What is Hempcrete?
Hempcrete is a generic term for an old basic recipe of lime, hemp & water that has been used for decades in Europe for the restoration of old wattle & daub or cob construction.  A good reference source is "Tom Woolley - Hemp lime construction. A guide to building with hemp lime composites" or "Steve Allin (second edition) - Building with Hemp" for sale at our store for Au $ 40 + postage - please email us.

Hempcrete has been used by the Romans and in Japan centuries ago. These structures are still standing!

Unlike concrete or masonry, hempcrete does not crack severely under movement. Hence its suitability to be used in earthquake area's. It is also about the seventh of the weight of concrete. Lime is weak under tension and develops micro cracks under movement that seal when moisture comes into contact with free lime. Concrete or masonary will let go suddenly under movement which is why you get big noticeable cracks.


Hemp in Hempcrete
Hempcrete consists of hemp shiv, a short length hemp stalk by-product, and lime-based binder.  Industrial hemp with a THC content less than 1% is grown and used for fibre growth. Hemp is an excellent growth crop with many farming and environmental benefits:

Carbon Sequestration
Hempcrete is a carbon sink.  With 80-90% of its composition as hemp shiv, the majority of CO2 is sequestered by hempcrete is in the hemp growth with the remainder absorbed in the process of “carbotitation”.  This is the process where the lime-based binder absorbs carbon from the air continuously over time, petrifying the hemp shiv. Each tonne of lime-based hempcrete is estimated to absorb and sequester 249 kg of CO2 over a 100 year lifecycle.  Generally, hempcrete is estimated to sequester 110kg per cubic metre which will change depending transportation use.
