Ground, water and winter in Rentchler
Upland ground east of the Mississippi bluffs is capped with deep windblown loess silt, which holds water and heaves when it freezes. Pavement over silt lives or dies on drainage. We take out soft material, compact base rock in layers, and set the grade so runoff leaves instead of soaking under an edge.
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 Rentchler estimate is sized to the soil, the traffic and the drainage on your property.
