Granular Fill Materials
Roadstone Granular fill materials are produced at all quarry locations by means of blasting, crushing and in most cases screening into the required sizes. Roadstone Granular fill materials produced at our Pit locations are extracted by excavator and screened/crushed into the required sizes.
Description
Granular materials may vary in maximum size and particle size distribution (grading) to suit the required applications. When producing these fill materials, the aim is to always have a finished product which is clean, hard and durable and capable of performing as required in an engineering environment.
Production of granular materials is managed under our ISO 9001 Quality Management scheme with all locations having either System 2+ or 4 levels of attestation of conformity as appropriate.
