As the name suggests, hempcrete is a building material that incorporates hemp into its mixture. Versatile and hardy, it can be used for wall insulation, flooring, walls, roofing, and more, and is fireproof, waterproof, and rot-proof, provided it's used aboveground. Derived from the shiv or inside stem of the hemp plant, it's then mixed with a lime base binder to create the final, negative carbon footprint product. Hempcrete is much more versatile and pliable than concrete, making it an easier material to work with. In fact, earthquakes cannot crack these structures, as they are three times more resistant to damage than regular concrete.

Hempcrete also requires less energy to produce, since lime doesn't need to be heated to the same degree as industrial concrete. What's more, because it contains cellulose, Hempcrete also sequesters carbon.
