Expanded clay replaces the three standard layers of insulation. As the media is evenly distributed (on even on uneven ground), you do not need to have a sand bed. The low density of expanded clay constitutes a sufficiently stable ground under the floor, so you can dispense with the concrete base. Furthermore expanded clay as a ceramic material has the ability to accumulate heat from the room and overcome the adverse impact watercourses.
