It weighs around 1.6 tonnes per cubic metre. A bike trail 1.5 metres wide, 30 metres long at 40mm deep needs about 1.8 cubic metres, roughly 2.9 tonnes. Use our calculator for your own trail. That's under our 12 tonne minimum for a delivered load, so take a full load if you can use the extra, or collect it yourself from Hope Valley, where no minimum applies.
Yes, 12 tonnes on a delivered load. That covers all our gravels, quartz and basalt. We can go under that if you really need to, but the transport cost per tonne is a lot higher so we don't recommend it for a small job. There's no minimum if you collect it yourself from Hope Valley.
