Nambucca Stone (20-50mm) - Pre Bagged 20kg

Our Nambucca Stone (20–50mm) is supplied in easy-to-transport 20kg bags. They are packaged in a thick plastic that can hold the weight of the stones and is long-lasting if you need to store the bags before completing your project.

For a 20kg bag of Nambucca Stone (20–50mm), you will need approximately 70 bags to cover 1 cubic metre (1m³).

If you need help calculating your measurements, try the m³ calculators on our measurement guide or call our friendly team on (07) 3245 5677.

To calculate how many bags of Nambucca Stone (20-50mm), you'll need, first work out the volume of your project using the following formula:

Length (m) × Width (m) × Depth (m) = Cubic Metres (m³)

Once you have your cubic metre measurement, multiply it by 70 to estimate the number of 20kg bags required.

For example: 0.5m³ × 70 = 35 bags

This calculation is based on 20kg bags only.

As our Nambucca Stone (20–50mm) is a chunkier stone, we recommend laying it at a depth of 75–100mm for even coverage. Laying it too thinly may result in a patchy finish.

No. Nambucca Stone (20–50mm) is supplied by the manufacturer in bagged form only and is not available in bulk.

The supplier also does not send these stones out in bulk quantities, so your only option is to purchase them by the bag. If you need help calculating how many bags you need, check the FAQs above or call our friendly team on (07) 3245 5677.
