Coastal Gabion Solutions for Erosion Control & Shoreline Protection

Our coastal gabion systems are engineered to withstand harsh marine environments, providing durable and sustainable solutions for shoreline stabilization, erosion control, and coastal infrastructure protection. Manufactured from high-grade materials with superior corrosion resistance, these gabions are designed to combat saltwater exposure, wave action, and tidal forces while maintaining structural integrity and environmental compatibility.

Key Features & Benefits:

  • Marine-Grade Corrosion Resistance: Triple-protection coatings (Galfan + PVC optional) provide 3-5x longer service life in saltwater environments compared to standard galvanized products.

  • Wave Energy Dissipation: Porous structure effectively absorbs wave impact, reducing scour and preventing undermining.

  • Flexible Design: Adapts to settling and shifting coastal soils without losing functionality.

  • Natural Drainage: Permeable design prevents hydrostatic pressure buildup while allowing natural water filtration.

  • Ecological Benefits: Promotes marine vegetation growth and provides habitat for aquatic organisms.

  • Cost-Efficiency: 30-50% lower installation costs compared to concrete breakwaters or revetments.

Technical Specifications:

  • Mesh Type: Double-twisted hexagonal (80x100mm standard)

  • Wire Coating: Galfan (Zinc-5% Aluminum) base + optional PVC encapsulation

  • Wire Diameter: 2.7mm-4.0mm (marine-grade thickness)

  • Tensile Strength: 450-550 MPa (meets EN 10223-3 standards)

  • Design Life: 25-50 years depending on environmental conditions

Coastal Applications:

  • Seawalls & Revetments: Protection against coastal erosion and storm surge damage

  • Breakwaters & Groynes: Offshore structures to reduce wave energy and maintain beaches

  • Cliff Stabilization: Preventing coastal landslide and rockfall hazards

  • Boat Ramp Protection: Armoring launch areas against scour and erosion

  • Marsh Restoration: Creating sustainable boundaries for wetland rehabilitation

Performance Data:

  • Withstands wave heights up to 3-4 meters when properly engineered

  • Resists seawater corrosion at 10x the rate of standard galvanized wire

  • Reduces erosion by 70-90% in typical coastal applications

Case Study Example:
Deployed 2,500 cubic meters of PVC-coated gabions for [Client Name]'s seawall project in [Location], achieving 100% erosion control despite Category 2 hurricane conditions in 2023.

Sustainability Advantages:

  • Natural Appearance: Blends with coastal landscapes better than concrete

  • Habitat Creation: Surface colonization by marine life enhances biodiversity

  • Carbon Footprint: 60% lower embodied energy compared to concrete alternatives

  • Material Sourcing: Uses locally quarried stone, reducing transportation emissions
