0808 Hemp-Based Bio Bricks:
The Future of Sustainable Construction
Introducing one of the first fast-curing, load-bearing, hemp-based building blocks globally. Made from 100% bio-based natural materials, our bricks are free from plastics, formaldehyde, and other toxic chemicals commonly found in traditional geopolymer materials.
Unlike conventional hempcrete blocks, which require wooden frames and mortar for installation, our Geohemp Bricks don’t require a support frame and can be interlocking, eliminating the need for additional materials, reducing labor time, and cutting costs.
At 0808, we are committed to revolutionizing the building industry by introducing environmentally friendly, high-performance alternatives to traditional materials. Our proprietary hemp-based Geopolymer blends are developed with sustainability, durability, and efficiency in mind, ensuring they meet the demands of modern construction while significantly reducing environmental impact.

Research-Backed Innovation
Studies have shown that incorporating hemp fibers into geo/hemp concrete enhances its mechanical properties while promoting sustainability. Research published in Minerals (2022) confirms that:
Sustainability & Carbon Sequestration
geo/hemp technology is a game-changer in sustainable construction, producing up to 80% fewer CO₂ emissions than raditional concrete. Unlike cement-based materials, geo/hemp does not require high-temperature kiln firing, making it an eco-friendly, low-carbon alternative. Additionally, its compatibility with natural aggregates like hemp hurd enhances arbon sequestration, further reducing environmental impact.
Enhanced Mechanical Performance
geo/hemp binders create a chemically stable, high-strength matrix that outperforms conventional concrete. When combined with select organic aggregates, the material achieves superior compressive strength, durability, and resistance to cracking, making it ideal for long lasting structures.
Superior Thermal & Acoustic Insulation
Due to its microporous structure and thermal mass, geo/hemp offers natural heat regulation and soundproofing, reducing energy demands for heating and cooling. Unlike standard concrete, it does not trap moisture, contributing to a healthier indoor environment.
Durability & Fire Resistance
geo/hemp is highly fire-resistant, capable of withstanding extreme temperatures without degrading—unlike traditional concrete, which weakens under high heat. Studies show that geo/hemp structures have the potential to last 100 to over 2,000 years, significantly outliving conventional cement-based buildings. It is also resistant to mold, fungi, and harsh weather conditions, ensuring long-term structural integrity.
Reduced Water Usage & Production Costs
Unlike traditional cement, geo/hemprequires little to no water during the curing process, drastically reducing resource consumption. Its rapid setting time and energy-efficient production lower manufacturing costs, making it an economically viable solution for sustainable construction
Prefabrication & On-Site Curing
Our bricks are designed to be prefabricated and delivered ready-to-use, curing in just 7 – 14 days compared to traditional hempcrete, which takes 4–6 weeks. Alternatively, they can be made directly on-site just one week before use, providing flexibility for builders and developers.
GEOhemp bricks
We offer two specialized types of Geohemp Bricks:
Structural Blocks
Designed for strength and load-bearing applications.
Insulation Blocks
Engineered for thermal and acoustic performance.
Why Choose Our Geohemp Bricks?
By replacing cement-based materials with geo/hemp and integrating industrial hemp fibers, we ensure a sustainable, cost-effective, and high-performance solution for residential and commercial construction.
With growing global interest in natural fiber-based building materials, 0808 is at the forefront of this innovation creating materials that are not only environmentally responsible but also built to last.
Join us in redefining the future of sustainable construction with hemp-based solutions.
