Project details



Project Goals

The client, a high-end residential estate,required a robustinfrastructure solution to mitigate the impact offlooding. The main objective was to construct a gabion wallthat could serve as a barrierto absorb and deflect the force of water,thereby protecting nearby structures and infrastructure from potential flood damage.


Project Overview

Client: Balgowan Estate, Sandton
Location: Sandton,Johannesburg, South Africa
Project Duration: 5 weeks
Completion Date: July 2023


Scope of Work

The project involved

  1. Site Analysis: Understanding the landscape and flood patterns.
  2. Design: Creating a customized gabion wall design to meet specific flood mitigation requirements.
  3. Construction: Building the gabion wall using high-quality materials to ensure longevity and effectiveness.
  4. Testing and Evaluation: Ensuring the wall met all safety and functionality criteria.


Site Analysis – We began by conducting an in-depth analysis of the site

  • Topographical surveys to understand the terrain.
  • Hydrological studies to predict waterflow and flood patterns.
  • Soiltesting to determine the bestfoundation for the gabion wall.

Construction – The construction phase involved

  • Foundation Work: Laying a stable base to supportthe gabion structure.
  • Gabion Assembly: Filling metal cages with stones and systematically placing them to form the wall.
  • Layering: Ensuring each layer was interlinked for structural integrity.
  • Drainage Solutions: Incorporating drainage systems to prevent water buildup behind the wall.

Quality Assurance and Testing

Once the wall was constructed,rigorous testing ensured the structure’s integrity:

  • Hydraulic Testing: Simulating flood conditions to test wall performance.
  • Structural Analysis: Checking for any weaknesses or faults.
  • Final Inspection: Ensuring that all design specifications and safety standards were met.



The completed gabion wall not only meets but exceeds the client’s expectations, providing a durable solution for flood mitigation. The wall blends into the natural landscape, enhancing both safety and aesthetic appeal at Balgowan Estate.
