Assessing the Existing Infrastructure
Our initial walk-through of the site revealed advanced deterioration across all three basins. The walls of each unit had corroded substantially, and root intrusion was already beginning to choke off stormwater flow before it ever reached the storm system. We documented three distinct failure modes, each requiring full replacement rather than patch repair.
Structural Deterioration
Corrosion was undermining the long-term load durability of the basin walls. The structures were no longer rated to reliably bear sustained traffic loads from the parking lot above.
Flow Restriction
Live root growth had begun to throttle drainage capacity. Left untreated, this is the precursor to standing water in the parking lot during the next heavy rainfall and outright stormwater backups thereafter.
Surface Wear Indicators
Visible pavement settlement and asphalt wear directly above the basins were the surface-level evidence of an underground failure already well underway, the symptom most property managers notice first.
Catch Basin Failure Is Slow, Until It Isn't
Catch basin deterioration almost always develops gradually. In the early stages, corrosion or root intrusion only nibbles at drainage efficiency, the kind of issue that’s easy to deprioritize because it isn’t visible from the surface yet.
The problem is that those same conditions, given enough time, contribute directly to pavement settlement, persistent standing water after storms, and full storm system backups during heavy rain events.
Addressing failures proactively, during planned maintenance windows, is dramatically cheaper than addressing them reactively, after they’ve damaged the surrounding infrastructure, created a slip-and-fall liability, or triggered a compliance issue during a routine inspection.
The High Price of Ignoring Your Catch Basin
A full failure event triggers a cascade of costs. A planned replacement costs a fraction of any single one of them.
Potential Liabilities
Flooding in tenant & office spaces
Sewer backups
Sinkholes & ground collapse
Structural building damage
Health hazards & potential lawsuits
Total Potential Risk
The Smart Investment
A planned, preemptive catch basin replacement closes the entire risk window above for a tiny fraction of the worst-case cost.

Removal & Replacement
With the assessment complete, our excavation crew got to work pulling the compromised infrastructure and dropping in reinforced replacement basins built to restore proper stormwater performance and stand up to decades of parking lot traffic.
Saw Cutting & Site Access
Before any excavation begins, we use a precision concrete saw to score clean rectangular boundaries around each basin. This is what separates a controlled commercial repair from a destructive one.
Clean cuts mean the surrounding asphalt stays intact. The pavement that doesn’t need replacing doesn’t get torn up, which protects the property’s appearance and minimizes the area of new patch the client has to pay for.
Excavation & Removal
The compromised basin is removed in full, not patched, not lined. Surrounding sub-base is inspected and any failed material gets pulled out at the same time so we aren’t burying a future problem.
Reinforced Replacement
A new structurally-rated basin is set, connected to the existing storm tie-ins, backfilled in proper lifts, and the asphalt cap restored flush with the surrounding parking surface.
