What's under a Alhambra driveway
Alhambra drains southwest toward Silver Creek, part of the Kaskaskia River watershed. Water that finds no path off a driveway soaks into the clay-heavy soils common in the St. Louis region, then freezes and heaves the surface in winter. We grade every job for runoff, remove soft material and compact the rock base 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 Alhambra estimate is sized to the soil, the traffic and the drainage on your property.
