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.
Crushed rock aggregates produced at the Ronez quarries are supplied direct to the local construction industry, as well as forming the basis for an extensive range of construction products including ready mixed concrete, asphalt and concrete products.
Ready Mixed Concrete
Our ready mixed concrete plants in Jersey and Guernsey supply a range of products from floor screeds to designed mixes for structural applications.
We are able to provide a wide range of asphalt products from base course to specially designed mixes in accordance with the British / European standards.
The road contracts department in Guernsey and Pallot Tarmac Ltd in Jersey, serve the surfacing, trench reinstatement and contracting needs of the Islands roads and infrastructures.
