As one of the most natural and versatile materials found, crushed stone or angular rock is more commonly classified as construction aggregates – used as a binder in concrete, tarmac or asphalt concrete. Due its cost-effectiveness in a raw state, crushed stone is widely used in construction contributing to the economic growth of the economy.

Used in various industries as a basic raw material for construction purposes, crushed stone is available in different sizes using crushers, depending on the application in which it’s used. The demand for crushed stone goes hand-in-hand with the well-being of a nation’s construction industry.

Where crushed stone is used:

  • Mixed in with concrete or paving blocks to form sidewalks, pavements, roads or verandas.
  • Used as a binder in asphalt or tarmac to form driveways.
  • Septic systems or self-contained sewage systems.
  • Used for landscaping purposes around trees or drains.
  • Typically used in railroad or shoreline construction for protection against the elements.
