Hempcrete is ten times stronger than concrete, mold resistant, rot resistant, pest resistant, fire resistant, and carbon negative. It’s even better than cob/adobe.
I’ve written before about how cob or “adobe” is the best building material on earth… and it was… until hempcrete.
Ten times stronger than concrete, and one sixth the weight, this amazing all-natural material is made of nothing but hemp pulp, lime binder and water.
Like cob, it’s non-toxic, super insulating, termite-resistant, fire-resistant, mold-resistant, rot-resistant, “breathable” and will last for hundreds of years.
Unlike cob, it has the added benefit of sequestering massive amounts of carbon from the atmosphere.
While the hempcrete is a new phenomenon to most of us alive today, archaeologists believe a similar technology was used as far back as ancient Egypt, a French architect says in the mini documentary below.
In the documentary, Clarke Snell of the Nauhaus Institute discusses one of hempcrete’s best features — it’s breathability.
