- Photo + GPS documentation per reading
- Closes coating warranty files credibly
Typical assets
How it works
- 1
Specification review
The coating spec defines required DFT and measurement standard — the survey is built to verify exactly that.
- 2
Aerial measurement
Magnetic induction on ferrous, eddy current on non-ferrous substrates — the probe contacts and records automatically.
- 3
Statistical coverage
Readings across all elevations and orientations — the high, awkward areas where coating failures actually start and manual checks never reach.
- 4
Compliance report
Per-point values, statistics against specification, and GPS-tagged photos — the document the applicator, owner, and warranty all reference.
Frequently asked
Why measure coating thickness at height instead of just at grade?
Because failures start where application was hardest — tops of tanks, upper stack sections, bridge members over water. Grade-level readings systematically miss the highest-risk areas. Aerial DFT samples the whole asset, which is what a credible warranty or QA file requires.
Which standards do your DFT surveys follow?
Surveys are run to the measurement practice your specification cites — SSPC-PA 2 conventions for acquisition and averaging are the common default. Instrument class covers 0–1.5 mm on ferrous and 0–0.7 mm on non-ferrous substrates.
Can this resolve a dispute with our coating contractor?
It usually settles it one way or the other: hundreds of GPS-tagged, photo-documented readings against the spec leave little to argue about. Both owners and applicators hire us for exactly that neutrality.
Do you measure DFT on bridges and infrastructure?
Yes — bridge steel, transmission structures, stacks, and tank farms are the core use cases. Anywhere the alternative is lane closures, lifts, or rope teams, the aerial economics win quickly.
