Reservoir & Dam Seepage Detection in North Vancouver, BC
Thermal and visual reconnaissance of earthen dams, dikes, reservoirs, and embankments — seepage exit points, wet zones on downstream faces, and anomalous vegetation mapped without crews walking unstable slopes. Flown by Transport Canada-certified RPAS pilots and confirmed by the ground crews serving North Vancouver and the Metro Vancouver region — since 1999 as BC's leak detection specialists.

Flying North Vancouver: local context
Port terminals, shipyards, and slope-side mid-rises — marine-industrial assets meet mountain weather windows.
Local property profile: Steep-lot homes with long private service runs, creek-adjacent properties, and mid-rise growth around Lonsdale.
Ground conditions: Coarse till scans cleanly until bedrock ends penetration — often within 1–2 m on upper slopes. Services squeezed into that shallow band image sharply.

How the North Vancouver survey runs
- 1
Structure briefing
Drawings, prior inspection reports, and known wet areas frame the survey. We coordinate with the owner's dam-safety engineer so the data lands inside their existing surveillance program.
- 2
Thermal face mapping
Groundwater and seepage water hold a stable temperature year-round while surfaces swing with the weather — exit points and wet zones contrast clearly in the right window. The full downstream face, abutments, and toe are mapped in one flight.
- 3
Visual + vegetation pass
High-resolution visual imagery captures the classic secondary indicators: preferentially green vegetation strips, cattail colonisation, soft-ground texture, and animal-burrow activity along the toe.
- 4
Georeferenced report
Thermal anomalies and visual indicators plotted on the structure, compared against any previous survey, and delivered in a format your engineer-of-record can take straight into the surveillance file.
North Vancouver questions, answered
How does thermal imaging find seepage on a dam?
Seepage water originates underground, where temperature is stable — roughly 8–12 °C in much of BC — while the embankment surface follows air temperature. In warm weather a seep reads cold against the face; in cold snaps it reads warm. Flown in the right contrast window, exit points and saturated zones stand out measurably, including early-stage wet areas a walking inspection can miss.
Does this replace our dam safety inspections?
No, and we will not pretend otherwise. BC dam owners operate under the Dam Safety Regulation with defined surveillance obligations run by their engineer-of-record. What we provide is reconnaissance data — full-face, repeatable, georeferenced — that makes those inspections better targeted, and a safe way to look at faces and toes that are hazardous to walk.
Can you survey dikes and flood embankments too?
Yes — linear flood-protection works are ideal drone subjects: long, uniform, and tedious to walk. Kilometres of dike face and toe are mapped per flight day, with anomalies geotagged for follow-up. Post-freshet and post-storm baselines are the common triggers in BC.
Can you legally fly drone leak surveys in North Vancouver?
Yes — our pilots hold Transport Canada RPAS certification with advanced-operations capability, and North Vancouver flights run under whatever airspace authorizations the location requires. Port terminals, shipyards, and slope-side mid-rises — marine-industrial assets meet mountain weather windows. Flight planning, NOTAM checks, and authorizations are part of the service, not your problem.
How do North Vancouver ground conditions affect what the survey reads?
North Vancouver ground is predominantly coarse till and colluvium over shallow bedrock on the mountain slopes. Coarse till scans cleanly until bedrock ends penetration — often within 1–2 m on upper slopes. Services squeezed into that shallow band image sharply. For buried-leak work that matters: escaping water changes the moisture and thermal behaviour of exactly that ground, and our analysts interpret the surface signal against the local soil character — then our acoustic ground crews confirm the suspect zones before anyone digs.
What does reservoir & dam seepage detection cost in North Vancouver?
Province-wide pricing — no regional premium for North Vancouver. Single-site surveys typically start in the high hundreds; network corridors, portfolios, and multi-asset programs are quoted by scope. The free phone consult (604-239-9934) produces a firm number in about five minutes.
