Why?
This question assumes that hard ground has sufficient bearing capacity without additional pads. On soft ground, outrigger pads (podkłady pod podpory) spread the load over a larger area, so they should not be omitted. In practice, surface hardness alone is insufficient: assess the ground's bearing capacity and follow the manufacturer's instructions.
