Ground, water and winter in Brentwood
The Deer Creek valley floor sits low, and its documented flooding history through the city tells you what water does here. Clay-heavy soils common around St. Louis hold what soaks in, and freeze-thaw winters lift pavement on a wet base. We plan drainage first, dig out soft subgrade and compact clean rock 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 Brentwood estimate is sized to the soil, the traffic and the drainage on your property.
