Size, Colour & Dust of Black Basalt 20mm explained?
Sizing: All products are naturally quarried and are processed at source via a screening process using equipment to sort materials in to specific size ranges.
Colour: As all our products are naturally quarried there can be colour variations as well as size variations dependent on the formation of the mineral in the quarry at any given time.
Dust: With all naturally quarried products there will always be an element of dust on all materials. The dust can be cleared by simply hosing the materials once laid or letting nature take its course by letting the dust wash away over time with rain fall. The images on our website are after they have been washed.
Please see our materials explained pages for more information on the quarrying and sizing process.
