The Story of CRH

Our roots are ingrained in the rich history of two entrepreneurial brothers who went into business in 1930s Ireland with nothing more than a sand and gravel pit and a single truck. Our growth has been fueled by the pioneering spirit of our first employees, who forty years later crossed the Atlantic Ocean full of optimism and a commitment to building relationships. They sealed the first deal, acquiring Amcor in 1978, and planted CRH’s first footprint in North America under the name Oldcastle. Today, operating under our parent company name CRH, we are the largest building materials company in North America and we embody the values of the hundreds of entrepreneurs who make up our family of businesses.

Oldcastle is now CRH Americas, the North American arm of CRH, a global leader in the building materials industry. Our success has been founded on delivering high performance and growth through our people - our most important asset.  

We provide a decentralized, entrepreneurial environment, where decisions at all levels drive performance.  Take charge of your career and leverage the network of global resources and growth opportunities!

CRH employs 85,000 people at 3,600 locations in 32 countries worldwide, providing more opportunities to advance your career.   Our range of businesses and worldwide locations, along with our growth aspirations, enables us to provide great career opportunities for our people to develop and succeed.
