Active slope protection system, Tecco-type high-tensile steel mesh. 50kJ energy capacity. Covers rock face to prevent rockfall. For highways, railways, mining. MOQ 500 m2, 10-20 day delivery.
The active slope protection system (also called Tecco mesh system or SNS active protection) is a surface-retention rockfall mitigation system. Unlike passive systems that catch falling rocks, the active system covers and stabilizes the rock face β preventing rocks from detaching in the first place.
## How Active Protection Works
1. **Mesh Coverage**: High-tensile steel mesh (Tecco G65/3) draped over rock face and anchored at top, bottom, and intermediate points 2. **Anchoring**: Soil nails or rock bolts (25mm diameter, 2-4m depth) transfer loads from mesh to stable ground 3. **Retention**: Mesh holds loose surface rocks against slope β prevents initial detachment 4. **Drainage**: Mesh openings allow water to drain β prevents hydrostatic pressure buildup 5. **Vegetation**: Mesh openings allow vegetation growth β long-term slope stabilization via root systems
## Key Advantages
- **Prevention vs Catching**: Active systems prevent rock detachment. Passive systems catch falling rocks. Active is preferred where slope is above infrastructure. - **Minimal Excavation**: No major earthwork required. Mesh conforms to existing slope geometry. - **Permeable**: Rainwater passes through mesh β no hydrostatic pressure. Vegetation can grow through. - **50kJ Capacity**: System rated to retain rocks up to 50kJ energy β approximately 500kg rock at 10 m/s. - **Aesthetic**: Mesh is barely visible from distance. Slope retains natural appearance. Vegetation growth enhances aesthetics. - **Long Life**: High-tensile steel wire with Zn-Al coating. 30-50 year service life.
