Specifications

Our stone consists of 93% quartz and 7% polymer resins and are available in 20mm and 30mm thickness slabs.

At our factory in Hertfordshire, we have a rigorous quality control procedure in place which ensures that every slab is thoroughly inspected before it is despatched. We also invite clients to view the materials if they wish.
