Why the base matters in Berger
Missouri River bottomland holds moisture and settles unevenly, and Franklin County's uplands nearby carry loess over cherty clay. Neither drains fast. Add freeze-thaw winters and any pavement on a wet base will move. We keep the water moving off and out: graded surfaces, ditching where needed, rock compacted in layers.
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 Berger estimate is sized to the soil, the traffic and the drainage on your property.
