Hi,The mix design we use as Hempcrete wouldn't be of use in this manner. The mix density is 275kg / m3 - I believe it would be prone to compaction. We have used beneath a lime screed where the dense solid screed topping distributes point loads - Unlike other comments on the web I don't consider Hempcrete to be stronger than concrete. In our use it does produce a robust insulating section to receive Render / Plaster or screed finishes. Limecrete [Lime Concrete] may however be viable.
Is Hempcrete suitable for construction of roads and sidewalks? I understand that Hempcrete insulates heat, making it less prone to cracking from thermal variation.
