Foundations and plinth
The foundations in a hempcrete building are much the same as in any other building,
serving to transfer the load of the building safely to the ground. Hempcrete's low density
allows some reduction of the amount of concrete used in some foundations, thereby redu-
cing the embodied energy of the build (most commonly, where the ground calls for a raft
foundation instead of the standard trench - see Chapter 12, pages 148 and 150 - 1). Free-
draining foundations can be very useful in hempcrete buildings, to reduce the potential for
moisture being held against the bottom of the hempcrete wall.
A good-sized plinth keeps the hempcrete wall in this new-
build house well above ground level.
