Sustainability

Nationwide aggregates delivery by road, rail and water

As aggregate suppliers, we deliver construction aggregates around the nation using an integrated logistics network across road, rail and water.

Road Road

Our core road fleet consists of 1,200 liveried trucks, primarily operated by self-employed owner-drivers under a structured franchise scheme to ensure reliable and flexible bulk aggregate delivery.

Rail Rail

We’re among the UK’s largest users of rail freight for aggregates, transporting over 2.5 million tonnes of material annually. Aggregates are moved from seven rail-connected loading points to 12 regional distribution depots using a dedicated fleet of locomotives and wagons.

Water Water

In addition, we use barge transport to supply production facilities located along the River Thames, supporting sustainable and efficient marine aggregate distribution.

Aggregates FAQs

What are aggregates, and how are they made?

Aggregates are materials that have been crushed into different sizes for use across the construction sector.

If they are extracted from quarries and pits, they’re known as primary aggregates. If they’ve been manufactured or are a by-product of an industrial process (e.g. blast furnace slag), they’re classed as secondary aggregates. Materials that have been repurposed from construction or demolition waste into aggregates are also secondary aggregates, known as recycled aggregates.

In all cases, the materials are crushed into smaller pieces and then screened into different sizes and qualities to ensure they’re suitable for a range of applications. Some aggregates undergo an extra step: washing. This removes impurities to make sure the aggregate has the desired qualities and performance levels for use.

What are the different types of aggregates?

Aggregates are classified as either ‘coarse’ or ‘fine’.

Coarse aggregates are produced from materials that have been crushed and screened to be greater than 4mm. They are typically 20mm or larger.

Fine aggregates are usually smaller than 4mm in diameter. They’re the smallest construction aggregate and include sand and crushed rock fines.

Heidelberg Materials Aggregates produces and distributes both coarse and fine aggregates, as well as other types. These include:

  • Crushed rock
  • Sand and gravel
  • Recycled aggregates

What are the four main types of aggregates?

The four main types of aggregate used in landscaping and construction are:

  1. Gravel
  2. Sand
  3. Crushed rock
  4. Concrete fill

They vary in material type and size, with each type of aggregate serving a unique purpose within specific applications.

What is Type 1 aggregate used for?

Commonly referred to as ‘MOT Type 1’, Type 1 aggregate is used as a base layer for pavements, roads, drives, trench fills, patios, and a range of other applications. Heidelberg Materials is one of the UK’s largest suppliers of bulk construction aggregates and supplies various sizes of aggregate for a range of core applications, including MOT Type 1 sub base.

How much aggregate do I need?

To understand how much aggregate you need for your project, please use our Aggregate Calculator.

Work out how much aggregate you need by measuring the length, width, and depth of your project area, then multiplying the numbers to find the volume (in cubic meters). Next, convert the volume into tonnes. To do this, multiply the volume by the aggregate's density - this is approximately 1.5 to 1.7 tonnes per cubic meter, but it’s best practice to ask your supplier.

What aggregates are used in concrete?

Concrete is manufactured from a blend of coarse and fine aggregates, water and cement.

Aggregates used in concrete consist of geological materials such as gravel, sand and crushed rock. Specific aggregates, or combinations of aggregates, are selected for their durability, strength, and ability to achieve specific project outcomes.

What size aggregate should I use for concrete?

The size of aggregate needed will depend on the application the concrete is being used for.

Concrete is produced from a blend of coarse and fine aggregates, cement and water. Typically, the coarse aggregate fraction will comprise of material between 4 and 20mm, either in the form of a single graded aggregate product or a blend of individual sizes supplied to the concrete mixing plant.

Certain applications, such as heavily reinforced structures, may require a smaller nominal sized material for ease of placement around the rebar.

Please contact our team for more guidance on the right size aggregate for your concrete application.

Where to buy aggregates?

You can buy aggregates for both commercial and domestic applications from a reputable aggregate supplier, like Heidelberg Materials. We produce and supply a variety of loose and bagged aggregates for use across the construction sector and home projects, including:

  • Type 1 aggregate
  • Crushed stone
  • Sand and gravel
