I love the idea of a hempcrete house. All the research I have done, tell me that it seems like a fantastic building material. However, for all of its suggested benefits, I am having trouble finding information (particularly videos) of people who have lived in a hempcrete house for a while. All the videos I find are about the construction process and the very beginning... nothing after, say 5 years, to see how things are holding up and if it lives up to the hype.

I'm sure a hempcrete house wouldn't be horrible, but there are always reality checks when living in naturally built houses or alternative materials, and I'm hoping to find out some of that information.

Anyone live in a hempcrete house? Know someone who does? Know of some videos done by someone who does?

Thanks in advance.

It continues to gain strength and harden over time (if done correctly) as it slowly absorbs more CO2 from the air. Senini Tecnocanapa in Italy has an unfinished demonstration wall at their plant that has been sitting in the elements for 7 years and it is as hard as stone! There is a little erosion on the top of the wall, but the rest of it is solid and flat. This material is based off historic materials like cob or Adobe that have been shown to stand the tests of time.

The lime binder is key to having a long lasting building, as the Romans have proven with their buildings that can be 2000 years old. The hemp Hurd is good but it can many different bioaggregates, like rice husk, wood, artichoke stalk even! We need to incorporate much more building and many more products to make monolithic biocomposite buildings out of waste forestry and agricultural resources, and create durable, healthy, energy-effixient and carbon sequestering homes.
