Holding power comes from how well the surrounding material resists being pulled out and how it provides friction and bearing support around the anchor. Crushed rock can be compacted into a dense, interlocked base around the anchor, creating a stable, high-friction environment that resists pull-out effectively. Water would wash away or reduce friction and also erode support. Soil can vary in density and cohesion, often offering less predictable resistance, and sand tends to be loose and can shift or migrate under load, giving much weaker resistance. So crushed rock provides the strongest, most reliable holding power for anchors.
