Yes. Hempcreate is supposed to be used between the interior and exterior concrete walls because it's insulating and less expensive (can be mixed onsite). This combined with rebar allows it to function for purpose. Because the exterior layers of concrete is bearing the load around the hempcreate and the reinforced hempcreate provides rigidity and anchor to the foundation, it's complimentary. Which saves money on the fill and is also insulating. In turn, removing the hemp from the weather and expansion cycles. The expansion cycles, I'd guess, would be the point of failure of any attempt to directly use it solely structurally. I had no idea anyone was using it for the entire structure.
