What's under a Salem driveway
Town Creek runs through the east side of Salem toward Crooked Creek, part of the Kaskaskia River watershed. Properties near it, and flat lots anywhere in town, need drainage planned before paving. Slow-draining soils are common in this part of Illinois, and winter freeze-thaw turns trapped water into cracks, so we build on compacted base and grade every surface to shed rain.
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 Salem estimate is sized to the soil, the traffic and the drainage on your property.
