What's under a Castle Point driveway
North County sits on rolling upland with the clay-heavy soils common around St. Louis. Clay holds water, then swells and shrinks with the seasons, and pavement laid over it cracks. Freeze-thaw winters widen those cracks into potholes. We fix drainage and compact the base before any asphalt goes down.
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 Castle Point estimate is sized to the soil, the traffic and the drainage on your property.
