Bulk construction aggregates FAQs
- What size aggregate is used for road construction?
-
The most common sizes of aggregates used for road construction and maintenance include:
- 125mm or below for foundation or capping layers
- 31.5mm or below for use in granular sub bases
Asphalt typically contains aggregates between 31.5mm and 6mm. Aggregates used in surface dressing (to extend the lifespan of the road carriageway) are usually between 4mm and 10mm.
- Which types of aggregates are used in building construction?
-
Aggregates used in building construction can be categorised into coarse and fine aggregates, or a mixture of both. These include aggregate materials such as:
- Crushed rock
- Sand and gravel
- Secondary recycled aggregates
As one of the UK’s largest suppliers of bulk construction aggregates, we produce and distribute a wide range of materials for use in cement, concrete, and precast concrete.
For more information on the different aggregates used in construction (including how they’re classified), please read our guide to construction aggregates.
- Which type of aggregate is used for building foundations?
-
Building foundations tend to be constructed from concrete made from coarse aggregates, like gravel and crushed stone. These materials provide strength and durability, as well as load-bearing capacity, to provide stable foundations with long lifespans.
- What is the best material to use for fill?
-
Sand and gravel are the most common aggregates used in fill materials.
- Sand is a highly compactable, porous fill material found in concrete bases, backfill, and areas with drainage problems.
- Thanks to its permeability, gravel is favoured for applications like driveways and drainage solutions.
At Heidelberg Materials, we supply a range of fill materials for use across a wide variety of construction applications. For advice on choosing the right material for your project, please speak to our technical team.
- Where can I buy bulk construction aggregate?
