Build a Fire-Proof Home With Hemp Blocks

The Californian fires are devastating and no doubt families will want to rebuild what was lost. There is a lot of talk on social media platforms, like by investor Bill Ackman who is looking to invest in AI technologies to predict and help drones stop fires. But sometimes, vernacular building and sound ecological practices can save the day before technology, in a space called low-tech.

Fire hydrants and water packed drones might put out a fire if caught in time, but disaster-proofing your future might be a sound and sustainable move. Hemp blocks, also known as hempcrete are already on the market and are eco-friendly and sustainable construction materials composed of hemp, lime, and water.

What is hemp concrete?
Hempcrete or hemplime is biocomposite material, a mixture of hemp hurds (shives) and lime, sand, or pozzolans, which is used as a material for construction and insulation. It is marketed under names like Hempcrete, Canobiote, Canosmose, Isochanvre, and IsoHemp.I

In a recent study scientists look at the fire behaviour and structural performance of hemp-based materials in varying formats. They tested raw hemp shives, hemp blocks, and non-load-bearing hemp block walls.
