JustBioFiber is a company that has found a solution to many of hemp’s shortcomings when it comes to building. While “hempcrete” alone can’t be loadbearing, the epoxy block centers give the hemp structural integrity. It also makes it easy to run electrical wires inside the blocks.
As you can imagine from the pictures, building with these hemp blocks is easy! And the results? Strong homes that retain heating or cooling because of their high R-values. The blocks are a mixture of hemp core (from the stalk of the plant) and lime. You can plaster the interior and exterior for a smooth finish. What do you think?

This certainly works though one had better be good at plastering as a lot of it. Would go up fast for a DIY though.
I was hoping for a SIP like hemp fiber boards with insulation in between.
I hope SIPES is in the near future as it would work on mobile trailer frames and abundance of those available, weight is the issue.
