Size, Colour & Dust of 20mm Blue Slate explained?
Sizing: All our products are naturally mined and are processed at a sorting plant using equipment to sort materials in to specific size ranges, to see how this process works see our materials explained page for more information, mining process and sizing.
Colour: As all our products are naturally mined there can be slight variations in colour in batches, this is due to rock formation and seem lines within the rock formation and where the materials have been mined, please see our materials explained pages for more information on mining processes.
Dust: With all naturally mined products coming from the quarries there is a certain amount of dust within and on the materials when shipped out, this is either caused by the blasting or digging at the quarries.
The dust can be cleared by simply hosing the materials once laid or letting nature take it's course by letting the dust wash away over time with rain fall.
