As reportedearlier, the CleanTech Open is a world wide competition and business accelerator for businesses in one of 8 categories of sustainable enterprises. The mission of the CleanTech Open is to find, fund, and foster entrepreneurs with big ideas that address today’s most urgent energy, environmental, and economic challenges. ArmaTerra Georeinforcing of Reno, NV became the Western Region Winner in the Green Building category in this 6 month program.
We are very happy and proud of this recognition. It is quite an achievement for us as we have been working on gaining more traction with the investor community,” said CEO, Sergio Nevel. “This award coupled with a recently issued patent will help to take us the rest of the way to commercialization.”
Michael Merrill, ArmaTerra’s Chief Technology Officer started working this idea several years ago. In 2009, he joined forces with Sergio Nevel to create a company to take his ideas to market. Since then, they formed ArmaTerra® Georeinforcing and began patenting Michael’s innovations. When retaining walls, slopes and levees are reinforced today, the state of the art is to use polymer or metal georeinforcing elements to strengthen the earth that is being retained and reinforced. ArmaTerra’s technology instead uses recycled tire treads that are uniquely configured and fastened using a proprietary non-corrosive fastening system.
Current products are less favorable than GeoTire® products because polymer based products are not as strong as metal and, therefore, less desirable for robust applications such as for use in highway construction. Metal is stronger and more widely used for such applications but presents other problems like corrosiveness which sometimes results in a reduced life and a high cost of trucking in special backfill when native soils amplify this problem.
GeoTire® provides the strength and non-corrosiveness because it is a product made with metal and coated with a synthetic cover. Tire treads are made with steel belting and are coated with a synthetic blend made of vulcanized rubber and latex. ArmaTerra’s process ensures that the metal is not exposed and the fastening system used to link as many treads as are needed for each job is made of a very strong non-corrosive nylon.
Of the 300 million waste tires generated in the U.S. each year, only 50% are beneficially repurposed. Approximately 40% are used as fuel and burned and 10% still end up in land fills. GeoTire® products put these tires to a higher and better use. They are also longer lasting, require no special backfill, are very strong and can save many private and public dollars when accepted and used in the construction of highways, rail systems, bridge abutments, marine applications, temporary and permanent retaining walls, mining and industrial roads/ramps, slope reinforcing, and in retrofitting existing earthen levees.
“We believe that our company and our products are perfectly poised to help America rebuild its infrastructure in a profitable, green, and sustainable way,” says Nevel. “This recognition goes a long way in acknowledging our vision and the clarity of our mission.”
ArmaTerra® Georeinforcing is an early stage start up Nevada Corporation that is currently seeking demonstration projects as well as investment from accredited investors in order to scale up operations.

That’s great news in the more Eco savvy states. I was stopped by the DEP of doing such a thing and could have been fined heavily if I didn’t take the tyre s off site and dispose of in a registered recycle plant.

Thanks for the insight and the advice. I would imagine new way of retaining walls would last longer with the proper drainage system behind them and if they were located in a shady area, regularly attacked by sprinklers or other forms of moisture.

Earthship Tire Retaining Walls

The same method for building structural walls in buildings can be applied when building retaining walls made with rammed earth encased in steel-belted rubber. Depending on the load the retaining wall is ‘retaining’, the batter and other adjustments should be considered.

Some tire retaining walls have been built up to 25 ft. high. Tires make an inexpensive solution that requires no concrete, wood or steel. The proper construction of a tire retaining wall involves filling the tires with dirt that’s compacted with a sledgehammer or a pneumatic tamper. We call this process “pounding the tires.” First, you place the tire on a level grade, then pound it, checking it for level. Always pound a tire in place. A 15-in. tire will take nearly 300 lb. of earth.
