I’m from a farming/ranching background and now in the Construction Business.  I’ve been following how the hemp plant fibers can be utilized to build highly energy efficient homes when they are mixed a couple of natural products.

One of the products I’ve been following is called hempcrete.  It has the strength of concrete and is also energy efficient and removes and traps carbon from the air as it ages.  This to me is the ultimate in sustainability for future Missouri Homes and Buildings.  

I’ve also be researching how:

  1. hemp seeds can be turned into a form of oil and can be used as a bio diesel product for the transportation industry.  
  2. I’ve also seen a video by Henry Ford that showed he used the fibers from a plant to make early auto parts that were strong enough to take a blow from a hammer without damage.  

I’d like to see the State of Missouri Leading on the use of the industrial hemp plant-instead of falling behind other states and countries where it is working to create Sustainable Lifestyle.  Scotty

In my quest to promote affordable sustainable buildings for the St Louis region has lead me to discover a new building product that provides high Rvalue for energy efficiency and has the strength of concrete!

And when I learned that this revolutionary building product could be locally grown I believe I stumbled upon a viable solution that exceeds the needs of the growing Sustainable Driven Community.

Hempcrete Brick Wall Retrofit
Designed by Scotty- Stucco Like Finish Coat for Hempcrete Brick Wall Retrofit

One of the issues I’ve found while working on the brick buildings in the StLouis Region is the challenge of having adequate insulation on the exterior walls of the Masonry Structures.

These CAD designs by Scotty is one of the latest designs reflecting how this insulation could be installed over a Grid of #4 structural reinforcement.

      Hemp Plant Fibers are a natural product

                 that can be grown and sourced

                        from Missouri Farmers.

Hempcrete is as strong as Concrete with less damaging effects to our climate and provides a High RValue while adding Structural Reinforcement.

Stay Tuned for more information.  I will soon be posting information from a Sustainable Builder who has been involved in the Hemp Building Industry in Europe.

Mr Greg Flavall,  has given these suggestions:
    • Depending on age of buildings u can ascertain whether lime mortar was used or cement. Older buildings used lime in which case u could add hemp/lime “plaster ” to exterior or interior to increase efficiency as we have done many times in Europe. If cement forget it; you’re asking for problems.
    • In UK we have had problems in the early days adding hempcrete to cement mortared brick clad buildings bc they do not breathe and the hemp has deteriorated;…
    • Also u can use an alkali resistant mesh cloth embedded into the Hempcrete for added flexural strength and no need for steel reinforcing unless you are horizontally affixing steel plates to retain brick structure

Builders by trade we have built the first permitted hemp homes in USA.
Having evolved to encompass all aspects of Industrial Hemp from farm

to table we now teach others to grow, processing and use this miracle plant. Benefits of Hempcrete

Chances are increasing Missouri voters will weigh in; on marijuana legalization in the near future. Missouri Secretary of State Jason Kander announced Wednesday he has approved 13 different petitions to get an amendment on the ballot.

I just participated in Mayor Slays Mini Poll: In the Weeds and share my comment showing my support of growing and using hemp plant products.
