Ground, water and winter in Oakland
This part of St. Louis County is rolling upland with clay-heavy soil, and mature tree cover keeps ground damp longer after a storm. Damp clay under thin asphalt is what produces the cracking and settling seen on older drives here. We take the soft material out, build base rock in compacted layers, and set a grade that clears water before it can freeze in place.
When you compare bids, ask each contractor for three numbers in writing: the compacted asphalt thickness, the base depth, and what happens to the water. Those three decide how long the surface lasts.
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 Oakland estimate is sized to the soil, the traffic and the drainage on your property.
