Hempcrete - A revolutionary building material!
As the world shifts towards resilient living, permaculture design and reducing carbon footprints, innovative building materials are (re)emerging to transform the construction industry. One such game-changer is Hempcrete!! – a natural, durable, and eco-friendly material made from hemp fibers and lime.
What is Hempcrete?
Hempcrete is a bio-composite material created by mixing hemp fibers (shiv) with a lime-based binder. This unique blend provides exceptional insulation, breathability, and strength while striving for a carbon-negative building.
Benefits of Hempcrete
Many benefits for resilient construction, passive houses, barns, community centers, schools, gov’t buildings tec. - Hempcrete's Carbon Sequestration Power:
Hemp absorbs CO2 during growth, and Hempcrete stores it permanently – making it a carbon-negative material! This means that buildings constructed with Hempcrete can actually reduce carbon dioxide levels. Bam.
Hempcrete in Action with Friends
Mmixing 1 part hemp shiv (hemp fibers) with 2 parts lime-based binder and 2 parts water in a large bucket. Stir until the mixture resembles wet cement. Then, fill a mold (you can use a wooden frame or plastic container) with the hempcrete mixture and compress it using a tamping tool or your feet! Let it set for 24 hours, then demold and cure the brick in a dry, cool area for 2-4 weeks. Share laughs, food, stories, repeat.
Superior Insulation and Breathability
Hempcrete provides excellent thermal mass, reducing heating/cooling needs by up to 70%. Its breathable nature allows moisture transfer, preventing mold and mildew growth – ensuring a healthier indoor environment for occupants. A great building alternative for here in the PNW and other mold-prone environments.
Durability and Sustainability
Hempcrete is resistant to pests, rot, and fire – lasting centuries with minimal maintenance. Additionally, hemp is a fast-growing, renewable crop requiring minimal water and pesticides, making it a highly sustainable source material.
