EMAT Inspection in Delta, BC
Electromagnetic acoustic transducer thickness testing by drone — no couplant, up to 4 mm lift-off, made for corroded, dirty, or coated steel where conventional UT struggles. Flown by Transport Canada-certified RPAS pilots serving Delta and the Metro Vancouver region — since 1999 as BC's leak detection and inspection specialists.

Flying Delta: local context
Tilbury industrial lands, port logistics, and greenhouse country — big roofs, big tanks, long lines.
Local asset profile: Agricultural parcels with decades of private piping, Tsawwassen slab-on-grade subdivisions, and port-industrial lands.
Typical emat inspection work around Delta
- Greenhouse energy-loss scans
- Port logistics roof programs
- Corroded or scaled tank shells
- Coated structures without coating removal
- Dirty industrial surfaces
How the Delta survey runs
- 1
Surface review
Coating type and condition assessed — EMAT is selected precisely where scale, dirt, or coatings would slow conventional UT.
- 2
Aerial scan
The EMAT head generates ultrasound electromagnetically in the steel itself — contact without couplant, tolerant of rough surfaces.
- 3
Grid acquisition
Readings collected on the survey grid at production pace; anomalies densified immediately.
- 4
Screening report
Thickness map with flagged zones — often the triage step that targets follow-up quantitative UT exactly where it pays.
Delta questions, answered
How does EMAT work without couplant?
EMAT generates the ultrasonic wave electromagnetically inside the conductive material rather than transmitting it through a gel interface. No couplant, no surface wetting, and tolerance for up to 4 mm of lift-off — which is why it shines on scaled, dirty, or coated steel that would need grinding before conventional UT.
When do you choose EMAT over standard aerial UT?
When surface preparation is the bottleneck: heavy scale, old coatings, dirty process environments, or screening programs covering large areas fast. Conventional UT still wins for highest-precision spot measurements on prepared surfaces — many programs use both, EMAT to screen and UT to quantify.
What materials can EMAT inspect?
Conductive metals — carbon steel is the everyday case, per ASTM E1816-18 practice. Range 2–150 mm with 0.06 mm resolution covers everything from thin shell plate to heavy structural sections.
Can EMAT find corrosion under paint without damaging it?
Yes — that is one of its best tricks. Reading through intact coatings means corrosion surveys no longer require destroying the coating you are trying to protect. Where the coating itself is the question, we pair it with aerial DFT measurement.
Can you legally fly drones for inspection in Delta?
Yes — our pilots hold Transport Canada RPAS certification with advanced-operations capability, and Delta operations run under whatever airspace authorizations the location requires. Tilbury industrial lands, port logistics, and greenhouse country — big roofs, big tanks, long lines. Flight planning, NOTAM checks, and authorizations are part of the service, not your problem.
How does Delta weather affect scheduling?
Aerial inspection flies in defined weather windows — wind, precipitation, and (for thermal work) the right temperature differentials. Delta sits in our standing Metro Vancouver coverage, so we schedule against the local forecast and typically land the survey within days of booking rather than weeks. Mon–Sat, 8am–6pm Pacific.
What does emat inspection cost in Delta?
Province-wide pricing — no regional premium for Delta. Single-asset thermal surveys typically start in the high hundreds; NDT campaigns and multi-asset programs are quoted by scope. The free phone consult (604-239-9934) produces a firm number in about five minutes.
