Specifications
Prior to rehabilitation, the Monroe, Michigan Walgreen’s parking lot was worn and cracked from weather and high-volume retail traffic, particularly showing severe deterioration around catch basins.
After careful evaluation and inspection, D&J recommended a targeted partial rehabilitation rather than full demolition, extending surface life by up to 8 years and generating $50,000 in immediate savings.

Operational Flow
Phased Execution Plan
Our diagnostic approach evaluated structural root causes, delivering targeted repairs that protected the client’s capital budget.
01
Site Evaluation & Inspection
Conducted detailed core testing and subbase analysis. Rather than advising a full teardown, D&J proved that strategic base stabilization and partial rehabilitation would restore structural integrity.
02
12" Base Removal & Full-Depth Patching
Excavated failing asphalt and soft underlying soils up to 12 inches deep in high-load drive lanes. Backfilled with aggregate base and compacted to commercial compaction standards.
03
Catch Basin Rebuild & Sidewalk Upgrades
Demolished cracked brick/mortar catch basins and poured heavy-duty concrete collar assemblies to stop water intrusion beneath the asphalt. Replaced damaged concrete walkways.
04
Asphalt Overlay, Seal Coating & Line Striping
Applied high-grade commercial asphalt, sealed the entire lot against UV and moisture penetration, and applied crisp line striping for retail traffic and pedestrian safety.
