CRH

Crh Public Limited Company

A one of the world's largest makers of building materials, CRH supplies the cement, aggregates, and asphalt that go into roads, bridges, and homes across dozens of countries. It came to be in 1970, when Ireland's two biggest building firms—Cement and Roadstone—merged to form Cement Roadstone Holdings, whose initials it still carries. Its Roadstone half traces back to two brothers hauling sand and gravel around Dublin in a single truck.
