40mm Sharp Sand & Gravel Mix [Ballast] is the standard aggregate for mixing concrete. Widely used in construction and domestic applications.
Please Note: The Ballast supplied will be that of your local material and thus appearance will vary. Not suitable for drainage due to high fines content.
Please note that the stones are measured at the narrowest point. The sizes used on the page therefore refer to the technical measurement. Because the gravel is measured at the narrowest point, the actual size may vary slightly.
