Normally mm of type 1 hardcore will be enough as a sub-base as long as its wackered or vibration rollered to compact it.

A couple of months after I am HI, we have hired a company to block pave our driveway, which was half concrete and half garden, today the contractor dug up all Is it really a better option or just a cop-out for contractors lacking the skills to construct a sound sub-base? An urban myth is gaining currency within the residential block paving installation trade.
There is a growing trend for supposedly professional contractors to claim that a concrete sub-base is a better option than a traditional unbound granular aggregate sub-base. It should be apparent that a concrete base must cost more than an unbound sub-base.
A flexible sub-base consists of granular aggregates , while a concrete base comprises granular aggregates bound together with a cement. Roughly speaking, aggregate costs around 25 quid per tonne while cement is closer to quid per tonne. So, the key question: why is the contractor recommending a technique that is more expensive than that normally recommended? Is it sound advice or is there a distinct whiff of bovine excrement?
It is widely accepted that, for a typical residential driveway, a traditional granular unbound sub-base, when correctly installed , is more than adequate. On sites where there are problems with the sub-grade , such as boggy or made-up ground, running sand, etc. The key phrase in the preceding paragraph is that bit about being 'correctly installed'. When a driveway has ruts, or when it has humps and hollows, it's usually a safe bet that the sub-base isn't up to the job, and that is often due to the fact that far too many installers have little or no genuine understanding of how to correctly construct a sub-base, and so, to cover-up for their appalling lack of skill, they resort to using a concrete base, effectively over-engineering because they lack the competence to build a very basic pavement layer.
The most commonly encountered reasons for failed sub-bases beneath residential block paved driveways are:. Insufficient depth usually results from a combination of can't-be-arsedness and penny-pinching. The contractor decides not to dig to an adequate depth because it's too much trouble and the client probably wouldn't know any better, and every 20mm cut from the dig depth is 20mm less cart away and 20mm less aggregate to buy in.
