Ground, water and winter in Summerfield
Upland St. Clair County sits under thick windblown loess silt, which compacts well but holds moisture when it is not drained. Freeze-thaw winters then lift anything built over a wet base. We strip soft material, compact rock in lifts and set the grade so water runs off the pavement rather than collecting along the edges.
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 Summerfield estimate is sized to the soil, the traffic and the drainage on your property.
