Announcing:
Blubber Bay Quarry's aggregate grade rock is prized for its 100% fractured face and durability due to the magnesium content. The Blubber Bay Quarry aggregates have enjoyed success in projects such as the second runway at the Vancouver international airport as concrete aggregate and densification stone columns.

| 1. PETROGRAPHIC EXAMINATION - LIMESTONE dark grey, massive, uniform limestone with up to 10% white hair-line vein lets and small (<1mm) subhedral crystalline masses of calcite. Fracturing was angular to conchoidal. Some abrasion of the fracture surfaces had occurred during crushing and or transport. Several gave a strong reaction w/10%H.C.L. |
