A great St Patrick’s Day in London. A big shout out to Ger Hayes’s team for putting such a huge effort into making this a special day for the children (either participating or spectating). Well done Larry O Leary for being the energy behind the parade. 👏🏻👏🏻

With St. Patrick’s Day celebrations upon us, we would like to wish all our staff, supply chain and Irish diaspora across the UK and Europe a safe and enjoyable weekend. We look forward to participating in St Patrick’s Day parades and events over the coming days in Malmo and London.

Some photos from our Low Carbon Demonstrator Event. It was a fantastic afternoon, I thoroughly enjoyed meeting everyone and having the opportunity to address the event. This is an exciting time for low-carbon concrete, and I believe we are on the cusp of making significant strides forward.    Concrete is one of the largest contributors to global CO2 emissions. Over 20 years ago, I was conducting post-graduate research at Trinity College Dublin, on concrete rheology—the science of the flow of concrete. Back then, it was a conversation killer when anyone asked what I did! 😄    Fast forward to today, at Sisk, we have been committed to reducing carbon in our projects for many years. One of our key initiatives was the creation of an internal Low Carbon Concrete Working Group. Last week, we gathered with industry colleagues to celebrate the completion of our low-carbon demonstrator at Wembley, a tremendous leap forward in this endeavour.     We have produced a demonstrator building using the world’s most versatile building material while cutting approximately 70% of its embodied carbon. This innovation reduces our carbon footprint and sets a new standard for environmentally responsible construction practices.    The Innovate UK funding opportunity emerged in 2024 was a perfect fit for our strategy, focusing on innovation and collaboration. By building demonstrators from new materials, we can explore and learn from these experiences. This approach not only builds confidence within the industry but also allows our design teams and customers to envision a sustainable future.    In the past, innovation in construction was often kept secret. But this initiative truly embraces collaboration. We have seen first-hand that when we collaborate, we can achieve so much more. The potential reductions in global emissions brought by these new technologies offer substantial benefits. Each consortium partner has played a crucial role in bringing this initiative to life, and it’s through this combined expertise that we are able to push the boundaries of sustainable construction.    FYI, if anyone is wondering why I've included a photo of me in a white coat holding a weird contraption... Its a mock-up of a handheld rheology tool that I researched for three years. Made out of materials found in the skip, a 4" drainage pipe and some broom handles. I gave it a lick of paint, took this snazzy photo, and made a pitch booklet to seek funding for my research. As a young entrepreneur, I thought I could make millions out of my invention! 😄 If only Dragons' Den existed back then. I learned a lot, moved away from research, but never lost my passion for concrete. Ecocem Global John Reddy Capital Concrete Ltd Jack.

Trials of Ecocem’s low-carbon cement technology, ACT, have been successfully completed at Wembley Park, London, as part of a demonstrator project funded by Innovate UK 👏   The project, led by John Sisk & Son Ltd with a consortium including Ramboll, Loughborough University, Creagh Concrete, Capital Concrete Ltd, and BRE, collaborated on this pioneering, scalable, low-carbon demonstrator, marking the world-first application of Ecocem's ACT technology in the UK, with initial test results showing over 70% carbon savings compared to traditional concrete.     🏗️ The two-storey demonstrator project used a range of different construction methodologies and concrete mixes all created using ACT. The structure contained all elements of a typical building including floors, stairs, columns and walls. In each case, the concrete made with ACT met the design specification for each application.     🏗️ ACT is globally scalable; it can be produced at almost all existing cement plants without significant investments or modifications and does not require major changes in construction practices. ACT requires little additional cost for cement plants to produce and no changes to existing cement plant work practices.    🏗️ If adapted widely, ACT can halve the amount CO2 associated with cement production - automatically saving approximately 50% of emissions or nearly a billion tonnes of global CO2 emissions.   #LowCarbonCement #Cleantech #Innovation #Construction #LowCarbon | John Reddy | Innovate UK Contracts for Innovation | UK Research and Innovation | Barry Ryan | Sarah-Jane Pisciotti | Aidan King | Maria Estrada

Initial results demonstrate over 70 percent of carbon savings compared to standard concrete. The low-carbon demonstrator project received £500,000 from Innovate UK funding as part of its 'Contracts for Innovation' to pioneer the use of ACT, Ecocem UK’s low-carbon concrete technology in a structure, which is the first of its kind. We gathered last week with our consortium partners for an event hosted at Wembley Park to discuss its findings. #WeAreSisk #Innovation #NetZero #Concrete Ross Cullen Maria Estrada Aidan King Juan A.

As International Women’s Day approaches tomorrow, I would like to take the opportunity to recognise all my female colleagues John Sisk & Son Ltd, many of whom who are attending the Construction Industry Federation (CIF) - IWD event in Ireland today. We are proud of the influence and change you are driving in our industry and in our business, thank you. As CEO of Sisk over the past the three years, I’ve had to take a real hard look at the business and challenged myself to identify how we can attract more females into the business. We have plenty of females working across Sisk in both operational and support functions, who have progressed to senior leadership roles over the past 12 months, each on their own merit. Creating an inclusive workplace where people can bring their true selves to work, without fear of prejudice forms a key part of our People & Culture strategic priority. Inclusive policies have become a hot topic, but we’re not shying away. We are steadfast in our commitment to creating an inclusive workplace and we take pride in attracting and retaining diverse talent. It makes great business sense, driving improved productivity, wellbeing and just general business performance. Our values at Sisk are Care, Integrity and Excellence and they underpin our approach to EDI and Inclusivity. Over the past 12 months, we have made some significant strides in the EDI space, most notably being recognised as Investors in Diversity Gold by the Irish Centre for Diversity. I am proud of the fact that Sisk is one of only 23 organisations in Ireland to be recognised with Gold accreditation and it is a testament to our ongoing commitment to fostering an inclusive and diverse workplace. It has been a collective effort to achieve this by our HR teams, employee resource groups, board member sponsors and all of our staff. Over 20 percent of our staff are now females, but we want this to keep growing. While we are on a positive trajectory, there is no silver bullet, as a business we must do more to attract more females into the business and we must celebrate all of your successes. #WeAreSisk #InternationalWomensDay #IWD2025 Sean Fitzpatrick Maura O'Farrell - Toles Steven McGee Donal McCarthy Marcus C.
