Ground, water and winter in Detroit
Winters bring repeated freeze and thaw, and water that soaks into a weak base is what heaves and cracks pavement. Wet, soft ground loses strength, and a base built on it fails first. We check where water goes on your site, dig to firm ground, compact the base in lifts and set grades that move rain off and away.
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 Detroit estimate is sized to the soil, the traffic and the drainage on your property.
