The Ronez operations supply the Channel Islands with aggregates, ready-mixed concrete, asphalt and precast concrete products. Operating out of St John’s Quarry in Jersey and Les Vardes Quarry and Vale Castle in Guernsey, we offer a full range of high-quality construction materials.
Quarrying activity on our sites can be traced back to 1869 serving the island’s needs for quarried stone. We have grown and developed and now produce precast materials, ready-mixed concrete, asphalt and undertake contracting services.
