Prof Kris Dick at the University of Manitoba is working on hempcrete so must be sourcing its components (umanitoba.ca). Hemp is grown and processed in the Canadian Prairies, but I am not sure all the other components of hempcrete are easily found in North America. I think there is a company in North Carolina developing and marketing hempcrete, they too may be bringing in some product (the particular lime perhaps) from the UK. <BR>

Hello Jason and all,
<BR>
<BR>
So I poked around in my old straw bale connections and the guy I used to buy hemp hurds from, which we added to the plaster mix to reduce cracking, is no longer around. Moved out west. So that's a dead end unfortunately. I do however remember someone having hemp blocks at Greenbuild when it was in Toronto, but for the life of me, I can't find the company propaganda anywhere in my office. I googled and couldn't find it either. I did find a hemp insulation company. I have one of their sample batts, lovely stuff, nice and stiff and pleasant. <A HREF="http://www.memvegetal.com">http://www.memvegetal.com</A> The website is all in French, so you might need to run it through the translator, but neat stuff.
<BR>
<BR>
There was talk of trying to get Durisol to use hemp, but I don't know where that went. Also Hebel would be another to consider as they use natural materials too.
<BR>
<BR>
I suspect that the majority of any of these items, if available, would be difficult to ship to the US, especially the raw material due to your laws. I don't know though.
<BR>

I did work on one straw bale house where we built with hemp bales. If anyone is considering it, I would strongly advise against it, simply because those stalks are very strong. For those who have played with bales, know you cut it open, and retie to make a smaller bale by separating the "flakes". This doesn't work with hemp, as the stalks are 8+ feet long, and so you drag and try to cut (very hard to cut) and curse and make a general mess. Never again.
<BR>
<BR>
Sorry I couldn't be more help.
<BR>
<BR>

Hi Stephen,<BR>
<BR>
Most likely looking for blocks to be stacked. But if there are leads on raw<BR>
hulls and formulas for making the blocks, it could be very useful, too.<BR>
Thanks.<BR>
