Ground, water and winter in New Baden
Clinton County is a nearly level loess-covered till plain, and many of its silty soils are poorly drained with a seasonal high water table within a few feet of the surface. Flat ground and a high water table mean base preparation and drainage carry the job. We grade to move runoff, dig out soft material and compact the base in layers.
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 New Baden estimate is sized to the soil, the traffic and the drainage on your property.
