What's under a Gray Summit driveway
This is the northern edge of the Ozarks, where cherty red clay over dolomite is common and karst features like sinkholes and springs show up. Clay holds water, and a wet base under freeze-thaw winters is what destroys pavement. We remove soft soil, compact rock in layers and grade so runoff leaves.
The part of the job you can see is the last two inches. Ask what is underneath, how it will be compacted, and which way the finished surface drains.
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 Gray Summit estimate is sized to the soil, the traffic and the drainage on your property.
