meet the team
Our team boasts over four decades of expertise in the construction sector, complemented by a globally acknowledged proficiency in geopolymer chemistry and its uses. We produce GeoCement among other geopolymer-based products, and work with our sister company, Sustainable Construction Solutions, and our partner, Constructions-3D, to develop and distribute 3D construction printers, mixers, and other equipment for the application of geopolymers.
Geopolymers and alkali-activated materials (AAMs) are often confused, but they differ in terms of chemistry and performance. At GPI, we produce aluminum silicate-based materials for a variety of applications. We are committed to advancing materials with enhanced functionality, resilience, and sustainability, while prioritizing safety and cost-effectiveness.
We are engaged in research, development, and production of geopolymer-based sustainable construction materials, alongside the equipment to mix and print them.
