Hemp hurds are mixed with a combination of lime products to produce a light weight, insulating, breathing material. The mixture of lime to hurds varies with the type of construction application and prevailing climatic conditions.

This hempcrete is cast around a timber framework. This is achieved by tamping down between shuttering, or it can be sprayed against a formwork (permanent or temporary). Internally a variety of finishes are possible. In this example the framework has been left exposed and the hempcrete finished with a natural paint.
