Cornerstone

Industry-leading mortars, renders & plasters for every sector

Our vision is a future where buildings are healthier, more 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, all while meeting the needs of those working with the materials on the ground.

A one-size-fits-all approach is a fundamental issue in our industry. We believe in transparency, thrive in complexity and remain intentional in providing solutions that bring real value.

Our years of experience have earned us a reputation for quality, service and innovation. Our range of products is diverse to meet the unique needs of both contemporary and historic construction.

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.

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.

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.
