1. Riverbank Erosion: Engineering Challenges & Solutions
Riverbank erosion causes land loss up to 3.38 km²/year in high-flow rivers. JOESCO gabions combat this with:
- Triple-Layer Corrosion Defense: 2.0–4.0mm steel wire with 215–275 g/m² zinc coating + PVC options for saltwater.
- High-Velocity Resistance: Hexagonal mesh (80×100mm/100×120mm) withstands flows up to 6 m/s.
- Modular Stability: Baskets (1.5–6m L × 0.5–3m W) with diaphragms resist hydraulic pressure.
2. Field-Proven Protection Systems
Adapting river management frameworks, JOESCO provides:
✅ Deep-Water Zones: Sack gabions + mattresses as anti-scour aprons.
✅ Sloped Banks: Layered gabion boxes (0.23–1.5m H) with 3D erosion control mats.
✅ High-Retreat Areas: Hybrid RCC structures + gabion dykes.
3. Ecological & Economic Advantages
- 50-Year Lifespan: Minimal zinc loss in salt-spray tests.
- Permeable Design: 60% faster ecosystem recovery vs. concrete walls.
- Cost Efficiency: 35% faster installation + accepts local recycled aggregates.
