Overcoming Bedrock, Rip Rap, and Water: ARMA Fence at Caribou Falls
Product Used: ARMA Fence
Location: Caribou Falls, Ontario.
The Challenge
The Caribou Falls project required securing a 300-foot section of critical infrastructure in one of Northwestern Ontario’s more demanding environments. Located adjacent to a hydroelectric generating station, the site introduced a combination of terrain, safety, and accessibility challenges that ruled out conventional fencing approaches.
This project presented a unique combination of environmental and structural challenges:
- A significant portion of the installation had to be completed on existing concrete walls and exposed bedrock, requiring precise anchoring and drilling methods to ensure long-term stability.
- Beyond that, sections of the fence line ran across a berm capped with rip rap, creating an uneven and shifting surface that complicated post placement and alignment.
- Adding to the complexity, the installation took place near fast-moving water from the station’s tail race, where safety, timing, and execution were critical.
- The remote location further limited equipment access and required careful logistical planning to transport materials and complete the installation efficiently.
- Finally, the fence system needed to follow the natural contours of the terrain—not only for visual consistency, but to eliminate potential security gaps across elevation changes and irregular ground conditions.
In many areas, posts could not penetrate the ground more than six inches, making traditional fencing installation methods impractical.
Additionally, the fencing system needed to follow the natural grade of the landscape, which included varying slopes and elevation changes.
Conventional chain link fencing would have required:
- Deep post driving
- Extensive site preparation
- Concrete foundations
- Terrain modification
These methods would have increased cost, extended installation time, and potentially disrupted the surrounding environment.
The Solution: ARMA Fence System
ARMA Gate Inc. team approached the project with a focus on adaptability, durability, and precision installation.
To address the varying surfaces, our team implemented specialized anchoring techniques designed for both concrete and bedrock applications. This ensured each post achieved maximum holding strength, regardless of the underlying material. In areas with rip rap, the installation strategy was adjusted to stabilize post placement and maintain structural integrity across uneven ground.
Given the proximity to fast-moving water, strict safety protocols were followed throughout the installation process. Our team coordinated work sequences to minimize exposure risk while maintaining project timelines, demonstrating the ability to operate effectively in high-risk environments.
To maintain continuous security, the fence system was carefully installed to track the natural grade of the landscape, adapting to elevation changes without compromising strength or alignment. This level of precision ensured a consistent barrier across the entire 300-foot span.
Despite the site’s remote location, the ARMA Gate Inc. team coordinated material delivery, crew access, and installation sequencing to complete the project efficiently, without delays or compromises in quality.
The Result
The completed installation delivers a robust and reliable perimeter security solution tailored to the site’s unique challenges.
By successfully integrating with concrete, bedrock, and rip rap surfaces, the ARMA Fence system provides long-term structural performance in an environment where failure is not an option. The fence follows the terrain seamlessly, eliminating gaps and reinforcing the overall security of the site.
The client now benefits from a low-maintenance, high-durability fencing system designed to withstand harsh weather conditions and demanding industrial use. Equally important, the installation was completed safely and efficiently, even in close proximity to hazardous water flow and within a remote setting.
Key Takeaway
The Caribou Falls project highlights ARMA Fence’s ability to deliver in complex, real-world conditions. Through a combination of technical expertise, field adaptability, and a commitment to quality workmanship, ARMA Gate provides solutions that perform where standard systems fall short.
In environments where terrain, safety, and reliability intersect, ARMA Gate Inc. delivers confidence on every install.

Securing 1.5 Kilometers of Aqueduct Without Ground Penetration
Product Used: ARMA Fence
Location: Kakabeka Falls, Ontario.
The Challenge: Securing Infrastructure on Sensitive Terrain
A utility operator needed to secure approximately 1.5 kilometres (5,000 feet) of aqueduct running alongside a public roadway.
The primary goal was to prevent unauthorized access, particularly snowmobilers during winter months who could potentially travel along or on top of the aqueduct structure.
While the need for perimeter protection was clear, the project presented several significant constraints.
The terrain surrounding the aqueduct was:
- Sloped, angle and uneven
- Environmentally sensitive
- Subject to strict ground penetration restrictions
In many areas, posts could not penetrate the ground more than six inches, making traditional fencing installation methods impractical.
Additionally, the fencing system needed to follow the natural grade of the landscape, which included varying slopes and elevation changes.
Conventional chain link fencing would have required:
- Deep post driving
- Extensive site preparation
- Concrete foundations
- Terrain modification
These methods would have increased cost, extended installation time, and potentially disrupted the surrounding environment.
The Solution: ARMA Fence System
The project team selected ARMA Fence because it was specifically engineered for challenging environments where traditional fencing systems cannot be installed.
Unlike conventional fencing that depends on deep post installation, ARMA Fence features a floating modular design that allows the system to sit above ground while maintaining structural integrity.
This provided several critical advantages for the project:
- Minimal ground penetration (less than six inches where required)
- Ability to follow uneven terrain without major site modification
- Articulation capability of up to 50 degrees to match grade changes
- Modular scalability for long infrastructure runs
Because the system is modular, installation could progress efficiently across the entire 1.5 km length of the aqueduct, adapting to the natural contours of the terrain rather than forcing the terrain to adapt to the fence.
Installation Advantages
The ARMA Fence system allowed installers to work with the terrain rather than against it.
Instead of drilling, excavating, or pouring concrete foundations, the modular fence sections were positioned along the route and secured with minimal site disturbance.
The system’s articulation allowed it to maintain consistent contact with the ground even as the slope changed. This dramatically reduced:
- Installation complexity
- Environmental impact
- Project costs
- Construction timelines
The result was a secure perimeter solution that respected both the infrastructure requirements and the surrounding environment.
The Result: Secure Infrastructure with Minimal Environmental Impact
With the ARMA Fence installed, the aqueduct is now protected by a durable perimeter barrier designed specifically for the terrain.
The project successfully delivered:
- 5,000 feet of secured infrastructure
- Effective deterrence against unauthorized access
- Minimal environmental disruption
- A long-term, adaptable fencing solution
Most importantly, the ARMA Fence allowed the project to proceed without the costly terrain modifications that traditional fencing systems would have required.
Key Takeaway
Protecting critical infrastructure does not always require heavy excavation or disruptive construction.
By using the ARMA Fence modular floating system, this aqueduct project achieved long-distance perimeter security while preserving the surrounding environment.
In locations where traditional fencing cannot be installed, ARMA Fence provides a reliable solution engineered for real-world terrain.
