Quarried aggregates are made from materials created thousands of years ago which is extracted from the ground then crushed, screened and/or washed to produce the required grading.

There is a network of quarries throughout the UK producing various quarried aggregates to satisfy demand.

Geographical location may affect the type, appearance and grading of quarried aggregates on offer due to variations in regional geology. As a rule of thumb, quarried aggregates are more expensive than recycled aggregates but are generally more aesthetically pleasing.

Aggregates are a fundamental ingredient in the formulation of ready mixed concrete, asphalt and mortar. Accounting for approximately 60 – 75% of ready mixed concrete’s volume, the composition of aggregates directly affects concrete’s freshly mixed and hardened properties.

Concrete’s strength, resistance to water, heat resistance and even its finished appearance can all be influenced by aggregates.
