Meaningful ESG progress comes from consistent action on the ground.

RTU Group (RTU and Colinwell) has published its FY25 Environmental, Social and Governance (ESG) Report, marking the first standalone report under our sustainability strategy, Our Plan for What Matters.

At RTU Group, ESG is how we manage risk, build trust, and create long-term value. It matters because it directly impacts our customers, partners and teams we work with every day.

The report highlights progress made throughout FY25 alongside clear priorities for continued improvement in 2026.

We recently completed a stunning installation of Zircon®Polished Concrete in Sorrento White for a project in Dublin and the results speak for themselves.

From concept to completion, our team worked closely with the client to ensure the perfect finish was achieved, delivering a clean, modern aesthetic that has completely transformed the space.

Here’s what Eoin had to say:
"From the initial enquiry right through to delivery and installation, the experience with RTU was excellent. The sales process was straightforward, and Colin and his team were helpful in guiding us to the right product for our project. Any issues or problems were quickly resolved to ensure delivery and laying went as planned. The polished Zircon® Sorrento White decorative concrete looks absolutely stunning, it’s transformed the space completely. We’re delighted with the finished result and wouldn’t hesitate to recommend RTU to anyone looking for a premium concrete flooring solution."

If you're considering a high-quality, design-led concrete flooring solution, get in touch with our team today.
