North America’s leading manufacturer of concrete building and hardscape products. 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.
