Quarry Product Range
Although initially established primarily to supply aggregates to the factories within the Gryphonn group, the quantity and range of the materials produced quickly exceeded our initial parameters and today Gryphonn Quarries now supplies hundreds of different customers from Civil Engineering Contractors and the Construction Industry through to DIY builders and Soil Improvers.
The Trefil Quarry Complex is a self contained site handling all relevant material processing, loading and dispatch. To ensure the quality and availability of a full range of products Gryphonn continues to invest in the latest Crushing and Mobile plant. Products produced range from Clean Dust and single size Aggregates to Large Blockstone and Sub-bases.
Clean stone is produced in an extensive range of sizes, tailored to meet different applications from pipe bedding to a drainage stone.
Available in 2mm of 4mm sizes, and stored immediately off the conveyor belt directly into its relevant shed. Thus ensuring a dry dust.
