Why the base matters in Ellisville
The neighborhoods off Kiefer Creek Road sit on rolling loess upland over limestone, typical of this side of the county. The county soil survey says local streets here need adequate base plus side ditches and culverts to prevent damage from low strength and frost action. We grade for runoff, compact in layers, and keep water off the edges.
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 Ellisville estimate is sized to the soil, the traffic and the drainage on your property.
