Concrete Mix for Driveway/Path

[imroberts]

I have an existing concrete driveway which extends to a path round the back of the house. The corner of this has been missing since before I bought the house and it's also cracked as it's far too thin (and tapers away to nothing at the edge). I don't actually use this section of driveway other than to walk on, but I plan to cut it off neatly and relay a section to a decent depth.

I've used all-in-one ballast before for laying a base for a garden wall. Will this be fine for this job or are there benefits to buying separate gravel and sharp sand and mixing it myself? If I was to buy the separate bits, I notice that Wickes sell 10mm and 20mm gravel - which would I use and when would the other be used?

All in ballast will be fine. 10mm stone is a little easier to trowel and finish generally speaking and more suitable for shallower depth slabs such as 75/100mm.

Consider readymix or at least price it as often the cost of buying and getting materials delivered for small jobs can mean its almost the same as just buying readymix which is obviously miles less work.
