Research & Development

We work closely with manufacturers in our industry across all sectors testing new products, equipment and technology to continually develop and find new solutions.

By leading from the front, we not only provide our clients with clever design and tailored solutions, we also help them reach new standards in sustainability and waste reduction as well as cost savings.

Our broad experience has provided us with great insights, unrivalled supply chain partnerships and the R&D instinct required to advise our clients, many of whom are also defining and redefining the built environment.

Continued innovation led to the opening of Errigal’s dedicated Research & Development (R&D) Centre that provides bespoke manufacturing helping us to meet the requirements of our often challenging projects.

We value our clients and they value our continued focus on R&D as part of their long-term relationship with us, entrusting us to deliver solutions to their most critical construction challenges.
