Examples of volcanic rock (vesicular basalt and black pumice) applications include landscaping, barbecue rocks, construction backfill, lightweight aggregate, industrial fillers, anti-slip abrasive traction sand, all weather sports fields, horticultural and agricultural soil amendments, and soil-less growing mediums. We are a major supplier to the Vancouver construction industryand the block and masonry industry in Western Canada.
Examples of naturally calcined shale applications include lightweight concrete block aggregate, play field material, kitty litter, filtration medium, industrial fillers, pigments, industrial ceramics and pottery.
PROCESSING OPPORTUNITIES INCLUDE:
Volcanic aggregate has weight and fire rating advantages and as a natural pozzolan.
CONCRETE MASONRY UNITS
Volcanic aggregate is a more durable, lower cost, environmentally friendly alternative to commercially manufactured expanded clay aggregates.
PRE-CAST AND READY MIX APPLICATIONS
The low weight and high strength characteristics make volcanic aggregate a natural alternative to other concrete.
The aggregate’s inert and non-conductive characteristics are of special interest to this industry.
WATER FILTRATION SYSTEMS
Basalt and naturally calcined shale material are a natural adsorbent and filtration medium that are proven and work very well for water filtration in agriculture, household and industrial applications.
Tephralite™ from Quesnel has been used in many infrastructure projects in Vancouver BC and across Canada. Projects include the Golden Ears Bridge, the Pitt River Bridge, Canada Line Rapid Transit System, Port Royal Development and the new Douglas Border Crossing, to name a few.
