PTC – Ballasted Columns – Top Feed
Stone columns “Top Feed Method” is the more cost-efficient ground improvement method. It requires the use of a free hanging vibrolance that penetrates the ground thanks to the lateral vibrations emitted by its tip. During penetration, the soil is laterally compacted by displacement, allowing the vibrolance to create the hole that will contain the stone column.
