Think it's time we had the drive done (well it was one of the most
pressing jobs to be done when we moved in about 10 years ago).

Does anyone know of a resource which would provide comparative, ballpark
(per m^2) costs for different surfaces? I don't really want to start
getting contractors in for specific quotes until we've at least narrowed
it down to what type of surface we want.

Thinking about:
Tarmac
Block paving (concrete? clay?)
Pattern imprinted concrete
Cobbles (concrete? Clay?)
Probably others too.

Thanks
David
