Canada’s mining sector generates over $100 billion in annual economic activity and operates in some of the most demanding environments on earth. From gold and silver mines in the Canadian Shield to oil sands operations in northern Alberta and potash operations in Saskatchewan, mining assets are subject to extreme chemical exposure, mechanical abuse, and temperature cycling that destroy conventional coatings within months.
Polyurea has emerged as the coating of choice for mine operators seeking durable, long-lasting solutions across dozens of application categories.
Secondary Containment
Environmental regulations require robust secondary containment systems at virtually every mining operation. Spills of process chemicals, diesel fuel, lubricants, and tailings slurry must be contained to protect groundwater and satisfy provincial and federal environmental requirements. These regulatory requirements are taken very seriously by mine operators who face significant fines and operational shutdowns for compliance failures.
Polyurea’s chemical resistance to a broad range of industrial chemicals and its ability to form seamless containment systems — even over complex geometries with sumps, drains, and penetrations — makes it ideal for secondary containment berms and pad coatings. Applications in this category typically specify 120-200 mil DFT systems with enhanced chemical resistance formulations.
Process Vessel and Tank Lining
Process vessels, settling tanks, heap leach pads, and tailings storage facilities all benefit from polyurea protection. Mine operators have found that properly selected and applied polyurea systems outlast conventional rubber or cementitious linings by a factor of two to three, reducing the operational disruption and cost of relining cycles.
The same principles apply in water infrastructure — see our guide on cistern lining best practices.
Truck Bed and Equipment Protection
Haul truck beds at mine sites experience some of the most extreme wear conditions imaginable. A polyurea truck bed liner applied at 125-250 mil significantly extends bed life and reduces maintenance frequency versus uncoated steel. The economics are compelling: a $5,000-8,000 liner application that extends a $500,000 haul truck’s bed from 18 months to 5+ years of service is an easy business case.
Infrastructure in Remote Locations
One of polyurea’s practical advantages in remote mining operations is the relatively compact footprint of application equipment compared to alternatives. A skilled CPCA-certified applicator team with a properly equipped service truck can fly materials and equipment into remote sites and complete significant work with minimal infrastructure. The fast cure time means minimal production interruption — many polyurea repairs can be done during scheduled maintenance windows.
Our featured member Northern Shield Coatings has built a strong business model around exactly this type of remote, demanding work.
