Why the base matters in Wilmington
Northwest Greene County ground holds moisture in its silty soils, and saturated base material under a hard freeze lifts and cracks asphalt. The fix is drainage, built in from the start. We grade the surface to an outlet, compact rock in layers and keep the edges supported so runoff cannot undercut them.
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 Wilmington estimate is sized to the soil, the traffic and the drainage on your property.
