Hi All

I'm going to lay some 450 x 450 concrete slabs on the edge of my drive and I
know they will eventually be driven on by wife & daughters - despite dire
warnings not too.

So, I plan to put in 6" deep footings, 4" of hardcore & 2" of concrete, then
lay the slabs on a solid bed of mortar - about 3/4" thick.

Is that going to be strong enough, or do I need to keep digging?

Do they still advise 'hardcore' in such things (I don't think they do
in 'footings' etc)?

I know a local guy who just added a 3rd 'pad' to his front hard
standing (to add a van beside the two cars) and I noted:

1) It was dug fairly shallow
2) They put hardcore in in places
3) There was an iron gate in one bit
??

All the best ..

Depends on weight of wife and how many daughters.
If in doubt - keep digging and increase the concrete thickness !!

Get strong thick slabs, not cheepie B&Q ones, you may have 1/2 a
chance.

That will easily be enough. I toshed some 2" thick 600x600 conc slabs on mud as a temporary (2 years ago!) measure to park a car and they had only settled minimally and no cracks - surprised me!! Your build up will be well adequate.
