Cor-Tuf UHPC: Simple, Strong and Cost-Effective

Other UHPCs can be costly and complicated — requiring special mixers, tricky batching, foreign sourcing, and hidden costs.

Cor-Tuf UHPC puts you in control. We’ve taken Army Corps technology and engineered it into commercially viable products – CT25 and CT420 – that use your sand, your cement, and your existing equipment. The result: simplified installations, unmatched strength, and American-made reliability.

Faster, Cheaper Installs

Faster, Cheaper Installs

  • Mixes in standard ready-mix trucks. See our Ready Mix Partners
  • No on-site staging, mixing or icing required
  • Quickest Mix of Any UHPC (Ready in 8–12 minutes)
  • Longest batch life (5+ hours in spec)
  • Longest workability (100+minutes)

Engineered to Endure

Engineered to Endure

  • Up to 10X stronger than regular concrete
  • Best-in-class chloride resistance
  • Performs in extreme climates without degradation
  • 100+ year lifespan reduces maintenance and rework

Lowest Long-Term Costs

Lowest Long-Term Costs

  • Lowest cost fully installed UHPC on market
  • All-inclusive pricing = better bid accuracy
  • No hidden labor or site prep costs
  • Reduced shipping costs by using local sand and cement
  • Less product waste

Reliable, Domestic Supply

Reliable, Domestic Supply

  • Buy-American compliant for federal and state projects.
  • Built from local materials using existing sand and cement supplies
  • Based on the US Army Corps formula, perfected for commercialization by Cor-Tuf LLC
  • Dependable sourcing that reduces delays with shorter lead times

The Concrete of the Future, Born from Military Innovation

Founded in 2016, Cor-Tuf UHPC LLC brings to market an advanced Ultra-High Performance Concrete (UHPC) invented by the U.S. Army Corps of Engineers (Patent No. 8016938 B2). Originally designed to protect critical facilities and personnel, Cor-Tuf has improved and perfected this technology — making it practical for large-scale infrastructure, precast, and utility projects while solving the challenges that limit other UHPCs.

With our proprietary formulations, CT25 and CT420, we continue to push UHPC forward — delivering battlefield-grade strength with real-world usability, cost efficiency, and sustainability.

Proven Performance: Tested at 1,250+ psi tensile strength, nearly 3,000 psi flexural strength, and 25,000+ psi compressive strength, our UHPC products are also resistant to water, freeze-thaw cycles, corrosion, and abrasion. This unmatched performance sets a new benchmark for structural, precast, and civil engineering applications.

Backed by more than 150 years of combined experience in infrastructure rehabilitation, our team understands what contractors face on the job site — and how to make UHPC work in the real world. We stand behind every pour.

The future of concrete is here—and it’s ready for your next project.

Cor-Tuf Selected for Major Infrastructure Project in NYC (Sept 2025)

“Working with Cor-Tuf UHPC on the Park Avenue Viaduct project has allowed Halmar to meet complex design requirements with proven solutions,” Halmar Project Engineer Peter Alonge said. “The material’s strength and ease of placement support the MTA’s long-term goals for safety and reliability."

What Makes UHPC Ultra-High Performance

UHPC achieves its superior performance through a dense nano-scale matrix that is far less permeable than conventional concrete. This matrix is combined with steel fiber reinforcement, which provides exceptional ductility and crack resistance.

Though exact formulations and results vary by producer, UHPC generally incorporates a blend of Portland cement, sand, supplementary cementitious materials, chemical admixtures, and fibers – resulting in a material dramatically stronger, tougher, and longer lasting than traditional concrete.
