Hempcrete is a non–load-bearing enclosure material made from hemp shiv (the woody core of the hemp plant) mixed with a lime-based binder and water. Thanks to its highly porous structure, hempcrete has a low thermal conductivity, keeping walls cooler while allowing vapor permeability and natural moisture buffering—reducing condensation and mold growth.
This material is used for infill or enclosure walls, panels, and plaster layers over load-bearing frames (reinforced concrete, steel, or timber). It is suitable for low-rise housing and renovation projects, particularly in hot and humid climates.
From an environmental standpoint, hempcrete utilizes renewable biomass and has the potential to store biogenic CO₂ and absorb additional CO₂ through carbonation over its lifetime. However, being “carbon negative” is not automatic—it depends on the mix composition and the overall supply chain. In some countries, hemp-lime construction already has established frameworks for low-rise buildings.
