Why the base matters in Pilot Knob
The knobs of the St. Francois Mountains are hard rhyolite, and the ground around them runs from rock near the surface to pockets of soft soil down in the valley. A base that works in one spot may not work forty feet away. We check the subgrade as we go, then compact rock in layers so freeze-thaw winters have less to work on.
Bids are only comparable when they spell out the same things: base depth, compacted thickness, how edges are finished, and where water is meant to go. Ask for those before you pick a number.

Typical ranges. Your Pilot Knob estimate is sized to the soil, the traffic and the drainage on your property.
