​We are a full-service producer and distributor of high-quality aggregate materials for all construction needs.

Aggregate piles

​​​​​​​Stone, sand and gravel are essential components in the building of our cities and towns and the transportation networks that connect them. These materials also play key roles in agriculture, landscaping and storm water management. At CBM, we provide top-quality aggregate materials for projects of every scope and size.

Working from strategically located quarries, pits, depots, and recycling centers in Ontario, we employ state-of-the-art equipment and cutting edge processes to produce high quality aggregates for a variety of uses.

CBM aggregate materials are available for a wide range of construction and industrial needs, functioning as:

  • Base materials for roadways, walkways, railroads, parking lots and airport runways
  • Raw materials for creation of ready-mixed concrete, asphalt, precast pipe, concrete blocks, cement, and other building components
  • Large rip rap sizes for bank/slope stabilization, erosion control, and shoreline armoring
  • Landscape materials, both functional and decorative
  •  Essentials in water filtration and purification systems
  • High calcium lime for agriculture
