What's under a Brewer driveway
Perry County is karst country, with more than 680 known caves, and sinkholes, springs and losing streams tie surface runoff straight to shallow groundwater. Water travels where you cannot see it, and soft spots follow. We look at drainage before thickness, dig out weak subgrade and compact clean rock in layers before paving.
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 Brewer estimate is sized to the soil, the traffic and the drainage on your property.
