What Are Gravel & Crushed Rock Materials?
Gravel and crushed rock are versatile, high-strength aggregates used for everything from residential landscaping to heavy-duty road construction. Crushed rock is mechanically broken stone with angular edges that interlock for a stable base, while natural gravel is rounded and smoother, ideal for drainage and decorative applications. At North Bay Materials, our aggregates are sourced from trusted local quarries and screened for consistency, durability, and compaction strength.
