Why the base matters in Germantown
Clinton County ground here is farm soil that holds water, and the winters run through freeze and thaw repeatedly. Water that soaks under an edge lifts it when it freezes, then the surface cracks along the lift line. We grade for runoff, compact the base and keep the shoulders supported so the edges do not break down.
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 Germantown estimate is sized to the soil, the traffic and the drainage on your property.
