Sustainable Building System Featuring Carbon Capture

Product Specs

Just BioFiber Structural Solutions is committed to continuous improvement ( Kaizen) we have developed a series of building construction materials and systems. Our development values are; Safety, Sustainability, function, longevity, and healthy living.

The first product is the Just BioFiber modular block wall system which can be ordered in

11″ / 280mm width  8″ / 200mm Height, 21″/ 540mm Length

Unfinished blocks may be cut to size using standard power or hand saws. It is required that all fasteners be stainless steel or ceramic coated, to avoid corrosion.


The Super SSR Block building system is very cost effective and quick to construct, lowering labor costs and time to completion using Industry standard dimensions.

  • Strong vertical load bearing compression strength of over 40 MPa 36,000 lbs. per foot, 26-33 N/mm2
  • High Insulation R value R27 to R40 or λ=0.07W/m.K or RSI 0.176 or U.23
  • Very fire resistant > 1 hour rating
  • Easy handling with a solid feel, density of 11 kg (22 lbs) per block or 330 kg/m3
    • Standard SSR11 block size is 8″ 200mm height, 21″ 540mm width 11″ 280mm thick
  • Breathable Non Toxic walls that are moisture and air permeable
    • air permeability 0.7 gm/m2/mm hg
    • humidity permeability 23 gm/m2/mm hg
  • regulates temperature and humidity while retaining heat
    • heat capacity 1600 J/Kg
  • excellent acoustic properties Mean Acoustic Absorption Coefficient 0.7 NRC
  • You can help the planet; captures 130kg CO2/m3 with a Life Cycle Assessment of -108 kg CO2/m3
  • Life Cycle Assesment for Embodied Energy of 421 Mj/m2 and Embodied Carbon -17.6 Kg/m2
  • low labour costs and rapid construction; Labour is estimated at 32 sq. ft.or 1 M2 / man hour
  • interlocking design can be overlapped and turned 90 degrees for corners and intersecting walls
  • blocks can be cut in the field using hand or power tools; windows, jams and fixtures attach directly using ceramic coated screws
  • longevity, the building will last for over 100 years
  • Insect and mold resistant
  • Blocks are made using industrial hemp and lime without portland cement
  • Internal structural frames are made using advanced composites that are fire resistant without any (Red List) toxic ingredients

Specifications are subject to change as new and improved binders and processes are developed. Please contact us directly for military and severe environment product specifications.

We have developed a construction manual with detail drawings to answer your construction questions. please contact us by email.

A few questions;
– how is exterior and interior recommended to be finished?
– Is this rated for hurricane zones?
– What is used as headers above doors and windows?
-How is a roof typically tied to structure?

    Hi Jerry, as a follow up to our email reply we have added a construction manual link on this page.

Could you please point me to the construction manual.

Also I was wondering how the blocks are priced, can you give me a price per block or do you need to quote it based on a plan? I was also wondering what is the length of the blocks? Lastly do you have a distribution network or every order is shipped from your plant in Calgary (I’m in Halifax), I just trying to get and ideal on shipping cost?

Thank you

Hi Terry,

Since your system has 1 hour for fire rating at the present time, can we use 5/8 fireguard panels glued
to your block on both sides of the wall to have at least 2 hours rating. This is very important for
hi-rise structures for condo units, town houses, apartments. It can also a big help as for sound barriers.
Kindly respond to me or give me a call.

    Hi Angelito,
    Thank you for your your comment. Please wait until the 2 hour fire test is successfully completed using the new fire resistant composite internal frames. Our small scale tests have all passed so we expect the full size wall CAN?ULC S101 2 Hour will be certified in Q2 of 2017. we will post the results.

We are looking at the possibility of building a small guest cabin150 sqft? and would like to know more about the hempcrete blocks in terms of cost and transport costs (as opposed to building a full wall), as an option. We are on a small island off of Vancouver Island. Please email me.
