Arduno® refers to a specific range of Erinstone® paving products that are treated in a tumbler to batter the sharp sawn edges and create a more natural looking hard surface that blends in perfectly with every garden. It’s relative small dimensions and thickness (5 cm) allows for joint less fixing in a bed of stabilized sand, similar to the fixing of concrete pavers. When fixed in a mortar bed, a large irregular joint renders a quite different effect. Arduno® paving offers an affordable alternative in authentic Irish Blue Limestone that is timeless and durable.
