Hempcrete cast on stone wall

An example of a cast hempcrete wall inside of an old stone building using it as insulation and modulation of humidity. This also shows a spray technique using the 3CM hemp spraying system. It's important to remember that this was done on tested matched pairs of binder and hemp hurd. This is done to insure that performance characteristics are consistent in labs and on build site. This usage of hemp lime and some builds are done in hemp clay, may seem controversial to some due to the walls build and it's reduced ability to perform as a "vapor permeable" system. This goes hand in hand with my video showing hempcrete cast directly on a concrete tip up wall. It's important to note that every build using this technique must be carefully assessed.
