What's under a Hartford driveway
The Cahokia Creek Diversion Channel runs through the southern part of the village, a reminder that all of this ground is managed water. Bottom soil holds moisture, and moisture under asphalt freezes and lifts in winter. We build the grade to drain, compact the base in layers and keep the edges supported.
A cheap bid usually gets cheap somewhere you cannot see. Ask what depth of stone goes down, how thick the asphalt is after rolling, and who fixes it if water still stands.
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 Hartford estimate is sized to the soil, the traffic and the drainage on your property.
