Why the base matters in Bellerive Acres
Loess upland over clay runs through north St. Louis County, and the county soil survey calls for adequate base plus ditches and culverts on many local roads because of low strength and frost action. Water that sits under asphalt through a freeze will lift it. We grade to shed and compact rock in layers.
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 Bellerive Acres estimate is sized to the soil, the traffic and the drainage on your property.
