In Canada, sand and gravel are generally non-hazardous. However, if treated or contaminated, they may require a Safety Data Sheet (SDS). Always check local regulations for the latest information.
Aggregates
Gravel
Widely utilized for creating durable foundations, roads, and landscaping projects due to its excellent drainage properties and structural versatility.
GRANULAR "A"
A mixture of sand and crushed / round stone. Particle sizes no larger than 1 inch. Granular A is a finishing material for driveways, roads, parking lots and walkways.
GRANULAR "B"
A mixture of sand and round stone. Particle sizes up to 4 inch. Granular B is a sub-base material, primarily used as a foundation for roads, parking lots and driveways.
Recycled GRANULAR "A"
Concrete and asphalt crushed to a Granular A or Granular B specification. Used on roads, driveways and parking lots.
Recycled GRANULAR "B"
Concrete and asphalt crushed to a Granular A or Granular B specification. Used on roads, driveways and parking lots.
Recycled ASPHALT
Similar to Granular A in size. Made entirely from reclaimed asphalt and processed with a crusher. Used on roads, driveways and parking lots.

Sand
A foundational construction material, plays a vital role in concrete mixing, bricklaying, and landscaping, owing to its granular composition and versatility in diverse building applications.
SANDFILL
As the name implies, used primarily as backfill. Not a screened or processed material. Size of particles varies but is generally fine in nature.
BEDDING SAND
Screened coarse sand with particle sizes up to 1/2 inch. Used under walkways, interlocking pavers, stones and as trench or pipe bedding.
BRICK SAND
Finely screened sand with particles no larger than 4 millimetres. Used as a mortar mix. Also works well in sandboxes and play areas.
CONCRETE SAND
A well blended sand with particles smaller than 3/16” that has been screened and washed. Silt content is under 3%. Used for making concrete/cement products.
FILTER MEDIA SAND
A coarse sand between 2-4.75mm that has been screened and washed. Often used in septic beds or areas that need to be free draining.

3-way blend
A mixture of black loam (70%), compost (20%) and topsoil (10%) screened to 1/2 inch. Use as an enrichment to blend with soil in vegetable gardens and flower beds.
DYED WOODCHIPS
Ground hardwood chips dyed black or natural cedar. Use as a ground cover in gardens or flower beds.
CEDAR BARK WOODCHIPS
Ground cedar bark used as a ground cover in gardens and flower beds.
Fill Management
Screening Survey
Screening in the aggregate industry involves separating material into 2 to 6 different sized products. This is done by passing the material through a vibrating screen box with multiple screens or meshes. As the material moves through the screens, smaller particles fall through while larger ones are retained. The separated material is collected on conveyors for stockpiling. These end products, ranging in size, are then utilized in various building and construction applications.
