Built for Valmeyer's ground
Much of upland Monroe County is sinkhole plain, where loess, till and bedrock residuum sit over creviced limestone, and the Illinois State Geological Survey advises examining ground carefully before building on it. We check drainage and soft spots before setting base, compact rock in lifts, and grade so water leaves the surface instead of soaking down.
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 Valmeyer estimate is sized to the soil, the traffic and the drainage on your property.
