Driveway tarmac specs?

The block was the cheapest out of the range we were shown. The extra was because they would have to use digging machinery to get deeper into the compacted chalk, with tarmac they would just remove the loose stones.
The driveway is share by four of us and is in front of a row of four garages.

The cheapest block may be fine provided it is suitable, and the right depth. There are some I would not recommend, and in your case for multi garages you would be wise choosing 80mm deep.

The comment about extra digging for tarmac is nonsense - they all require digging.

You know the contractor and the specification for the job. I do not know either, but it sounds like a typical approach to push you towards a bish bosh tarmac job. In essence, make the tarmac the cheapest quote, cover the ground with some black stuff and the consumer will be non the wiser.
