Draped Mesh Systems

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.

Understanding 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 in steep, inaccessible terrain.

This passive containment approach is ideal for emergency rockfall mitigation and long-term protection of transportation corridors.

Process

How It Works

Our proven methodology ensures consistent, high-quality results for every installation.

1

Top Anchor Installation

Anchor rows are drilled at the top of the slope to secure the mesh system.

2

Mesh Deployment

High-strength steel mesh is unrolled down the slope from crest to toe.

3

Edge Tensioning

Mesh is tensioned and secured with edge ropes and perimeter anchors.

4

Catchment Preparation

Falling rocks impact the mesh and are guided downslope into a ditch or berm.

Benefits

Key Advantages

Rapid Deployment

Draped mesh can be installed quickly for emergency rockfall protection, often in days rather than weeks.

High-Volume Capacity

The draping design allows accumulated debris to travel to catchment areas, maintaining system effectiveness over time.

Minimal Drilling

Only top-of-slope anchors are required, reducing installation time and cost compared to pinned systems.

Steep Terrain Access

Rope-access installation techniques allow coverage of vertical and overhanging faces.

Low Maintenance

Periodic debris removal at the base maintains system capacity with minimal ongoing intervention.

Engineering

Technical Considerations

Soil/Rock Conditions

Top anchors must reach competent rock or soil. Slope face conditions determine mesh type selection and edge anchoring requirements.

Groundwater

Drainage is unimpeded—mesh systems do not trap water. Weep drains may be integrated for slopes with seepage.

Load Capacity

Mesh strength rated by wire diameter and pattern. High-tensile systems handle larger block sizes and higher impact energies.

Spacing

Top anchor spacing depends on mesh weight, slope angle, and wind loading. Edge anchors secure perimeter and panel seams.

Installation Method

Mesh panels deployed from crest using cranes, helicopters, or rope-access crews. Panels laced together with high-strength clips.

Equipment Used

  • Helicopter or crane for mesh deployment
  • Rope-access rigging systems
  • Drill rigs for anchor installation
  • Seaming clips and lacing tools
  • Edge rope tensioning equipment

Limitations

  • Requires adequate catchment area at base
  • Not suitable for areas requiring stabilization (containment only)
  • Debris accumulation requires periodic removal
  • High wind areas may require additional anchoring

Questions

Draped Mesh Systems FAQ

Draped mesh hangs freely from top anchors and guides debris to catchment areas. Pinned mesh is bolted directly to the slope face, actively containing loose material in place. Draped is faster to install; pinned provides active stabilization.
Debris should be removed from catchment areas periodically—typically annually or after major rockfall events. The mesh itself requires minimal maintenance with periodic inspection of anchors and seams.
High-tensile mesh systems can contain rocks up to several tons. For very large blocks, wire rope netting or hybrid systems may be recommended. We assess expected rock sizes during design.
Installation speed depends on access and slope conditions. Rope-access crews can install thousands of square feet per day. Emergency projects can be operational within days of mobilization.
Yes, draped mesh is highly effective on vertical and near-vertical faces. Our rope-access crews specialize in these challenging installations where conventional equipment cannot operate.
