Specialty Aggregates

​Specialty aggregates encompass a diverse range of sand, gravel, and crushed stone materials that possess specific properties tailored for unique applications. Unlike standard aggregates used in general construction, specialty aggregates are selected and processed to meet particular performance criteria, aesthetic considerations, or functional requirements.​

Construction and Infrastructure

Specialty aggregates are integral in producing high-performance concrete tailored for Alberta’s diverse climate, ensuring durability in structures like bridges, tunnels, and multistory buildings.​

Transportation

High-friction aggregates are employed in road construction to enhance traction, particularly in areas prone to icy conditions, thereby improving vehicular safety.​

Landscaping and
Architectural Design

Decorative aggregates are widely used to enhance the appearance of residential spaces, patios, and walkways. Specialty options, including coloured and fiber-reinforced aggregates, provide added visual appeal and durability, other enhancements like exposed concrete allow existing surfaces to be refreshed with modern, textured finishes that complement Alberta urban aesthetics.

Industrial Applications

Heavyweight aggregates support a range of industrial and energy-sector applications, including oil and gas infrastructure. Select materials, such as radon rock, are used where specialized performance is required. Our aggregate heating systems enable reliable cold-weather concrete pours, ensuring year-round operational continuity.

We offer a wide range of crushed aggregate products tailored for residential, commercial, and industrial applications. Our aggregates are available in multiple sizes and customizable blends, making them ideal for driveways, access roads, construction base layers, and load-bearing surfaces.

pavers, walkways, and utilities.
