Cor-Tuf UHPC was founded in 2016. We are the only licensed producer of Cor-Tuf Ultra-High Performance Concrete in the United States and the world. Cor-Tuf UHPC was developed by the U.S. Army Corps of Engineers (patent US 8016938 B2) in response to the need for a tougher, yet lighter material for protecting personnel and weapons facilities.
The company was founded by Douglas Darling, an entrepreneur with ventures that have spanned several industries, ranging from land development to insulation installation. Darling always had an interest in concrete as a construction material, with a desire to find a way to make it stronger and more durable. When Darling discovered the Cor-Tuf product developed by the U.S. Army Corps of Engineers, he immediately applied for a license to manufacture and sell the product.
At Cor-Tuf UHPC, we follow strict quality control measures to ensure our UHPC product meets standards of excellence. We are committed to helping contractors, engineers, architects, and other professionals understand the many benefits Cor-Tuf UHPC brings to projects, as well as the new and innovative uses Cor-Tuf makes possible for concrete.
