When Should You Consider Ground Freezing?
Ground freezing is particularly suitable for challenging ground conditions, high groundwater levels or complex structural geometries where conventional methods reach their limits. It provides a flexible solution for construction work in densely built-up urban areas, cross-passages between tunnel tubes, and connections between new and existing underground structures.
Typical Applications of Ground Freezing Include:
- Tunnel and specialist underground construction
- Shafts and excavations
- Launch and reception shafts
- Cross-passages and connecting structures
- Underpinning and complex structural connections
Whether ground freezing is technically and economically appropriate depends on factors such as ground conditions, groundwater levels, geometry, the required strength of the frozen soil body and the construction sequence.
Our Services
Every ground freezing project has its own requirements relating to ground conditions, groundwater and construction methods. That’s why we take a holistic approach to ground freezing:
- Planning and design of tunnel, excavation and shaft freezing systems
- Assessment and design of ground freezing solutions using methods such as brine and liquid nitrogen freezing, tailored to each project’s technical requirements and construction constraints
- Frozen-soil engineering, including finite-element method (FEM) calculations
- Determination of mechanical and thermal parameters in our ground freezing laboratory
- Construction support and monitoring during implementation
