What's under a Crystal Lake Park driveway
West County sits on rolling upland over the clay-heavy soils common around St. Louis. Clay swells when wet, shrinks when dry, and pavement above it cracks along the same lines year after year. Tree cover keeps ground damp, and freeze-thaw winters lift trapped water. Drainage and compaction decide the outcome.
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.
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 Crystal Lake Park estimate is sized to the soil, the traffic and the drainage on your property.
