Ground, water and winter in Crystal City
The city sits at the edge of the Mississippi River floodplain, so bottom ground stays wet and settles while ground above it drains faster. Jefferson County soils also run to clay that swells and shrinks. Freeze-thaw winters lift water trapped in a base. Drainage and compaction come before paving.
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 Crystal City estimate is sized to the soil, the traffic and the drainage on your property.
