Hempcrete Could Change The Way We Build Everything

By Joe Martino

url-1When it comes to new and sustainable housing ideas, it seems to always be about creating a more efficient home in terms of insulation, lighting, electricity etc. Mainstream belief  on the subject would have you believe that top corporations and government projects are working with the best possible technology to bring forth solutions that work and are going to be great for the environment. If that was truly the case, I can guarantee you that the whole world would be using Hempcrete right now. Haven’t heard of it? Not too surprised.

First off, 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. It is the worlds strongest building material and 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.

Since lime is the binding material, builders do not have to heat up the lime as much as they would if they were creating concrete. This results in a lot of energyurl-4 conservation when producing Hempcrete vs. concrete. Jumping back to the carbon aspect, Hempcrete sequesters (hides or puts away) carbon as it is very high in cellulose. Through it’s growing life cycle, it takes in large amounts of carbon which is then built into the home or building it is being used to construct. This dos not allow the carbon to be released into the atmosphere. A home can save about 20,000lbs of carbon when being built out of Hempcrete

Hempcrete is a much more superior building material due to the fact that it is a very strong, lightweight and breathable material.
