Lego-Style Hempcrete Blocks: A Sustainable Building Solution

Terry Radford

In the thought-provoking video titled “Amazing Lego-Style HEMP BLOCKS Make Building a House Quick, Easy & Sustainable” Terry Radford, CEO and Co-Founder of ‘Just BioFiber‘ takes us on a journey into the world of hemp construction. With their innovative hempcrete blocks, Radford and his team are revolutionizing the building industry by providing an environmentally friendly and practical solution. This article explores the key highlights from the video, showcasing the immense potential of hemp as a sustainable building material.

Lego-Style Hemp Blocks

Terry Radford introduces us to the concept of hempcrete blocks, referring to them as “Lego for adults.” These unique building blocks, made entirely from hemp, offer a range of advantages over traditional construction materials. Hempcrete, a mixture of hemp hurd and lime, proves to be an exceptional insulator, fire-resistant, and environmentally friendly.

The Power of Hempcrete

Hempcrete’s composition, derived from the inner core of the hemp plant, known as hemp hurd, combined with lime, brings forth remarkable properties. Radford highlights that hempcrete offers all the benefits of concrete walls but with half the weight and ten times the insulation. Its lightweight nature and superior insulating capacity make it an attractive option for builders and homeowners.

Lego-Style Design for Ease and Efficiency

The hempcrete blocks developed by ‘Just Biofiber’ are designed with practicality in mind. Weighing in at 25 pounds, they are easy to handle and stack, thanks to their interlocking design. The company offers two types of blocks: heavy-duty frames capable of supporting walls up to 30 feet high, and light-duty frames designed for residential buildings up to 20 feet. With built-in holes for electrical lines and easy on-site customization, the blocks demonstrate forward-thinking design and functionality.

Environmental Advantages of Hempcrete

Hempcrete boasts a range of environmental benefits. As a rapidly renewable resource, hemp requires minimal water and grows quickly, making it an ideal choice for sustainable construction. Moreover, hemp absorbs and sequesters carbon dioxide during its growth, making hempcrete a carbon-negative material. The combination of hemp hurd and lime creates a material that is not only durable and insulating but also environmentally friendly.

Overcoming Challenges for Structural Integrity

Radford shares the journey of developing the inner frame material for the hempcrete blocks. Initially considering wood, they faced inconsistency in the strength of the material. To address this, they created a bio composite using vegetable oil-based polyesters. This innovative material provides the necessary strength, durability, and resistance to deformation, even in extreme temperatures.

Embracing the Benefits of Hempcrete

One of the common questions ‘Just Biofiber’ encounters is, “Why Hemp?” The answer lies in the multitude of benefits that hempcrete offers. Its insulation properties provide energy efficiency, reducing heating and cooling costs. The material’s thermal capacity helps regulate temperature, creating comfortable indoor environments. Hempcrete’s fire resistance, humidity regulation, and noise reduction qualities make it an attractive choice for builders and homeowners seeking sustainable and high-performing construction materials.

From Misconception to Recognition

Initially, ‘Just Biofiber’ faced misconceptions and jokes due to the association of hemp with marijuana. To overcome these hurdles, they temporarily branded their product as “bio fiber.” However, as public understanding of hemp and its benefits has increased, they proudly embrace the term “hempcrete.” This shift reflects the growing acceptance and recognition of hemp as a valuable and sustainable resource in the construction industry.


The video, “Amazing Lego-Style HEMP BLOCKS Make Building a House Quick, Easy & Sustainable,” sheds light on the remarkable potential of hempcrete as a sustainable building material. Terry Radford and his team at ‘Just Biofiber’ have revolutionized the construction industry by offering lightweight, insulating, and environmentally friendly hempcrete blocks. With their innovative design, focus on regenerative agriculture, and commitment to sustainability, they are paving the way for a greener and more sustainable future in the realm of construction.
