BIOTEKT USA, LLC is an American limited liability company constituted in the State of Florida. We fabricate and sell components and kits for the patented BIOTEKT systems of earth-sheltered construction, ECOSPHERE™ and OASIS™.



Manuel Lago Granger, architect and ecologist, (and Biotekt's CEO and co- founder), formulated the concept and designed the first prototypes for a "prefabricated, modular system of earth-sheltered building in composite materials". 


A local group in Colombia formed a company called COLFIBREX S.A.S. to market Manuel's design, which was initially called the "Green-House System". Although the Colfibrex website is no longer online, you can check out its history at www.archive.org or go here for photos and videos of generation one...


Despite world-wide interest in the system, and the many homes and buildings that were successfully built in different countries, COLFIBREX shut it's doors in 2013. As a first generation product, the system had many issues that needed some thought; production was cumbersome and slow, designs lacked flexibility, and the panels themselves needed to have a larger strength margin... Convinced that the lessons learned were greater than the time lost, Manuel started to look for investors and opportunities to continue with his ideas. He also took the opportunity to completely redesign the system, creating a true second generation product that would become a new standard in efficient earth-sheltered construction.


Manuel travelled to the UAE and Oman, where he developed prototypes for a variant of the system that had become an obvious necessity during previous travels to the Middle East, using composites in combination with one of the most abundant (and previously considered useless) materials in the world, desert sand. These prototypes formed the basis for the new system of sand-sheltered building, OASIS™.


BIOTEKT USA, LLC. was founded by Manuel and Ecosphere Llc, an American company. 

2018 -

At this time, BIOTEKT has two production facilities in South America, one in the Middle East, and is getting ready to start production in Canada.. we are getting closer and closer to being able to make a real difference in the housing and sustainable construction industry worldwide.
