Hempcrete blocks to be used to build annex in Littleover, Derby.
We have been selected to work on a project which specifies the use of hempcrete as as an alternative to traditional concrete blocks.
Hempcrete is a bio-composite that blends industrial hemp with a special lime-based binder which is then formed into building blocks. The building material is lighter, stronger and more elastic than concrete and is able to absorb and hold sunlight, making it highly sustainable. Other than offering high thermal insulation, hempcrete blocks will also pull carbon from the atmosphere and store it, offsetting the building’s construction.


Hi,
I did some work with hempcrete a few years ago, when there were only a couple of trial projects in the UK using this technology. How have things developed – was it fairly strightforward to spec. and build with?
