Where do I start?

You need to form the natural ground into a sub-base with a crown on it so as water can run off the driveway, not down the driveway

I don’t have enough natural ground for the sub-base

Consider building it up with a 100mm thick layer of either 40mm Class 3 or Class 4 Crushed Rock (in areas that are normally boggy consider using 100mm Crushed Rock)

What gravel do I dress the top with

For driveways on a sloping block select either a 20mm Class 4 for driveways predominantly used by passenger vehicles or a 40mm Class 4 Crushed Rock for driveways predominantly used by Trucks or Heavy Vehicles

For Driveways on a flat block select either a 20mm Class 3 Crushed Rock for driveways predominantly used by passenger vehicles or a 40mm Class 3 Crushed Rock for driveways predominantly used by Trucks or Heavy Vehicles

How do I spread the gravel

Our trucks can run the gravel out, however, you will still need either a grader, front end loader or bobcat to finish it off for you. It is best to spread it, then wet it down and then roll it to compact it for a better result and longer life.

How much do I need?

Work out the cubic metres then multiply it by 1.5 for loose tonnes volume or 2.4 for compacted tonnes volume.

How do I work out cubic metres?

Multiply length x width x depth. ie: 100m x 3m x 100mm is 100 x 3 x .1 = 30m3
30m3 x 1.5 = 45 tonnes of loose material
30m3 x 2.4 = 72 tonnes of fully compacted material
