Building Products for the Channel Islands

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.

Road Contracting
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.

Precast Concrete Products
We manufacture a range of dense, lightweight and high strength concrete blocks along with precast kerbs, edgings and paving products.

We are the principal importer of cement to the Channel Islands. The cement is transferred through our silo terminals that you see at the Ports in Jersey and Guernsey.
