Interspan Announces National Partnership with Hydra Capsule to Supply Flat Jacks Across Australia
Interspan is pleased to announce a new strategic partnership with Hydra Capsule, strengthening our capability to deliver smarter, safer and more efficient solutions for structure jacking, structural strengthening, and specialised civil engineering works.
This collaboration enhances our delivery capacity across Australia, ensuring clients benefit from high-quality flat jack systems, faster turnaround times, and the engineering expertise required for complex load-transfer and structural control operations.
Flat Jacks: Precision Load Transfer & Structural Control
Flat jacks play a critical role in many building and infrastructure applications, providing a compact, highly controlled method for:
- Load transfer
- Structural jacking
- Precision pre-loading
- Settlement correction
- Bearing replacement
- Heavy lifting in confined spaces
Interspan flat jacks deliver extremely high thrust forces in confined spaces, with capacities ranging from 8 to 1000 tonnes, which is ideal for both temporary and permanent works. All units are manufactured and tested to international standards to ensure safe and reliable performance.
Permanent flat jacks can be grouted in situ using cementitious grout or epoxy to provide a durable load path, while temporary units allow real-time monitoring using calibrated pressure transducers. This versatility makes them suitable for applications such as:
- Excavation strut pre-loading
- Load transfer onto new foundations
- Pre-loading of steelwork and bridge bearings
- Ground settlement compensation
Why This Partnership Matters
By aligning with Hydra Capsule, Interspan can now combine:
- High-quality flat jack systems
- Interspan’s specialist engineering expertise
- Improved national turnaround and supply responsiveness
From outrigger beam load transfer to bearing replacement and groundworks pre-loading, flat jacks remain essential tools for controlled, measurable and safe structural modifications. This partnership ensures our clients benefit from best-in-class systems, backed by Interspan’s proven capability in structural control and jacking operations.
We look forward to the value this collaboration with Hydra Capsule will bring to our clients, partners and projects across Australia.
