A mixture of 20mm river gravel and sharp sand. 

Pre-blended for ease of use in concrete manufacturing, to be mixed with cement and water to correct ratio. With it being a heavy compound it promotes strength when made into concrete. 

The smaller stone makes it easier to level and smooth when the depth to be concreted is smaller than normal. 

Ballast 20mm is suitable for other building projects and can provide an even sub-base for driveways, shed bases and more.
