What is Hempcrete? Hempcrete is a building material that incorporates hemp into its mixture. Hempcrete is very versatile as it can be used for wall insulation, flooring, walls, roofing and more. It’s fire-proof, water-proof, and rot-proof as long as it’s above ground. Hempcrete is made from the shiv or inside stem of the hemp plant and is then mixed with a lime base binder to create the building material. This mixture creates a negative carbon footprint for those who are concerned with the carbon side of things. Hempcrete is much more versatile, easy to work with and pliable than concrete. In fact, earthquakes cannot crack these structures as they are 3 times more resistant than regular concrete.
Hempcrete is a much more superior building material due to the fact that it is a very strong, lightweight and breathable material. When used as exterior walls, it lets water in without rotting or damaging the material. In a practical sense, instead of needing to build homes with space between exterior walls, which are then filled with insulation, you can simply use a Hempcrete wall. As humidity is taken in from the external environment, the Hempcrete holds that humidity until it is ready to be released again when the climate is less humid. Since the lime is wrapped in cellulose, the lime takes a bit longer for it to fully petrify but is still incredibly strong.
Over time, the lime looks to turn back to a rock, so the material becomes harder and harder until it petrifies completely. This means the wall will last thousands of years vs. 40 – 100 like normal building materials today. Another great aspect to Hempcrete is that if too much is mixed during building, you can return it to the soil as a great fertilizer. Since hemp grows to maturity in just 14 weeks, it is a very powerful, versatile, cheap and sustainable solution.
