Ground, water and winter in Dardenne Prairie
The county soil survey notes upland soils here with clayey subsoil that swells and shrinks with moisture, and some that lack strength for traffic until crushed rock goes into the base. Freeze-thaw winters find every weak spot. We grade for runoff and compact the rock in layers rather than dumping it in one lift.
Before you sign anything, get the base depth and the compacted asphalt thickness on paper. Two bids that look far apart are often just two different pavements.
Compacted asphaltTypically 2 to 3 in. for a car drive
Stone baseTypically 4 to 8 in., compacted
Drive on itUsually 2 to 3 days, longer in heat
First sealcoatTypically 6 to 12 months after paving
Typical ranges. Your Dardenne Prairie estimate is sized to the soil, the traffic and the drainage on your property.
