We are North America’s largest manufacturer of building products and materials.
Imagine a company capable of providing the modern building materials needed to build our homes, schools, communities, even the bridges and highways to get you there. We are CRH, North America’s largest manufacturer of building products and the second largest globally.

In North America we adopted our parent company name to become CRH, but, the strength, quality and legacy of our Oldcastle brand remains in our product groups, Oldcastle Precast, Oldcastle Architectural and Oldcastle BuildingEnvelope®.

At CRH, we do more than manufacture products. We partner with our customers, design-build firms, construction professionals and owners to simplify the way we build and provide end to end solutions through our vertically integrated channels. We have the largest manufacturing footprint, the greatest product breadth, and lead many of the categories we work in. If you are looking to simplify the construction process, we can help you get there
