Ground, water and winter in Bunker Hill
Draining in two directions helps, but water still finds the low spot in any driveway or lot. Clay-heavy soils common across the region hold it, and freeze-thaw winters push it back up through the pavement. We cut out soft subgrade, compact clean rock in layers, and set a grade that clears the surface before frost can work on it.
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 Bunker Hill estimate is sized to the soil, the traffic and the drainage on your property.
