What is Skin-Friction?

Skin-Friction is the soil resistance acting along a pile shaft, caused by soil moving
relative to the pile shaft; it must be less than, or equal to, the shaft capacity.
Negative skin friction – Soil resistance acting downward along a pile shaft,
caused by soil moving downward relative to the pile shaft.
Positive skin friction – Soil resistance acting upward along a pile shaft, caused
by soil moving upward relative to the pile shaft
