Aggregates in the construction sector is a term used to describe stone which is crushed and screened into different sizes for different applications. An aggregate can be used to provide a solid base to construct roads and buildings spreading the load to the ground below or in mixtures to produce concrete or tarmac. They can also be used to aid drainage or in decorative applications where their appearance is important.

What Are They Produced From?

The first step is to consider the source material which can be either:

  1. Primary  – Stone which is usually blasted from the rock face for the purpose of producing the Aggregates.
  2. Secondary  – This is stone which is produced as a by-product of a process i.e. stone is extracted to produce slabs, slate tiles or architectural cladding etc. and the waste from these processes is crushed to produce Secondary Aggregates. This is environmentally and economically beneficial as this stone would otherwise be discarded in tips.
  3. Recycled –  Are produced from inert waste which is discarded during the excavation of roads or demolition of buildings and structures etc. This waste is processed through a facility permitted by the Environment Agency and under a protocol to turn the waste into a suitable Aggregate. Recycled Aggregates are a more sustainable alternative to Primary Aggregates. Recycled Aggregates are more commonly used for general hard standing, roads, tracks and as a sub-base.

At Burlington Aggregates we produce a full range of Aggregates from all three source materials from our primary and secondary quarries and through our regulated recycling facility. We have the capability not only to delivery locally but nationally.
