Protecting people is the top priority

True to this guiding principle, we place particular emphasis on reliable and scientifically tested protective systems that meet the highest standards and are precisely adapted to your needs and requirements.

 

Our experience for your safety

Know-how from decades of experience and successfully implemented projects all over the world, as well as close cooperation with research institutes and international experts, make PFEIFER your reliable partner.

The need for safety systems and protective structures is increasing worldwide

Economic development and the built environment are continuously growing. A network of roads, railways and runways extend to even the remotest of areas. Increasingly challenging terrain is being developed to enable this growth.

Development in hazardous areas has increased the need for risk mitigation. Landslides, rockfalls and avalanches are examples of such hazards that can cause enormous property damage and threaten personal safety. And these risks are increasing. Progressive climate changes and expanding human intervention in nature is leading to a significant rise in potential hazards.

We have made it our business to minimize these risks and make things as safe as possible. We utilize modern research, intelligent technology and decades of experience to understand natural hazards and create solutions to ensure your safety.

PFEIFER Rockfall Protection Barriers
PFEIFER Rockfall Protection Barriers

Rockfall barriers based on over 35 years of testing and development experience, on one hand side being fully tested and safe, on the other side very well optimized cost wise:

  • Easy to install due to lightweight elements and very simple modular structure, easy to build and service
  • Modularity allows easy customisation (for multi-hazards)
  • Brake elements – extremely simple and easy in inspection and exchange (activation points clearly visible)
  • Elements designed to keep their parameters over the whole lifetime
  • Shorter anchoring due to lower anchor forces
  • Capable to stop also fast moving, smaller rockfalls (anti bullet effect solution) Watch example video here.
  • Can be easily equipped with warning or monitoring systems

Technical description

  • CE marked in class A (acc. EAD 340059-00-106, previously ETAG 027) as well as FOEN (BAFU) in Switzerland tested and certified
  • 100 – 5000 kJ dynamic capacity
  • 2.0 – 9.0 protection height
  • Main nets made out of high tensile steel (min.. 1770 MPa)
  • Tested high tensile secondary mesh on request (capacity of 675 kJ/m2)

PFEIFER Slope Stabilization System

High tensile steel in the form of the double twist mesh – unique and optimal balance between tensile strength and stiffness together with membrane effect, offering the following customer values:

  • Perfect material for slope facing in combination with all market available soil-nails and rock bolts
  • Optimal behavior as a rockfall drape
  • Capable of any geological conditions (soft-soils, weathered and fissured rock, flysch etc.)
  • Very high resistance against punctual loads and load transmission in both directions (vertical as well as horizontal)
  • Full self-healing effect in case of wire cut (no capacity loss)
  • Very long lifespan due to the best available corrosion protection
  • Easy installation due to fully controllable unrolling effect and low weight of the material
  • High material availability due to high production capacity

Technical description

  • Tensile strength of min. 175 kN/m (lengthwise) with the weight of only 1.9 kg/m2
  • Very high puncturing resistance allowing to work with normal anchor plates as well as with special ones
  • Punching resistance acc. EAD 230008-00-0106 – over 200 kN
  • Maximal deformation below 7% (at 150 kN tensile load)
  • Corrosion protection Zn/Al class A, tested for over 2000 hours in salt spray tests
  • Mesh to mesh connections using system clips (no overlapp necessary)
