GDI is a provider of 'better, faster, greener, and cheaper' clean-tech infrastructure solutions to fast growing markets. Our mission is to address the increasing demand for better infrastructure technology solutions in areas of the world that need them most, while at the same time emphasizing energy efficiency, environmental responsibility, cost effectiveness, local capacity building, job creation, and the use of rapid construction methodologies. GDI’s growing technology portfolio is divided into three areas: (i) vertical infrastructure (buildings, offices, houses); (ii) horizontal infrastructure (roads, railroad beds, foundations); and (iii) water & sanitation (water recycling, wastewater, desalination, and sewage treatment).
