1,200 sq ft driveway replacement with broom finish and reinforced apron for a Prescott Lakes home.
The problem
The original 1998 driveway had failed at the apron where snowplow loads had cracked through to the sub-base. Freeze-thaw had spalled roughly 30% of the surface, and drainage was running back toward the garage slab.
Our approach
- Sawcut and remove existing 4-inch slab plus failed sub-base
- Regrade for 1.5% slope away from garage, correcting the original drainage error
- Import and compact 6 inches of class II road base in two lifts
- Set rebar grid on 18-inch centers with chairs, thickened edge and apron to 6 inches
- Pour 4,500 PSI air-entrained mix, 5.5% air content
- Broom finish with cut control joints every 10 feet, sealed at 28 days
Materials & specs

Outcome
Delivered on schedule and $600 under estimate after we reused the original apron cut for base fill. First winter passed with zero spalling and clean drainage across the pad.
"They pulled a permit the same week we signed and had it done before Memorial Day. The drainage fix alone was worth the price."
