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.

Hemp cannot make you feel “high” and actually provides a healthier air quality than current building materials used. According to Danny Gough of Energy Solutions, (WSJ HomePlace 01/12/14), in a recent report released by the Healthy Building Network, researchers looked into over 1,300 ingredients found in common building products and identified 38 chemicals that can cause asthma…Hempcrete is an all-natural mixture of hemp hurds, a lime binder, and water. This material actually emits oxygen and inhales carbon dioxide, due to the lime petrification process! Although hemp can be used in the walls, roofs, and floors of your house, homeowners should still be aware of harmful chemicals found in carpets, paints, varnishes, adhesives, and countertops.
