Ground, water and winter in Dorchester
Drainage east toward the creek helps, but a flat drive or a low lot will still hold water. Clay-heavy soils common across the region keep it there, and freeze-thaw winters push it up through the surface. We grade for runoff first, then remove soft subgrade and compact clean rock in layers before any asphalt goes down.
A cheap bid usually gets cheap somewhere you cannot see. Ask what depth of stone goes down, how thick the asphalt is after rolling, and who fixes it if water still stands.
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 Dorchester estimate is sized to the soil, the traffic and the drainage on your property.
