Dazed and … Constructed? How Hemp Could Alter Material Selections in Architecture


For architects and clients seeking a structural material, Calgary, Canada–based JustBioFiber offers a hemp-based modular block for load-bearing wall construction. The Super SSR Block exhibits a compressive strength of more than 5,800 psi, which compares favorably to the range of 1740 psi to 3045 psi typical for CMUs. Additionally, the product is an excellent insulator and is highly fire-resistant with over a one-hour rating. Super SSR Block also has high thermal mass, can regulate temperature and humidity, is breathable, and resists mold and pests.

Jack Anderson Greenplan Interview

Jack Anderson Greenplan interview with Canada Citizens Forum

For as long as the human race has existed, people have continuously worked towards improving the quality of life, both for themselves and for future generations. From life in the wilderness, to life in villages and cities—people have advanced. We help each other to live better. In the desire to help more people, the industrial revolution brought a whole new approach to the production of goods. More people than ever were empowered to improve their quality of life. Now, as time goes by, technology continues to assist humankind in reaching ever new heights.

Although our rapid advancements in technology were nothing short of amazing, they came with a cost. Intensified human activity has placed nature, and the environment at risk. For hundreds of years we have used the resources that surround us, while not fully understanding the extent of the damage we have been causing to the planet. Now, to ensure that future generations can enjoy the wealth and beauty of our planet without compromising quality of life, we need to find a far better way to support the environment and sustain human existence! But where… and what is it?

Just BioFiber has the answer for the built environment—by rethinking how we build and allowing natural biological functions to convert and store greenhouse gases in natural plant materials and then using those plant materials in our permanent building structures. This application of natural biological fiber has the potential to remove and sequester vast amounts of carbon dioxide from the atmosphere. Also, the increased insulation and thermal capacity qualities of our sustainable building materials further reduce the energy required to heat and cool these buildings.

Just BioFiber Structural Solutions Corporation is a Canadian company, registered in Alberta, which has developed a unique, renewable, and sustainable building construction system that not only offers cost savings from energy efficiency for building owners and operators, but also addresses climate change by absorbing the greenhouse gas—carbon dioxide. The Super SSR (Structural, Sustainable, R-Value) building system consists of natural fiber construction blocks that are designed to be strong and safe, with excellent thermal qualities that also offer ease of construction and finishing.

The system utilizes the industrial hemp plant as the base material for its building blocks. Hemp is a sustainable, renewable, carbon dioxide absorbing, temperature and drought resistant crop that provides a new opportunity for farm income diversification. Did you know that before the blocks are even produced, the reduction of carbon dioxide in the environment already begins? A one hectare of hemp crop will consume over 10 tonnes of carbon dioxide annually while the plants grow, 4 times more than a hectare of mature trees in a forest.

The preferred hemp and lime formulation make the Super SSR building material organic and bio-recyclable. The structural, modular blocks are designed to be simple and very builder friendly—as easy as building with Lego. In addition, the production process of the blocks allows us to capture and reuse heat and water that otherwise would be wasted. How? The carbon dioxide and water from the combustion waste of natural gas is integrated into the fabrication process. Beyond “carbon neutral” the resultant “carbon less-than-zero” building construction materials will significantly reduce energy requirements in buildings for heating and cooling, and lower operating costs. The result is a very affordable building construction system that sequesters more greenhouse gas than is emitted in its production, all with very low embodied energy.

The SSR block system has a strong vertical load bearing compression strength. Testing has also shown that the blocks are very fire resistant and able to withstand a 940°C fire for over 1 hour and maintain its structural integrity. The system also has exceptional thermal resistance, with a value up to R40, allowing it to regulate temperature and humidity while retaining heat. It has excellent acoustic properties, and is capable of capturing 130 Kg of carbon dioxide per cubic meter. The system also provides healthier indoor air quality due to its breathable, non-toxic, vapor permeable, insect and mold resistant walls. The buildings built with the Super SSR building system will continue to sequester carbon, increasing in strength as it does this for up to 100 years and lasting well beyond.

