Gravel driveway - what type and how much of it..

[danp]

Just moved house and the new driveway is rather mucky, doesn't look like it's been had any gravel on it for a while...

I've just looking at either pea shingle (10mm) or the bigger stuff (20mm)... suspect 20mm is better as:

- more likely to stay put
- won't get stuck so easily in tyres/shoes
- leaf blower/sucker won't affect it so much (there are lots of trees surrounding)

I have calculated the area at around 300sq/m

Don't want it to look like a beach/have big ruts where the cars plough through.

A quick google indicates should be around 5-6cm deep (which seems too deep to me - but that was a gravel shop!)

I'd reckon on an inch and a bit?

So how much do I need? (I have a number but would quite like some second opinions!)

(Wickes/local supplier do 850Kg bags for around £45)

Thanks, Dan

PS I'll probably stick with gravel as it would be a big job to put in tarmac/something else, and not sure it would suit the situation as much.

PPS No there is no membrane underneath, a "friend" did suggest I scrape up the existing gravel and put one down first, but I don't fancy that ;-)

Thanks for the replies.. so sounds like I want:

- 20mm gravel
- angular
- an inch and a bit deep... lets say 3cm
- to ring round a few suppliers (£20 a tonne is well under half of Wickes)

So does 16 tonnes sound about right?

Think I'll have a gravel spreading party, bring your own rake.
