We consider ourselves privileged to work with a premium raw material and believe in honouring its pedigree through first-class processes and techniques to deliver a premium product range. We subject all of our processes to rigourous and regular quality control checks, from inspection of raw materials, through monitoring of the entire manufacturing process to final quality approval and guarantee of our end products. The quality system implemented by Kilkenny Limestone has been independently audited and verified.


Quarries from Kilkenny Limestone are ATG certified. ATG is the strictest and most respected auditing and assessment system for blue limestone. This certification guarantees Kilkenny Limestone’s adherence to a technical base specification, operation of a rigorous quality control system and submission of our stone to a process of independent and expert testing on a regular basis.


Our entire activity in the 3 sites has ISO 9001:2015 Certification. The production and sale of all our products – raw blocs, cut slabs, finished products – are managed in accordance with two principles: the satisfaction of our customers and the continuous improvement of our processes and our range of products.

CE Marking

We employ a system of CE marking to highlight the performance standards that are expected from our products. This also demonstrates our commitment to a high level of Health, Safety and Environmental Protection standards as required by European regulation.
