Vibration-based method and system for densification of ground soil, method comprising the steps of providing a draining unit, comprising a drain installation, at a depth in the ground soil and providing a vibration unit, determining one or more ground soil locations for applying vibration to the ground soil based on a position of the draining unit, and extracting fluid from ground soil using the drain installation while at least during an overlapping period of time applying vibration with the vibration unit to the one or more ground soil locations in order to densify the ground soil. Unlocking insights from Geo-Data, the present invention further relates to improvements in sustainability and environmental developments: together we create a safe and liveable world.
