Geofortis -

Solving a Concrete Industry Crisis


Geofortis is developing innovative technologies and products to solve an increasingly severe challenge to the concrete industry.  At the core of Geofortis is an age-old pozzolan mineral.  Ancient Roman structures built with similar materials still stand today.

The primary pozzolan in recent years has been fly ash, a residual from coal burning power plants.  Production has diminished as coal plants close or convert to natural gas.  The Western U.S. is facing supply shortages of fly ash, creating big problems for concrete suppliers, including contract delivery issues, cost, capacity limits, quality, and performance.  Significant additional closures and conversions are scheduled, creating a bigger deficit in an already constrained market.


Before the widespread use of fly ash as concrete additives, natural pozzolans were successfully used as a raw ingredient in concrete to improve performance and durability.  Now that the availability of fly ash is limited and costs increase, a replacement is needed.  Geofortis is bringing natural pozzolans that have a proven track record of meeting these needs back to the market.

Innovative Engineering Creates Best Products

Our dedicated Research and Development team has conducted thousands of tests over 3 years to identify and prove the efficacy of our natural pozzolans for concrete additives.  We have worked with  large concrete producers to establish market presence and acceptance. We have demonstrated the benefits of our products both in the lab and in full scale concrete pours.

Our products improve concrete strength and durability, reduce permeability and provide cost savings for producers.  Many areas face severe problems due to poor quality aggregates that are solved by the addition of Geofortis' natural pozzolan products.


New Production Facility to Serve Western US

First Plant in Reno, NV to Serve Northern CA, NV, UT, ID & WA Markets

Geofortis has  designed a processing plant to mill and blend  natural pozzolans and other ingredients at our 18 acre plant site in Reno, NV. The plant is just 20 minutes from our mine site with rail and freeway access.

Our processing facility is designed to produce 600,000 tons of product per year.  Construction is to begin in 2019.  The plant will be a state of the art design to achieve efficiency and harmony with the industrial zoned location.
