If what you are looking for is a premixed bag of aggregate (stone and sand) round here referred to as ballast I would not bother as the mixes and aggregates are very variable as the Paving Expert says €œthe sweepings off the yard floor€�. Ballast is OK where finish and quality is unimportant footings and post holes come to mind.

If this is for your path/drive then you want to be sure about the quality which means buying the aggregates separately and mixing them accurately by volume. The best coarse aggregate for concrete is angular limestone chips @ 20mm for general purpose concrete. If you require a finer mix go for 10mm of the same. Make sure the chippings are angular in other words not rounded like pebbles the stones then tend to €œlock€� together for a stronger result. For the fine aggregates use sharp sand not builders sand. Go to the paving expert website for what proportions of coarse and fine aggregates to use plus cement.
