Hempcrete is made of the inner woody core of the hemp plant (hemp shives), a lime-based binder, and water.
Hempcrete is easier to work with than traditional lime mixes and acts as an insulator and moisture regulator. It lacks the brittleness of concrete and consequently does not need expansion joints.
Typically, hempcrete has good thermal and acoustic insulation capabilities, but low mechanical performance, specifically compressive strength. When used in prefabricated blocks, hempcrete acts as a carbon sink throughout its lifetime. The result is a lightweight, fireproof, insulating material, finishing plaster, or a non-load bearing wall, ideal for most climates, since it combines insulation and thermal mass while providing a positive impact on the environment.
