Our vision is a future where buildings are healthier, sustainable and built to last. We are driven to meet the complex needs of the industry with lime-based products that are accessible, efficient and consistent in performance, while meeting the needs of those working with the materials on the ground.

WHY CORNERSTONE
How we get it done

A diverse expert team
The right resource for the job, we have a wealth of knowledge, skills and experience, making us as comfortable behind a microscope as we are with a trowel. From sampling and analysing materials to designing custom products or on-site surveying, we can advise on solutions based on the most complex needs or the most practical of requirements.
Research and development
At the core of what we do are research and development. While lime has been used for centuries, we know the future lies in innovation and meeting the evolving needs of the industry. Working collaboratively with our team, clients, and suppliers helps us maximise performance, reduce complexity and improve workability for those on the tools.


On-site manufacturing
All our products are made in Britain and manufactured on-site at our own facilities, providing us with agility, shorter lead times and complete end-to-end control of the process. All products are manufactured under an ISO 9001:2015 Factory Production Control System. Our bags are colour and batch coded for easy identification on-site and palletised for ease of transport, storage and handling.
