The vertical penetration of the ball into a soft clay seabed causes a heave of soil adjacent to the ball. The soil weight contributes an additional component of vertical resistance, exceeding simple buoyancy (F b = f b γ′V B, f b = 1.0) due to the distorted geometry of the soil surface.

Ball clay extraction involves mining techniques such as dredging, where the clay is extracted from the bottom of rivers or lakes, or open-pit mining, where the clay is excavated from the surface using heavy machinery.
