What Is Hydraulic Bracing?
Simplicity, for complex excavations
Hydraulic bracing is a reusable excavation support system that combines modular components, hydraulic adjustability, rapid installation and minimal on-site fabrication. It gives you a flexible alternative to custom steel frames, welded bracing and tieback systems across a wide range of excavation sizes, geometries and site conditions.
- A hydraulic ram unit connected to extension beams with simple, high-strength pinned joints
- Adapts to rectangular, square or multi-sided excavations spanning up to 67 ft / 20 m (subject to site-specific engineering)
- Integrates directly with trench sheet, sheet pile and concrete pile wall systems
- Scales up with hydraulic struts or multi-tier frames for deeper or high-load applications
Why Hydraulic Bracing?
Faster. Safer. Simpler.
Faster
Components can be assembled, adjusted and removed without cutting, welding or modification on site.
Safer
All major components are pre-engineered and feature integral lifting points, allowing safer handling and reducing the risk of damage.
Simpler
Standardized components make it easy to assemble.
Key Features
Modular, reusable, quick-pin connected
Quick-pin structural connections allow fast assembly, installation and removal, so one system can accommodate a range of excavations.
01
Hydraulic Ram Assembly
Double-acting hydraulic rams provide controlled installation, preloading and precise adjustment for minor site deviations. An integral mechanical lock-off valve then secures the brace in position, supporting easy installation and removal.
02
Pinned Connections
Pinned connections enable rapid assembly and disassembly without extensive bolting or welding, while providing the capacity to withstand demanding load cases and reverse-bending forces.
03
Integrated Shear Stops
Extension beams include shear stops welded to the beam at 3 ft / 0.9 m spacing, allowing knee or corner braces to be installed at any location along the beam. Knee brace forces can also be taken directly into the connecting lugs at the end of the extension beam sections.
System Components
Six parts, one engineered system
A typical multi-level frame is built from these standard modular components.

Applications & configurations
Typical applications
A wide range of temporary excavation and heavy civil work, including:
- Deep excavations
- Basements and underground structures
- Cofferdams
- Utility installations
- Manholes and chambers
- Tank installations
- Infrastructure and transportation projects
- Large foundation excavations
- Excavations supported by sheet piles
- Soldier pile and lagging or beam-and-plate systems

- Concrete retaining walls
Common configurations
Arranged to suit excavation geometry and required capacity:
- Perimeter frames for square, rectangular or polygonal excavations
- Corner-braced frames for irregular or multi-sided excavations
- Cross-strutted where additional internal support is required
- Long-span bracing where minimizing internal obstructions is important
- Multiple-level bracing for deeper excavations
- Hybrid configurations combining perimeter braces, cross braces and additional structural members
- Continuous waler systems where modular components form a supported perimeter beam
infraMOD Engineering Support
Three phases, one coordinated team
Behind every project is a team of engineers and advisors bringing design, pre-construction, manufacturing and construction together, coordinated through three phases.
01
Discover
Establishes clarity across scope, budget, timeline and concept. Critical insights and evidence give you a foundation for informed decisions, often uncovering opportunities to save time and money.
02
Design / Engineering
Project management, design, constructability and logistics are integrated into one seamless plan. We work with your team on a solution that fits your site constraints and installation schedule.
03
Deliver
Project Delivery and Logistics teams, integrated from the outset, ensure a smooth transition from design to final delivery, avoiding the delays and cost overruns that traditionally come with translating design into product.
Why infraMOD?
Over 35 years of solutions driven support
For over 35 years, infraMOD has evolved through engineering expertise, advanced steel fabrication, and modular innovation.
Total package solutions
Bracing, shoring and anchoring under a single roof, so you avoid sourcing from and managing multiple suppliers.
Designed success
The infraMOD methodology and engineered design capabilities create a safer, faster and more cost-effective construction process.
Constructability first
We plan ahead for access, equipment compatibility and erection sequencing, backed by strong coordination and clear communication.
Modular solutions reduce risk
Off-site modular fabrication means lower injury risk on site, fewer weather delays and reduced work stoppage.
“They understood our problem and offered the right solution – that’s why we brought them in.”
