Concrete Scanning in Iqaluit, NU
Scan the slab before you core, cut, or drill.
Locating companies offering Concrete Scanning in Iqaluit and the surrounding Qikiqtaaluk area. One short request, competing quotes, no phone call required.
Concrete Scanning brings a specific capability to Iqaluit: High-frequency ground penetrating radar run across a structure rather than the ground, mapping rebar, post-tension tendons, conduit, and voids inside the concrete. It is done immediately before a penetration so the crew knows where it is safe to cut. For construction and municipal work across Qikiqtaaluk, it is frequently the right instrument for the question being asked.

Soil, moisture, and radar around Iqaluit
Ground around Iqaluit runs to permafrost and rocky. Rocky ground does not so much absorb the radar pulse as scatter it. Cobbles and fractured rock return reflections of their own, and the real difficulty becomes telling a pipe apart from a boulder. Ground like that does not stop radar so much as complicate reading it, so an operator’s experience with this profile counts for as much as the equipment does. Electromagnetic tracing confirms whatever is conductive, and a vacuum-excavated test hole settles what the surface methods leave ambiguous. Nunavut frost reaches roughly 144" around Iqaluit, and potable water services are set below that line, so water runs here sit deeper than the same lines would in a warm state and further from what a surface instrument can confirm on its own. Gas, electric, and communications are not frost-governed and are routinely far shallower, often inside the first two feet, and sewer depth follows the fall the pipe needs rather than the frost line. Iqaluit sits in a cold subarctic climate, and soil moisture is what moves radar performance from one part of the year to the next. Marks are temporary in any case, and paint on turf can disappear within days once mowing resumes, so any site here that will be dug more than once is usually worth mapping rather than re-marking.
What Concrete Scanning is used for in Iqaluit
- Core drilling for plumbing, electrical, and conduit penetrations
- Saw-cut openings for stairs, elevators, shafts, and floor drains
- Anchor and dowel drilling into slabs, decks, walls, and beams
- Clearing penetrations in post-tensioned slabs before any cut
- Locating conduit and radiant heat tubing in existing floors
- Confirming rebar layout and cover before demolition or retrofit
- Void and delamination detection in slabs, decks, and walls
What Concrete Scanning finds in Iqaluit
Before you dig in Iqaluit
Every dig in Iqaluit starts the same way: a locate request to Nunavut Locates (1-867-975-5400). It is free, it is required by law before excavation in most jurisdictions, and it is the only mechanism that tells the facility owners to come out at all. They will mark from the main up to the meter, the pedestal, or the edge of the right-of-way. Nunavut requires permits and locates from local hamlet councils; continuous permafrost changes how radar and electromagnetic locating perform, and piped services are commonly carried in above-ground utilidors or in shallow insulated, heat-traced trenches rather than below the frost line.
Past that point the lines belong to the property owner, and Nunavut Locates does not mark them. On a community site that usually covers the building service, yard and parking lot lighting, irrigation mains and controller wire, sewer or septic laterals, private fire loops, and communications runs between buildings. A private locating company sweeps that side of the site with electromagnetic tracing and radar and marks it in APWA colors, on top of the Nunavut Locates ticket and never as a replacement for it.
Questions
Concrete Scanning in Iqaluit FAQ
What happens if a core drill cuts a post-tension cable?
A stressed tendon holds tens of thousands of pounds of force, and cutting one releases that energy violently at the point of the cut and at the anchor, which can injure anyone nearby. With unbonded monostrand, the loss runs the full length of the tendon, so the slab loses the precompression that strand provided across the whole span rather than just at the hole; with grouted, bonded tendons the force redevelops through bond over a transfer length and the damage is more localized. Either way the repair is specialty post-tensioning work with an engineer involved, and the opening usually cannot be used until it is resolved. That single outcome is why scanning is standard practice on any post-tensioned structure.
Can concrete scanning tell a post-tension tendon from rebar?
Not from the reflection alone, because both are steel and both return a strong signal. The identification comes from the pattern: tendons drape through a span so their depth changes along the run, they are usually continuous from edge to edge in banded or distributed layouts, and they terminate at stressing anchors along the slab perimeter, while reinforcing bar sits at a fairly constant cover in a regular grid. A technician reads those cues together with the slab type and any available drawings, and where the answer is genuinely ambiguous the honest response is to treat the target as a tendon and move the penetration rather than guess.
How much does Concrete Scanning cost in Iqaluit, NU?
Private locating is quoted per job rather than off a published rate. What moves the number is how much ground has to be covered, how many utilities are in play, whether the lines are metallic or plastic, how reachable the meters, valves, and tracer wire access points are, and whether you need surface marks only or a drawing and GPS data as well. Ground around Iqaluit runs to permafrost and rocky, which returns the radar pulse rather than swallowing it and hands back reflections of its own, so the difficulty is telling a pipe apart from the ground around it and electromagnetic tracing is what confirms whatever is conductive. Companies price your specific Iqaluit job instead of quoting a flat rate. Submit it once through Utility Hotline and locating companies offering Concrete Scanning around Iqaluit send you their own quotes side by side.
Do I still need to call Nunavut Locates if I book Concrete Scanning in Iqaluit?
Yes, and place that ticket first. Nunavut Locates (1-867-975-5400) is free, is required by law before excavation in most jurisdictions, and brings out the member utilities to mark the public lines they own, generally as far as the meter or the property line. Concrete Scanning does not replace it and is not a substitute for it. What the private work adds is everything one-call leaves out: the lines on your side of the meter, the runs a previous owner installed, and the lines that appear on no map at all. Book both on a Iqaluit site and keep hand or vacuum excavation inside the tolerance zone.
How soon can Concrete Scanning be scheduled in Iqaluit?
Availability belongs to each locating company, and we do not promise a schedule on their behalf. A person reviews your request and sends it to locating companies that cover the area, and each one replies with its own timing and a quote. Saying when you need to break ground in Iqaluit, and whether crews or a paving date are already booked, gets you replies that account for it.
Do locating companies bring Concrete Scanning to the Iqaluit area?
Coverage is settled one request at a time rather than off a published service-area map. Tell us the job site and a person sends your request to the companies that offer Concrete Scanning and work Iqaluit and the surrounding Qikiqtaaluk area, some of which travel further into the Northern Canada for multi-day scopes. What comes back is what tells you who is available for that ground.
