What's under a Vandalia driveway
The Kaskaskia River runs through this part of Fayette County, and the flat farm ground around it drains slowly. Clay-heavy soils common across the region hold water rather than passing it along, and freeze-thaw winters lift pavement built on a wet base. We remove soft soil, compact rock in lifts and set grade so water sheds.
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 Vandalia estimate is sized to the soil, the traffic and the drainage on your property.
