The frame of the floor is made out of a PVC material. Each one of the legs sits on a rubber isolation pack. After the frame is sealed and isolated from the walls by isopreme, a rubber cement material is poored in and leveled. The arch of the floot is 13 cm, and with the filling the floors stand roughly 18 cm.
