\ik-ˈstrēm- känˈkrēt\

Noun. a modern eco-sensitive, high performance concrete material, engineered to utilize waste stream ingredients with the ability to be poured into an endless array of molds to create high impact LEED contributing architectural products.

It started with a simple purpose back in 1998: To exceed expectations and evolve eco-sensitive concrete materials into an accepted and modern aesthetic.

After years of intense R&D, that purpose was solidified in 2001 with the introduction of extremeconcrete®,  a modern-day, eco-friendly concrete material. Engineered to contain as much waste stream ingredients as possible, extremeconcrete® materials allow the creation of LEED contributing architectural products and surfaces while achieving the natural aesthetics and material properties of High Performance Concrete (HPC). The versatility of this ecologically sensitive material is one reason why extremeconcrete® is still used on notable projects across the globe to this day….Will your project be one of them?


above extremeconcrete® materials are shown in color #70-Natural.

Vibrant, fluid and textural, extremeconcrete® can be infused with a variety of pigments and recycled aggregates to provide unlimited color and material combinations to create unrivaled surfaces and distinctive products. Containing up to 85% recycled content (dry-weight ingredients), our proprietary extremeconcrete® mix designs can incorporate a variety of recycled/reclaimed elements diverted from the waste stream such as finely ground by-products from the production of silicon or coal-fired power plants, crushed pre/post -consumer glass, shredded circuit boards or plastics, stranded fabric or carpet fibers and even certain construction site and demolition waste diverted directly from your own LEED project. To help reduce the carbon footprint, all extremeconcrete® products use local sourcing seeking materials from a 500 mile radius wherever possible.
