Shuttering - The Hempcrete Topic: Designing and Building with Hemp-lime - page 276

For this building the whole of the outside was shuttered in advance, then the
hempcrete placed from inside.
In the cast-in-situ method, hempcrete is cast around a frame on-site, with the aid of
shuttering boards, which keep the freshly mixed hempcrete in place while it sets.
Shuttering may be either temporary or permanent.
