Ground, water and winter in Frontenac
Rolling hills and mature trees mean runoff has somewhere to go, but it also means slopes that cut and low spots that hold. The county soil survey calls for adequate base plus side ditches and culverts to prevent damage from low strength and frost action on these loess uplands. We grade for that 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 Frontenac estimate is sized to the soil, the traffic and the drainage on your property.
