Roadstone

What Roadstone does

Roadstone Ltd is Ireland's leading domestic manufacturer and supplier of construction and building materials, operating as a wholly-owned subsidiary of CRH plc since the 1970 merger between Roadstone and Irish Cement that formed Cement-Roadstone Holdings (now CRH). Founded in 1949 by Tom and Donal Roche in Dublin and tracing its origins to an early-1930s haulage business in Inchicore, Roadstone today operates a nationwide network of 56 depot, quarry, and concrete plant locations across the Republic of Ireland, employing 10,000+ people. The company manufactures and distributes ready-mix concrete, aggregates, asphalt and macadam, concrete blocks, paving, roof tiles, mortar and renders, floor screeds, stormwater management products, decorative stone, and agricultural lime (Grolime).

The company's product and technology portfolio is anchored in regulatory compliance and decarbonisation. Flagship innovations include the Thermal Liteblock System (thermal conductivity as low as 0.33 W/mK for TGD Part L compliance), next-generation asphalt using 70% reclaimed asphalt pavement and a lignin bio-binder achieving a 94% CO2 reduction versus conventional asphalt, and Ireland's first cement-free geopolymer (3D-printed) developed with Trinity College Dublin from industrial-waste red mud carrying around 70% less embodied carbon. Roadstone holds first-in-Ireland CO2 Performance Ladder Level 5 certification, CE marking under I.S. EN 771-3 System 2+ on key blocks, and ISO 9001 / 14001 / 50001 / INAB 17025 accreditations across operations. Distribution is served by an owned fleet that has begun transitioning to battery-electric concrete mixers powered by a 4MW solar array at its Belgard quarry.

Revenue is generated through a B2B/B2C quote-based sales model: customers request pricing via roadstone.ie, depot walk-ins, or account customer portals, with pricing varying by product, volume, and location. Roadstone sells across four primary segments — residential construction, commercial and high-rise construction, civil engineering and infrastructure, and agriculture — and supports its market position through CPD-accredited technical seminars, partnership with TII on recycled-aggregate specifications, RTE's DIY SOS charity builds, and a stream of Irish Concrete Society award wins for flagship projects including Páirc Uí Chaoimh stadium, the Rose Fitzgerald Kennedy Bridge, and the 25-storey Railyard Apartments in Cork.
