Commercial Stormwater & Site Drainage Leak Investigation
When a commercial site floods, ponds, or undermines pavement after rain, the cause is usually a failed storm drain, catch basin or area drain — not the sanitary system. We investigate site stormwater and drainage with CCTV, dye and tracer testing, locate the break or blockage, and document it for targeted repair, without trenching the site to find it.
Stormwater failures on commercial sites
Storm systems carry surface and roof water away from the property. When a storm main, lateral, catch basin or area drain fails, water backs up, ponds, undermines pavement, or escapes into the ground. Distinguishing a storm failure from a sanitary issue is the first step.
What we investigate
We cover the full site stormwater network:
Storm mains & laterals
Cracked, offset or collapsed storm piping.
Catch basins & area drains
Failed sumps, connections and grates.
Sub-surface & perimeter drainage
Failed weeping tile and foundation drainage.
Methods we combine
Drainage investigation calls for camera and tracer techniques:
Locating the break for targeted repair
We locate the camera at the defect from the surface so the repair is a single targeted dig, and we document the condition for engineers and municipalities.
Detection methods we use
CCTV camera inspection
Sees inside storm mains, laterals and drains to find cracks, offsets and collapses.
Dye testing
Confirms flow paths and storm/sanitary cross-connections.
Sonde locating
Marks the defect position on the surface for targeted excavation.
Smoke / tracer
Reveals hidden connections and breaks in the drainage network.
Where this applies
- Commercial plazas, retail and office sites
- Strata and multi-family site drainage
- Institutional and campus grounds
- Industrial yards and loading areas
What you receive
- Located break, blockage or collapse
- CCTV evidence of pipe condition
- Storm-vs-sanitary confirmation
- Report for engineers and municipalities

Frequently asked questions
Storm vs. sanitary — can you tell which?
Yes. Dye and tracer testing plus CCTV confirm which system is failing and whether there is a cross-connection.
Can you locate a collapsed storm line?
Yes. CCTV finds the collapse and sonde locating marks its exact position on the surface for targeted repair.
Do you CCTV and locate in one visit?
In most cases yes — we camera the line and locate the defect in the same investigation.
Can you dye-test to confirm cross-connections?
Yes. Dye testing reveals improper storm/sanitary cross-connections and hidden flow paths.
What report do engineers get?
A report with the located defect, CCTV evidence and condition assessment for civil engineers and municipalities.
