What's under a St. Johns driveway
Flat ground with some rolling hills means water sits before it moves. Clay-heavy soils common across this region hold that water, and freeze-thaw winters push it back up through anything resting on a soft base. We dig out weak spots, compact rock in layers and shape the surface so rain runs off instead of soaking in.
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 St. Johns estimate is sized to the soil, the traffic and the drainage on your property.
