Project Planning and Execution
Initial Assessment and Planning:
Comprehensive site surveys were conducted to understand the existing conditions and constraints.
A detailed project plan, including a Construction Phase Plan (CPP) and Risk Assessment and Method Statement (RAMS), was prepared to ensure compliance with health, safety, and environmental standards.
Site Preparation:
Establishment of safe working areas with adequate access for Geobear’s mobile injection units adjacent to the site.
The tunnel, an old Victorian adit with rough-hewn walls and difficult access, required careful planning to navigate its challenging conditions.
Injection Process:
A 12mm diameter injection tube was manually inserted into the void through pre-formed holes.
The Geobear self-contained injection unit, including the geopolymer material, pumped the multi-component liquid geopolymer material to the injection locations
The geopolymer expanded up to 30 times its volume, filling the void and ensuring structural integrity.
