Changing the world one pour at a time.

The first and only licensed producer of Cor-Tuf® UHPC.

Cor-Tuf is the exclusive licensed producer of Cor-Tuf Ultra High Performance Concrete (UHPC) in the United States and the world. Cor-Tuf UHPC is the premier material for Low Impact Design (LID). It is a class of concrete that is exceptionally strong, durable, and cost effective.

Originally developed by the U.S. Army Corps of Engineers, Cor-Tuf UHPC is unique in its ability to deliver the strength of steel at a lower life cycle cost. The benefits of Cor-Tuf UHPC demonstrate its superiority to steel:
Cor-Tuf UHPC is the ideal replacement for steel and traditional concrete on your next construction project. When directly compared to equal steel components, Cor-Tuf UHPC delivers the same strength and durability. Reduced material requirements lower the overall cost of materials and reduce the carbon footprint associated with construction and maintenance.

The exceptional durability of Cor-Tuf UHPC delivers a lower total life cycle cost while delivering the additional benefits of safety, resiliency, and energy efficiency.

Your Sand, Your Cement, Our UHPC

Finally. A UHPC that makes sense financially and can be mixed in a ready-mix truck.

Cor-Tuf UHPC is the most contractor-friendly and cost-effective UHPC available, a perfect addition to any cement or concrete company’s offerings. 

Developed by the Army Corps of Engineers, and licensed exclusively to Cor-Tuf, our CT-25 can be delivered and used in all the ways that traditional concrete is mixed, including ready mix trucks. Our CT-25 formula can be mixed while in transport, or on the job site. 

We demonstrated this capability recently, mixing on site at Rockingham Precast in Rockingham, Virginia. We created three decorative, blast-resistant panels. It only took 8.5 minutes to mix the materials in the truck, and samples sent to Durastress had a compressive strength of 17,470 PSI after curing for only 13 days. It takes traditional concrete 28 days to reach a top compressive strength of 5,000 psi; the Cor-Tuf UHPC can attain a compressive strength as high as 50,000 psi. 

Best of all, all you have to buy from us is our UHPC; you or your customers can use their own sand and cement. Other UHPC manufacturers insist that you buy and use their sand and cement, which drives up the cost; our solution is about half the cost of the nearest competitor. 

CT-25 has been thoroughly tested by many state and federal DOT entities as well as the Army Corps of Engineers, and meets or exceeds all material testing protocols for UHPC to date. In one test conducted by the Army Corps, blocks of UHPC concrete  have been sitting for 25 years in the crashing waves of the North Atlantic. So far, chloride ion salt has not penetrated more than 5 millimeters into the surface of the material. Cor-Tuf UHPC has also been thoroughly tested by Cor-Tuf and used in a variety of projects. 

Our CT-25 has a useful life of hundreds of years and is 10x stronger than traditional concrete. It is non-porous and can be used for a wide range of projects, including repairing failing traditional concrete; joining precast panels; building bridges, buildings, seawalls, and dams; H beams and box beams; and creating intricate but blast-proof architectural facades.

The ingredients used to manufacture Cor-Tuf UHPC are approximately 80% the same as traditional concrete. It is what goes into the remaining 20% that makes Cor-Tuf unique and innovative.

We are absolutely driven to put Cor-Tuf into the hands of as many contractors as possible, because it solves all of the problems inherent in traditional concrete, while at the same time fitting right into the normal contractor methods used to mix, transport, and pour.

Cor-Tuf UHPC Mobile Batch Plant
Our new fully-automated mobile concrete batching plant for Cor-Tuf UHPC has been tested at Dura-Stress, Inc., in Leesburg, FL and is ready for operation. See for yourself how this well-engineered portable batch plant solves the problem of onsite mass production. This results in a consistent process that can be certified by a printed batch ticket for every load produced.

Cor-Tuf UHPC has a 100-year product lifespan.

Cor-Tuf In Action: H-Piling Test
In this Cor-Tuf UHPC three-day testing event, we poured two 30' beams, one 63' beam, and two 30' H pilings. We also demonstrated the user-friendliness of the product by producing all of the components with industry standard ready-mix trucks.
