Hempcrete Could Change The Way We Build Everything

Hempcrete is a building material that incorporates hemp and lime. It can be used for wall insulation, flooring, walls, and roofing, and fireproof, waterproof, and rot-proof. Insurance companies charge less to insure hempcrete homes. A Japanese home made of hemp is over 300 years old.

First off, what is Hempcrete? As the name suggests, hempcrete is a building material that incorporates hemp into its mixture. Versatile and hardy, it can be used for wall insulation, flooring, walls, roofing, and more, and is fireproof, waterproof, and rot-proof, provided it’s used aboveground.

Derived from the shiv or inside stem of the hemp plant, it’s then mixed with a lime base binder to create the final, negative carbon footprint product. Hempcrete is much more versatile and pliable than concrete, making it an easier material to work with. In fact, earthquakes cannot crack these structures, as they are three times more resistant to damage than regular concrete.

  2. “Are they exaggerating about climate change and how much OUR carbon is affecting it? Or are they so concerned with their system that they fear changing things? Either way, something is up here”.

    Great question…!


    • Good question, puppymonkey. In my view the greenhouse model of global warming is real and totally consistent with the Earth’s ancient history. I think where climate scientists have got into difficulty is trying to make mathematical predictions of how much warming to expect at what point in time. I have yet to see any modeling that takes into account our current Grand Solar Minimum, which clearly seems to have delayed the warming somewhat. I would be really interested if anyone has seen this type of modeling anywhere?

  4. I’ve done a self-install of hempcrete / bio-aggregate, as an internal wall insulation retrofit to my 130 year old victorian terraced house. It has massive potential not just for new-builds but for retrofitting older buildings whilst remaining sensitive to the needs & design of solid-walled (ie. no cavity) properties in terms of maintaining their vapour-permeability (aka. ‘breathability’) and managing moisture whilst retaining heat. It creates such a wonderful, warm cosy feel to rooms in a way I’ve not experienced with rooms that have synthetic insulation & plasterboard etc. There seem to be so many potential benefits. If you’d like to see what we’ve been up to, I’ve been doing my best to document this process along with the rest of the renovation here : https://bristolterracerestoration.wordpress.com/2016/12/07/hempcrete-downstairs-front-room-install-audit-nov-2016/
