Gabions

Coastal Protection: Gabions

What are they? - Wire cages usually filled with crushed rocks, and then piled up along the shore to prevent or reduce coastal erosion by weakening wave energy.

Stability? - Short term protection of 5 to 10 years.

Durability- Wires need constant maintenance as they are easily corroded by seawater. They are also affected by excessive trampling and vandalism.

Problems - They are unsightly and can become a danger along the beach.
