For the most part, our 20mm Ballast is a light, sandy brown colour scattered with differently coloured stones mixed in. Mostly consisting of sharp sand, our 20mm Ballast is mostly a product of 20mm stones which gradually become fine sand. As a result of this, the Ballast makes for a great material for creating smooth concrete mixtures, pipe beddings, building levelling and landscaping constructions.

The 20mm Ballast has been developed in the majority from naturally derived materials. This includes aggregates such as Shingle ranging from 6mm to 10mm in size, all mixed in with Sharp Sand. Because of this, we do not suggest you use 20mm Ballast in areas that you want to look visually appealing. We advise this because depending on where the Ballast is quarried from, the colours differ.
