Quick answer

20mm Recycled Concrete is a sustainable recycled aggregate with a blue-grey tone. It withstands weather and foot traffic and is superior for drainage, so it suits a base for pavers or garden beds, driveways, paths, patios, garden features and concrete mixes. Lay about 50–75mm deep and compact for a firmer surface.

Eco-friendly

Crafted from premium recycled concrete, this is an eco-friendly alternative to traditional materials, reducing waste and conserving natural resources. Despite being recycled, the material still offers long-lasting strength and is resilient to weather and heavy use. Opting for recycled materials means you’re participating in a closed environmental loop, so this is an ideal choice for the planet-conscious landscaper.

Step by step

How to use 20mm Recycled Concrete

  1. 01Before laying the aggregate, ensure the surface is clean and level. For pathways or driveways, consider digging out a base layer of soil or existing material to create the desired depth.
  2. 02Spread the aggregate evenly across the surface, using a rake or shovel to distribute it. For a firmer surface, compact the material using a mechanical plate compactor.
  3. 03If using it as a base for pavers or garden features, lay the aggregate evenly, then add your pavers or features on top.
  4. 04For decorative uses, such as around garden beds or as a feature in landscaping, ensure the aggregate is spread evenly and level.

Common questions about 20mm Recycled Concrete

Is 20mm recycled concrete the same as blue metal?

No. It is crushed recycled concrete rather than quarried rock, so it is lighter in colour and weight and usually cheaper. Blue metal is harder and more uniform. Our blue metal vs recycled concrete guide compares them side by side.

Can 20mm recycled concrete be used for a driveway?

Yes. Spread it evenly and compact it with a plate compactor for a firmer surface.

How much 20mm recycled concrete do I need?

One cubic metre covers about 13–20 m² at 50–75mm deep.
