10 to 20 mm Gravel
10-20mm gravel is a versatile aggregate, making it one of our most popular products.
applications & uses
10-20mm gravel is a versatile aggregate that can be used for hard standing, drainage, pipe bedding and concrete production.
Our gravel meets the Series 500 Specification for Highway Works. This standard is pertinent for materials that are intended to be used for drainage or service ducts.

How do we separate and produce our 10-20mm gravel?
- Step One:
Construction and demolition waste is fed into our recycling plant.
- Step Two:
Oversized materials (anything larger than 100mm) are removed.
- Step Three:
Any remaining metals are removed using a large magnet.
- Step Four:
At this point, the aggregates and sand are separated. The sand is diverted to the sand plant to be processed and the aggregate continues through to the aggregates processor.
- Step Five:
As it goes through the aggregates processor, it is thoroughly scrubbed and cleaned by the log washer.
- Step Six:
The last step is to group the aggregates by size. This is done by screening the aggregates through a variety of sieves to create a 4-10mm, 10-20mm and 20-40mm product. The recycled aggregates are then delivered via conveyor belt to their respective stockpiles.
Where does it come from?
10-20mm gravel can be found in the construction and demolition waste that is recycled on our site. By using a circular business model we are able to recover and regenerate waste, minimizing the impact it has on the environment. We maximise the value from the aggregates by regenerating them, keeping them in circulation for as long as possible. Virgin aggregates like sand are a finite resource but are core material for building. Choosing recycled aggregates reduces the demand for energy intensive virgin aggregates which benefits the environment. The linear take, make, dispose model isn’t sustainable and is having a detrimental effect on the environment.
