Underground industrial structures are the backbone of many operations—whether storing, transferring, or processing critical materials. When these structures require inspection, repair, or modification, the challenges go far beyond the surface. Limited access, confined spaces, and operational downtime make underground work especially complex. That’s why having the right expertise, equipment, and safety mindset is essential.
Fortis has built a strong track record in delivering high-quality underground structural work for storage bins, loading flasks, and other related infrastructure. By combining detailed inspections, precise repairs, and expertly executed demolitions & installations, we help our clients maintain structural integrity, optimize performance, and extend the service life of critical assets.
What We Offer
Comprehensive Structural Inspection & Repair
Fortis performs thorough structural integrity assessments inside and out with Certified Welding Bureau (CWB) Level 2 W178 inspectors. Identifying deficiencies, weld failures, and damage, then executing repairs to meet or exceed engineering and industry standards. Quality control measures are integrated into every step, ensuring long-term reliability.
Efficient Liner Plate Installation
Using specialized material-handling equipment such as winches, monorail systems, and unique engineered lifting devices, we install and/or replace liner plates in hard-to-access locations with precision and minimal operational disruption. Fortis has a dedication to precise fitting, ensuring adherence to engineered specifications and quality.
Structural Repairs and Modifications
Fortis removes, repairs and replaces components such as horizontal truss covers, staircases, platforms and structural reinforcement steel in compliance with design specifications. Fortis’s work reinforces critical load-bearing structures through additional gussets and stiffeners as well as upsizing structural members, while staying within the constraints of working in a challenging environment.
Ore Flow System Modification & Installation
With the experience of the Fortis team, unique system improvements, such as ore flow retrofits that improve material flow and prevent hang-up of material, can be installed efficiently, which minimizes downtime and disruption to overall mine operations.
