Case Study: 300m Gabion Basket Retaining Wall Installation

We were contracted to deliver a substantial retaining solution using gabion baskets for a large-scale development project. The brief was to construct a 300-meter-long by 3-meter-high retaining wall, providing both structural stability and long-term durability.

Scope of Works

Our team managed the entire process from ground preparation to final installation. Key components of the build included:

  • Excavation and site preparation to establish a stable foundation
  • Installation of a high-quality Terram geotextile membrane to prevent soil migration and aid drainage
  • Placement and assembly of galvanised gabion baskets, double-tied for enhanced structural integrity
  • Backfilling with clean angular stone, ensuring efficient drainage and long-term wall stability

Challenges Overcome

The scale of the project required careful logistical planning and phased delivery of materials to ensure continuity of work. Variable ground conditions along the 300-meter stretch meant our team had to adapt foundation depths and base preparations accordingly to maintain consistency in wall height and stability.

Results

  • Successfully installed 300m of 3m high gabion retaining wall
  • Integrated drainage layer using Terram geotextile for long-term performance
  • Structurally sound and visually natural finish
  • Project delivered on time and within budget

Client Feedback

“The team delivered a flawless retaining solution. We were particularly impressed with their efficiency, communication, and attention to detail from start to finish.”

Materials Used

  • Gabion Baskets: Galvanised steel mesh
  • Geotextile: Terram 1000 (non-woven)
  • Backfill: Clean angular stone (75–100mm)

Conclusion

This project highlights our ability to deliver large-scale, technically demanding retaining solutions. The gabion basket wall now serves as a durable and low-maintenance structure, seamlessly blending into the surrounding landscape while ensuring long-term support and erosion control.
