy barriers protect critical infrastructure from catastrophic rockfall events.

Rock Anchoring Typical Applications
How It Works
Our proven methodology ensures consistent, high-quality results for every installation.
Trajectory Analysis
Model rockfall paths, velocities, and energies to determine optimal barrier location and capacity.
Foundation Installation
Install drilled anchors or concrete foundations sized for design impact loads.
Post Erection
Erect hinged steel posts with energy-absorbing brake elements and guy cables.
Net Installation
Mount certified ring net panels with proper overlap, tensioning, and perimeter connections.
Key Advantages
Extreme Energy Absorption
Ring nets and brake elements absorb impact energies up to 10,000 kJ—far exceeding conventional barriers.
Certified Performance
ETAG 027 certification provides verified, documented performance for design engineers and owners.
Flexible System
Net deformation absorbs energy progressively, preventing catastrophic failure under extreme loads.
Serviceable Design
After impacts, damaged nets and brakes can be replaced while foundations and posts remain in service.
Long Service Life
Galvanized components provide decades of service with periodic inspection and maintenance.
Technical Considerations
Soil/Rock Conditions
Foundations must resist extreme dynamic loads. Rock anchors or concrete foundations sized based on energy rating and site geology.
Groundwater
Barriers are permeable. Foundation drainage may be required for stability in wet conditions.
Load Capacity
Energy rating determined by rockfall modeling. Block size, drop height, and slope geometry determine required capacity.
Spacing
Post spacing per manufacturer specifications for certified energy rating. Closer spacing may increase capacity.
Installation Method
Foundations installed first, posts erected with brake elements, nets mounted and tensioned per certification requirements.
Equipment Used
- Drill rigs for anchor installation
- Concrete mixing and placement equipment
- Crane for post and net erection
- Rope-access crews for steep terrain
- Tensioning equipment
Limitations
- Higher cost than conventional barriers
- Requires certified installation
- Foundation requirements in poor ground
- Rockfall modeling required for design

Draped Mesh Systems
Draped mesh systems control loose rockfall by capturing debris and guiding it downslope to a safe catchment area. Unlike pinned mesh, draped systems are not rigidly attached to the entire slope—allowing them to manage high volumes of material efficiently.
Mid-Slope Attenuators
Mid-slope attenuators are hybrid rockfall protection systems positioned partway down a slope to intercept falling rocks before they gain full momentum, reducing energy and enabling more efficient catchment at the base.
Rock Scaling
Rock scaling removes loose, hazardous material from rock slopes to prevent rockfall before it occurs. Using rope-access crews, excavators, and specialized tools, scaling is often the first and most essential step in any rockfall mitigation program.
Rockfall Barriers & Fences
Engineered catch systems that intercept falling rock or debris before it reaches roadways, railways, or infrastructure. These high-energy systems absorb and dissipate impact energy safely through deformable components.
