Why the base matters in Gorham
Floodwater has reached this village more than once, including 1993 and the New Year's flood of 2016, and bottomland stays wet longer than upland ground. A wet base plus a freeze is what heaves a surface. Drainage comes first on every job: grade the surface, compact the base, keep water moving.
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 Gorham estimate is sized to the soil, the traffic and the drainage on your property.
