Etymology Composed of the words "hemp" and "concrete"
Definition Hempcrete is a material for construction and insulation (for wooden framed houses).
Hemp hurds are mixed with lime to create a substance which hardens like concrete. Proportions are different depending on the use: roof insulation, wall construction and insulation, floor screeding, renders and plasters.
As a breathable material, it regulates humidity levels well, avoiding dampness and condensation problems. Moreover, it is an ecologic alternative since hemp cultivation does not create any harmful effect on the environment because it does not need any fertilizer, or just a few, for its growth.
