Tools, equipment and method
Mixing hempcrete is not a pleasant job, but it needs to be done correctly.
The exact method for mixing hempcrete (including the specific amounts of water, hemp
and binder in mix) is dictated by the type of binder you are using. As has been said several
times already - it is an important point - you should always follow exactly the instructions
given by the manufacturer or supplier of the binder product you are using. Suppliers are
generally very helpful in passing on guidance issued by the manufacturer (and if yours is
not, find another supplier!). It is your responsibility as the builder to ensure that the fin-
ished building has full structural integrity. This is achieved by the correct use of materials,
which, as discussed, largely relates to the level of accuracy, and the method used, when
mixing the hempcrete.
On every build, someone needs to take overall responsibility for the training and super-
vision of everyone involved in this process, and monitor quality and consistency over the
whole build.
The exact proportions of hemp:binder:water vary slightly depending on the type of binder
used and the application (floors, walls, roof, etc.) in which you are using it. For this reason,
