The Conception of Geobind: A Journey from Idea to Innovation

The story of Geobind began during a time of uncertainty and reflection: the COVID-19 pandemic. Like many others, I found myself with unexpected time on my hands. As a builder, my projects slowed, and I began thinking about the future of the construction industry in New Zealand. It was clear that our sector would need to adapt to meet the demands of environmental legislation and the growing urgency to reduce carbon emissions. But how could we achieve this while still creating strong, durable, and cost-effective buildings?

This question became my driving force.

The Spark of an Idea

In my search for alternatives, I explored various sustainable materials, from strawbale to mudbrick. But it was hempcrete that truly stood out. Already being used successfully in Europe and Australia, hempcrete offered a carbon-negative, breathable, and mold-resistant solution. Its potential to regulate temperature and humidity was a game-changer for healthier homes. But there was one major barrier: New Zealand didn’t have a locally made binder suitable for hempcrete.

The cost of importing binders from Europe or Australia was prohibitive and defeated the purpose of creating a low-carbon solution. I realized that if I wanted to build with hempcrete, I’d need to develop a New Zealand-made binder. The idea for Geobind was born.

A Journey of Experimentation and Discovery

With a nudge from Northland Inc., I connected with Callaghan Innovation, whose support helped me take my initial idea from concept to research and development. The process was anything but straightforward. From literature reviews to initial testing with imported binders, I worked to understand what was already available and how we could improve it for New Zealand’s unique conditions.

We tested countless ingredient ratios, experimenting with locally sourced minerals and innovative additives. There were setbacks, breakthroughs, and a lot of perseverance. Along the way, I discovered that not only could we match international products, but we could also outperform them. The result was a binder tailored specifically to New Zealand’s environment—one that reduced carbon emissions and provided the strength and durability needed for construction.

The Role of Collaboration

This journey wasn’t mine alone. Geobind’s development relied on collaboration with scientists, industry experts, and organizations dedicated to innovation. Callaghan Innovation provided the resources to refine the binder’s formulation. NZTE, Creative HQ, and others helped me navigate the complexities of commercialization, from market strategy to product testing.

One of the most rewarding parts of this journey has been seeing the enthusiasm from builders, clients, and researchers alike. Geobind isn’t just a product; it’s a community effort to reshape how we think about construction and sustainability.

Building a Better Future

Today, Geobind stands as New Zealand’s first locally developed hempcrete binder. Its applications extend beyond traditional hempcrete walls to include bricks, acoustic panels, erosion control systems. Every product we create serves a larger purpose: to build homes and infrastructure that are healthier for people and the planet.

What started as an idea born of necessity has grown into a tangible solution with the power to transform the construction industry. Geobind is more than a binder—it’s a symbol of what’s possible when curiosity, determination, and innovation come together.

Looking ahead, I’m excited about where this journey will lead. With each project, we’re proving that sustainable building isn’t just a dream—it’s here, and it’s better than ever.