Because of the patented design and material qualities, the Super SSR blocks produce safe, strong buildings that will protect you from wind, rain, snow, heat, cold, earthquakes, hurricanes, tornadoes, insects, mold and even fire. Super SSR blocks are not just exceptional building materials, they also promote “green building”, “green living”, and environmental justice.

The market for new construction of wall systems for both residential and commercial buildings is estimated at 4.2 billion dollars in Canada, 49.5 billion dollars in the United States and 1.237 trillion dollars in China. A potential U.S. and Canadian market opportunity of only 1% would require the production of 2.3 million blocks per month with a sales value of over 500 million dollars per year. Transparency Market Research studies projected the Green Building Materials Market is to reach 243.77 billion American dollars by 2019.

Our market differentiation pertaining to carbon sequestration, energy efficiency, fire resistance and acoustical properties places Just BioFiber in a unique position to capture market share quickly.

As an initial market focus, Just BioFiber is looking to target segments of the market in Western Canada that have shown interest in:

1. Commercial demising walls where building code requires a 1 hour fire rating

2. Commercial exterior wall systems for buildings where operating costs of heating and cooling are directly related to property valuation

3. Residential exterior wall systems where cost and ease of construction are paramount in bottom-line profitability. We can meet these specific demands and improve upon energy efficiency, indoor air quality and sound attenuation, adding substantial value.

Just BioFiber’s Super SSR building system is ultimately the most sustainable building system on the market; it absorbs carbon dioxide, provides healthier and more economical living and working environments and yields excellent opportunities for investment.

The Super SSR building system is the first viable sustainable building product and a worthy investment in environmental justice.

Please explain exactly how the SSR blocks capture CO2 in a finished building. Can you point me to a peer-reviewed journal paper that reports on measurements of this capture and how they vary over time.

    Thanks Great question. We use Lime as our hemp binder, without portland cement.
    When limestone/chalk (calcium carbonate) is burnt in the kiln it turns into quicklime (calcium oxide) and releases carbon dioxide.
    Water can be added to quicklime/burnt lime to produce hydrated lime (calcium hydroxide).
    Over the lifetime of lime products, carbon dioxide is gradually re-absorbed by lime from the air, which is known as recarbonation. Chemically, this begins to turn the lime back into calcium carbonate.
    Here is a link to the British lime association with a detailed chemical explanation.

Well done, look like a great product with great potentials. I have a long history with hemp fiber i did build with hemp crete in Vancouver BC, and i used the Italian version of Hemp Brick to build a cottage in Italy. I’m a contractor here in Calgary, I know quite well this product as an installer, also i do my own lime mix for Stucco and hemp Plaster, I also did experiment finishing like American Clay, Lime Wash, and Venetian Plaster over Hempcrete. I also did direct the workshop at 2010 Hemp Convention in 100 mile house BC. If you need a contractor for any project I would love to partecipate.

Thanks, this an exciting construction material and it suggests that it offers a range of finishing options beyond American Clay/plaster. I would love to hear more about “ease of construction and finishing”, but mostly finishing. Can you use conventional adhesives that are non toxic and traditional fasteners by drilling into the hempcrete? Can you run plumbing and or electrical through the blocks or must they be run inside the finished walls? Would altering the blocks like this reduce the R value dramatically? Would love to know more.

    Thank you for your posting.
    The most common interior finishing is directly applied lime and clay plaster and the exterior finishing is standard lime stucco. Because the walls “breathe” there needs to be either an air space or a semipermeable finish material. Any finish may be used as long as an air space is maintained between the finish and the wall using furring. Traditional non corroding screw fasteners may be used to attach directly to the wooden structural supports embedded every 12cm. Vertical electrical conduits are also built into the design at the same intervals. These are designed as exterior walls so it is not recommended to install plumbing in any exterior wall due to freeze risk and reduced thermal insulation. Interior walls would be standard wood frame cavities for placing plumbing and they would be attached directly to the BioFiber wall imbedded wood supports using longer ceramic coated screws. There is a construction guide and video in progress.
