Gabion Baskets
Gabion has traditionally been used for retaining walls due to its low cost compared to conventional methods.
- Rock Gabions – Durable, Sustainable Retaining Solutions
- Engineered for strength and designed for longevity, rock gabions provide flexible and environmentally friendly solutions for retaining walls, erosion control, and landscaping.
What Are Rock Gabions?
Gabions are wire mesh baskets filled with rock, designed to form strong and permeable retaining structures. They adapt to ground movement, reduce water pressure, and can blend into natural surroundings. Typically built as either mass gravity walls (relying on the weight of rock to retain the earth) or as mechanically stabilised walls utilising earth anchors to hold the wall in place.
