Why the base matters in Swansea
Swansea sits on largely flat ground, and flat ground drains slowly. Upland St. Clair County is covered in thick windblown loess silt that holds water once it is saturated, and freeze-thaw winters lift pavement built over it. We remove soft material, compact rock in lifts and set positive grade so water always has a way off.
Before you sign anything, get the base depth and the compacted asphalt thickness on paper. Two bids that look far apart are often just two different pavements.
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 Swansea estimate is sized to the soil, the traffic and the drainage on your property.
