Hempcrete also has the additionally useful properties of being breathable, fire-proof, pest resistant, and is a carbon negative material. It is carbon negative because of not only the carbon from the hemp plant itself, but with the lime it is mixed with, which wants to return to being a rock, pulls carbon from the air as the structure slowly petrifies. This means that the hempcrete will actually increase in strength and density as time passes. Coupled with the fact that it naturally breaths and regulates moister, there is no mold, dry rot, or other moisture related problems one typically finds in other construction. This would mean less energy going into a house built of hempcrete in the form of air conditioners or heaters, since the thermal resistance keeps a more consistent temperature inside the structure. Perhaps hempcrete will be America’s gateway product.
