Deco (Decomposed Granite)

Deco Granite is a stable, natural-looking landscaping material commonly used for garden pathways, walking tracks, driveways, courtyards, outdoor entertaining areas, tree surrounds, and accessible pathways. Its deep brown colouring and natural gravelly appearance make it a great choice for Australian native gardens.

Yes, Deco Granite hardens into a stable surface when compacted and is a great alternative to concrete or pavers. Deco is also a step up from loose gravel if you prefer a more uniform surface.

To calculate how much Deco Granite you need for your project, measure the length and width of the area where the Deco will be placed.

Next, determine the desired depth of the Deco. Your required depth will vary depending on the project you are undertaking and the area you need to fill. As a general rule, a final compacted depth of 50–100mm is standard for most Deco applications. Be sure to take compaction into account if you're levelling a surface to match the height of another landscaping element.

Once you have your length, width, and depth measurements, you can use our cubic metre calculator above or calculate the volume manually using the following formula:

Volume = Length × Width × Height

Deco Granite and Blue Crusher Dust have similar properties and functions. However, Deco Granite is more commonly chosen for decorative purposes due to its natural brown colouring. It is a great option for decorative driveways, walkways, patios, and as a ground cover around fire pits.

Blue Crusher Dust is more commonly used as a compactable base material beneath pavers, artificial turf, and other hardscape projects, although it can also be used for decorative applications. Crusher Dust compacts harder and creates a firmer surface, while Deco provides a stable base with a small amount of natural flexibility.
