Can the normal setting depths be reduced if setting in solid rock?

When you’re setting something into the ground, the depth you embed it to is chosen to make sure it can safely resist the loads. Solid rock acts very differently from soil—it has much higher strength and can grip and transfer loads effectively. Because of that, you don’t need as much embedment depth to achieve the same holding capacity. In practice, this often means you can reduce the normal setting depth to a fraction of what you’d use in soil, and the standard cited here is a reduction to about 10%. This reflects the rock’s superior resistance to pullout and movement compared to soil. Of course, always follow the specific manufacturer's guidelines and site conditions, but the general principle is that solid rock allows a shallower embedment than in looser ground.
