HLE Nets, HR Mesh, and three-dimensional geogrids

What Are HLE Nets and HR Mesh?

HLE nets (High Elastic Limit) and HR mesh (High Resistance) are innovative technical solutions perfectly suited to:

  • Landslide prevention and remediation.
  • Cliff stabilization, effectively retaining falling stones and rock blocks.
  • Providing an economical and visually integrated alternative to traditional nailed walls with shotcrete.

Advantages of HLE Nets and HR Mesh

1. An Alternative to Shotcrete

  • Equivalent Resistance: These solutions offer strength comparable to 20 cm reinforced shotcrete.
  • Cost Reduction: Up to 2 to 3 times less expensive than traditional shotcrete.
  • Ease of Implementation:
    • Fewer weather-related constraints.
    • No reliance on concrete quality or specific site conditions.

2. Landscape Integration

  • Unlike the dull gray of shotcrete, these systems allow for natural or assisted revegetation (manual or mechanical seeding).
  • The result: a visually appealing green surface, creating a natural grassy slope effect that enhances aesthetic acceptance.

3. Versatility

  • Combines surface protection and high resistance to the forces that trigger landslides.
  • Well-suited for loose terrain, where long anchors are needed to traverse potential slip circles.

4. Superior Resistance

  • HLE nets and HR mesh vastly outperform standard tensioned mesh (single or double layers), providing robust stabilization.

Implementation and Technical Design

  1. Anchor Grid:
    • The anchor layout remains the same as for a traditional nailed wall.
    • Long anchors are pre-tensioned, holding the terrain and mesh under constant tension, which blocks the forces promoting landslides.
  2. Integration with Vegetated 3D Geogrids:
    • When coupled with three-dimensional geogrids, they provide dual benefits:
      • Erosion Control: The geogrid structure reduces surface runoff and erosion.
      • Facilitation of Revegetation: Supports rapid revegetation, ensuring optimal landscape integration.

When to Opt for HLE Nets and HR Mesh?

These solutions are particularly suited when:

  • A cost-effective and quick alternative to shotcrete is needed.
  • Landscape integration is a critical criterion for the project.
  • The terrain requires preventive or curative reinforcement against landslides while ensuring effective retention of stones and blocks.

A Durable and Cost-Effective Investment

By halving or even tripling cost savings compared to traditional nailed walls and providing equivalent resistance, HLE nets and HR mesh stand out as an economical, aesthetic, and high-performance solution for stabilizing unstable terrain.
