ᐅ Construction of a driveway using gravel, crushed stone, and paving stones?

Created on: 19 Jul 2016 17:06

Hi everyone,

What is the recommended construction for the subbase of the driveway?
Our excavation contractor will be back soon with the excavator to install the utility lines. At the same time, he will level the driveway to the correct height.

His rough rule-of-thumb suggestion for driveable surfaces:

25–30 cm (10–12 inches) crushed stone
5 cm (2 inches) gravel
8 cm (3 inches) paving stones
----------
38–43 cm (15–17 inches) total build-up

His rough rule-of-thumb suggestion for pedestrian paths:

15 cm (6 inches) crushed stone
5 cm (2 inches) gravel
8 cm (3 inches) paving stones
----------
28 cm (11 inches) total build-up

The foundations for the carport are already in place and are significantly deeper. This buildup would only apply to the paved surfaces.

Does this seem reasonable?

Thanks and best regards,
Andreas

@Payday: that’s quite a foundation depth

@andimann: yes, the landscaping contractors are currently very busy. First meeting in November 2015, work carried out in July/August 2016. Have you made a decision now?

Best regards, Rina

Good choice.
I would go with 0/32 crushed stone.

Remember to compact it.

Logo with compaction. I just need to figure out how to handle the edging stones. They should actually be installed before I put in and compact the gravel, right?!

Best regards,

Andreas

We installed them afterward. So, where the curbstones are going, we dug out about one shovel width again. This can be done quite well with a hoe and shovel.

That should be fine for now. Paving can be done later, and here we install the curbstones afterwards as well.

Curbstones are used when paving. Definitely do not install them now. They only create trip hazards or can damage car tires, and the height usually won’t fit properly later anyway.
Gravel is always a good choice. Slightly slope it towards the front and the garage (if you have one) to allow for easy driving in, and that’s it. Absolutely do not use recycled material, as it is not permeable. Depending on what you plan to put on it later, that can be a disadvantage.
