SAVE (Silent, Advanced Vibration-Erasing) Compozer, a Non-Vibratory Replacement (soil densification) method, has been born by the development of a rotary penetrating system for wave-type implementation that uses a new type of forced driving / lifting device. This allows densification of subsurface soils adjacent to the existing buildings, and significantly widens the applicable area for the densification. Various materials such as stone, sand, crushed concrete, or slag can be used as filling materials for this method.
