What's under a Glen Carbon driveway
Judys Branch runs just south of the village center and west toward the Mississippi River valley lowlands. Wherever water moves on your property, it needs a path off the pavement. The clay-heavy soils common around St. Louis hold moisture, and freeze-thaw winters heave a wet base. We grade first and compact the rock base in layers.
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 Glen Carbon estimate is sized to the soil, the traffic and the drainage on your property.
