Formed in 1939, the O’Reilly Group is a recognised innovator in precast concrete, paving and environmental treatment systems.

The O’Reilly Group comprises four companies: O’Reilly Concrete; Barleystone Paving; O’Reilly Oakstown Environmental; and O’Reilly Precast UK, each setting high standards for innovation and reliability in the markets in which they operate.

These companies manufacture a wide range of innovative precast and pre-stressed concrete structural members, such as precast wall panels, pre-stressed floor slabs, pre-stressed and precast floor beams, portal frames, tanks and bridge beams.

O’Reilly Group’s head office is in Kingscourt, Co Cavan. Its concrete production facilities are dotted across several counties, in Bailieborough and Shercock, Co Cavan; Carrickmacross, Co Monaghan; and Clonmelon, Lobinstown and Oakstown, Co Meath.

Emmet Cosgrove, CEO, O’Reilly Group, says that the group is driven by a need to innovate and meet clients’ needs in a sustainable way.

“We have the most modern of production facilities, and we use the latest digital manufacturing and construction technology to ensure our products are fabricated to the most precise specification with the minimum of waste,” he explains. “We are also conscious of the fact that Irish-based developers and contractors need security, particularly at this time, about the cost and availability of product. The long-established relationships we enjoy and repeat business we continue to receive from our many customers is a testament to the service and product security that we provide for them.”

O’Reilly Concrete

O’Reilly Concrete Ltd is one of the largest precast frame manufacturers in Ireland and the UK, having designed, manufactured, installed and certified precast systems over the past 15 years. It has a library of prestigious projects for various clients. Indeed, in recent times, the company has expanded operations into central Europe, with ongoing projects in Germany.

The latest O’Reilly Group plant in Shercock, Co Cavan, is a state of the art facility where it manufactures architectural precast wall units. The facility is capable of manufacturing bespoke architectural walls panels designed by an in-house design team.

The range includes brick-faced precast panels, coloured rendered finished panels and other bespoke finishes. Using this system, the on-site construction phase of a project can be reduced by up to 50% with a very small crew compared to traditional build methods. The walls can be completed with windows and doors installed if requested, saving clients time and money.

This efficient modular building system has helped streamline the construction process. The rapid build system already has been utilised in a range of construction activities, from residential (houses and apartment developments) and office blocks to sports arenas and transport projects.
