Ground, water and winter in Roxana
The river bottoms on this side of Madison County are deep river-laid clay, silt, sand and gravel behind the levee system, and ground like that holds water and can be soft under load. We proof the subgrade, remove what will not compact, build the rock base in lifts, and grade so water leaves the surface.
Bids are only comparable when they spell out the same things: base depth, compacted thickness, how edges are finished, and where water is meant to go. Ask for those before you pick a number.
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 Roxana estimate is sized to the soil, the traffic and the drainage on your property.
