Hi group,

Advice please on concreting.

I will be replacing my driveway and area around the house with
concrete.
It is currently a mixture of road plainings and concrete slaps.
The road plainings are a real pain and seem to trap dirt which gets
moved about
so it is all coming up.
This is a farmhouse and heavy machinery moves around on it.
7 ton jcb, 2 ton fork lift with load. It also will have to deal with a
tanker lorry
deliverying bulk LPG. So it will have to handle Weight.

Currently the concrete that was put on by the previous owner is simply
not up to
the job and has cracked and given way.

1. What base should I use? How deep and what materials.
2. What mix of concrete and what depth of concrete.

Ideally I'd like to use white concrete rather than dull gray unless
anyone can
think of other finishes. A smooth finish is required. No patterned
stuff as I
move a pallet truck around on this.
