Why the base matters in Coalton
Coalton drains northwest toward the East Fork of Shoal Creek, part of the Kaskaskia River watershed. Where ground is flat, water moves slowly and slow-draining soils can stay wet under pavement. We cut out soft areas, build up firm compacted base, and grade so rain leaves the surface quickly, before winter freeze-thaw can turn it into cracks.
When you compare bids, ask each contractor for three numbers in writing: the compacted asphalt thickness, the base depth, and what happens to the water. Those three decide how long the surface lasts.
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 Coalton estimate is sized to the soil, the traffic and the drainage on your property.
