In an era where sustainability is paramount, industries across the board are seeking innovative solutions to reduce their environmental footprint. The construction sector, in particular, stands at a critical juncture where adopting eco-friendly practices is not just a choice but a necessity. At O’Reilly Precast, we’re proud to be at the forefront of this movement, championing sustainable solutions that prioritise the health of our planet without compromising on quality or efficiency.

  1. Reduced Carbon Emissions

One of the most significant environmental benefits of precast construction lies in its ability to minimise carbon emissions. Traditional construction methods often involve extensive on-site operations, leading to higher energy consumption and increased greenhouse gas emissions. However, precast concrete components are manufactured off-site in controlled environments, allowing for optimised energy usage and reduced emissions. By producing precast elements in a factory setting, we can significantly lower our carbon footprint, contributing to a cleaner, healthier environment.

  1. Resource Efficiency

Precast construction also offers notable advantages in terms of resource efficiency. Unlike traditional cast-in-place methods, which can result in material waste and excess usage of natural resources, precast manufacturing allows for precise measurement and optimisation of materials. This means less wastage of concrete, steel, and other resources, leading to both cost savings and environmental conservation. Additionally, the durability and longevity of precast concrete structures further enhance resource efficiency by reducing the need for frequent repairs or replacements.

  1. Enhanced Air Quality

The production of precast concrete components involves stringent quality control measures, including the use of eco-friendly additives and admixtures. These additives not only improve the strength and durability of the concrete but also contribute to better air quality by reducing the emission of harmful pollutants. As a result, precast construction not only minimises environmental impact during the manufacturing process but also helps create healthier indoor and outdoor environments for occupants and communities alike.

  1. Sustainable Design Opportunities

At O’Reilly Precast, we understand the significance of integrating sustainable design principles into each project. A fundamental aspect of our commitment involves integrating Ecocem GGBS (Ground Granulated Blastfurnace Slag) into our products. We incorporate up to 30% of Ecocem mix in our prestressed, precast concrete, and paving products. Ecocem GGBS serves as a high-performance substitute for traditional cement, enhancing both technical performance and aesthetics while significantly reducing our carbon footprint. Through close collaboration with clients and partners, we aim to deliver tailored precast solutions that not only fulfill aesthetic and functional requirements but also align with sustainability objectives.

  1. Long-Term Environmental Benefits

Perhaps the most compelling aspect of precast construction is its long-term environmental benefits. Unlike temporary solutions or quick fixes, precast concrete structures are built to last, withstanding the test of time and environmental wear. By investing in precast construction today, we’re not just addressing immediate environmental concerns but also laying the foundation for a more sustainable future for generations to come.

In conclusion, the environmental benefits of precast construction are undeniable. From reducing carbon emissions and resource consumption to improving air quality and enabling sustainable design, precast concrete offers a holistic solution to the challenges facing the construction industry. At O’Reilly Precast, we’re committed to driving positive change through innovation, collaboration, and a steadfast dedication to sustainability. Together, let’s build a greener, more resilient world, one precast structure at a time.

In a recent development, Minister for Finance Michael McGrath has announced a significant amendment to the Defective Concrete Products Levy, which has garnered much attention since its introduction as part of Budget 2023. This amendment is set to have a positive impact on the precast concrete industry, and O’Reilly Concrete is pleased to share this important news with our customers.

Concrete Products Levy Background

The Defective Concrete Products Levy was initially introduced in October 2022, as part of a broader initiative to fund the Mica Redress Scheme. It marked a historic move to secure contributions from the construction sector toward rectifying issues related to defective concrete products. The levy came into effect on September 1st, 2023, raising questions and concerns within the industry.

Initially, a range of precast concrete products were included in the levy’s scope. However, following careful consideration and consultations with industry experts, Minister McGrath has taken proactive steps to address these concerns and maintain a balanced approach.

Exclusion of Precast Concrete Pouring

In a welcome move for the precast concrete industry, Minister McGrath has confirmed that pouring concrete used for precast products will be excluded from the Defective Concrete Products Levy. This exclusion aligns with industry feedback and recognises the potential negative impact the levy could have had on the export of precast products and competition within the jurisdiction.

The amendment to the levy will officially take effect on January 1st, 2024. In the meantime, a refund scheme will be in place for the interim period until the end of 2023. This change means that concrete blocks and pouring concrete for uses other than in precast products will remain within the scope of the levy.

Minister McGrath expressed his belief that this amendment strikes a balance between funding the Mica Redress Scheme and minimizing the impact on inflation in the construction sector. The Department of Finance, in collaboration with Revenue, will closely monitor the introduction and operation of the levy and will continue to engage with industry stakeholders to address any issues that may arise.

Important Dates

The first filing date for returns related to the Defective Concrete Products Levy is January 23rd, 2024. This date should be noted by all relevant parties to ensure compliance with the new regulations.


O’Reilly Concrete welcomes the decision to exclude pouring concrete used for precast products from the Defective Concrete Products Levy. This amendment demonstrates the government’s willingness to listen to industry concerns and take necessary action to ensure the continued growth and success of the precast concrete sector.

We are committed to keeping our customers and partners informed about important developments in our industry. If you have any questions or require further information about how this amendment affects your business, please do not hesitate to contact us. Together, we can navigate these changes and build a stronger, more sustainable future for the construction sector in Ireland.
