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.
This technique is used in our services for:
Typical Applications
How It Works
Our proven methodology ensures consistent, high-quality results for every installation.
Top Anchor Installation
Anchor rows are drilled at the top of the slope to secure the mesh system.
Mesh Deployment
High-strength steel mesh is unrolled down the slope from crest to toe.
Edge Tensioning
Mesh is tensioned and secured with edge ropes and perimeter anchors.
Catchment Preparation
Falling rocks impact the mesh and are guided downslope into a ditch or berm.
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.
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

Pinned Mesh Systems
Pinned mesh systems combine steel mesh with rock bolts or dowels to create a secure, reinforced slope surface. This containment system prevents loose blocks from detaching and provides long-term stability in both civil and mining applications.
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.
Wire Rope Netting
Wire rope netting provides high-strength surface stabilization for steep, fractured, or unstable rock slopes. Built from interwoven steel cables, this system offers exceptional durability and energy absorption—making it ideal for demanding rockfall environments.
