Practice Hemp Building Construction
MATERIAL COMPOSITION HempiCAST is a bio-composite premix material, ideal as an insulated wall solution for low-rise external walls in extreme climatic conditions. It can also be applied as acoustic internal walls. Mixing our specially selected hemp hurd and formulated lime based binder, the designer has the flexibility to vary finishing texture (based on formwork used), colour hue of wall (by adding inorganic pigments), or lime plaster and paint (with breathable paint eg. mineral silicate) to their desired wall design effect.
Illustration images of cast in-situ with HempiCAST (mixing packs of HempiHURD and HempiBIND)
CAST IN-SITU CONSTRUCTION METHOD
Formwork shuttering boards can be in whatever available resource in the region. Ideal for hard to reach site with
available workers. Skills, tools and equipment required for cast in-situ method is quite similar with concrete material.
Except that instead of using concrete mixer, Pan Mixer with rotary blades is more ideal. Also, additional tamping
process to compact the poured HempiCAST mix into formwork is required. Formwork can be removed after 24hours
where casted hemp wall shall be left curing under shelter protection from rain.
We can provide training workshops of building demonstration to the project builders or contractor teams upon
request.
