How many tonnes is a cubic metre of General Purpose Road Base 20 mm?
General Purpose Road Base 20 mm weighs roughly 1.6 tonnes per cubic metre loose, so 5 m³ is about 8 tonnes. Moisture can make it heavier. The booking uses this weight to pick the right tipper.

What is the minimum order?
The minimum order is 1 cubic metre. For larger orders, the booking works out the number of loads and recommends the right tipper automatically.
When can it be delivered?
Choose today, tomorrow or a specific date, subject to availability, and pick a 2-hour window between 7am and 5pm.
Where will the truck tip it?
On your driveway or a firm, clear area of your site. Tell us about narrow gates, overhead wires, slopes or soft ground when you book. If it must be tipped on the road or nature strip, check your council's requirements first.
