Concrete Slab Scanning Before Cutting & Sawing in BC
Map embedded elements along every saw line — for plumbing trenches, control joints, demolition cuts, and structural penetrations.
Insurance-Friendly ReportsServing All of BC
Why This Scan Matters
Concrete cutting concentrates risk along a long, narrow line. Where a drill is a point penetration, a saw cut is potentially several feet of continuous opportunity to slice through PT, rebar, conduit, or water lines. The economics are unforgiving: a single 6-foot saw cut through an un-scanned PT slab can mean a multi-week shutdown and a six-figure structural repair.
Our pre-cut scanning service maps the entire cut line plus a buffer zone, marks every embedded element, and produces a marked plan the cutting contractor can work to. For high-consequence cuts (PT slabs, occupied buildings, structural penetrations) we stand by during the first portion of the cut and re-scan if anything reads anomalously.
Most pre-cut scans we run in BC are tied to new plumbing trenches in industrial or commercial slabs, control-joint repair cuts, new partition walls anchored into slab, or full-perimeter cuts for new openings (e.g., new stairwell penetrations).

What We Detect Inside the Concrete
Concrete is rarely “just concrete.” Modern slabs in BC carry a tight grid of structural steel, electrical conduits, water lines, low-voltage cabling, and — in post-tensioned construction — high-tension cables that will fail catastrophically if cut. Our scans map every embedded element before any drilling, coring, or cutting begins.
Reinforcing Steel (Rebar)
#3 through #11 bars mapped by size, depth, and spacing. We mark the actual rebar positions on the surface so your crew can drill between bars, not through them.
Post-Tension Cables
Stressed PT tendons (often 270 ksi) are located and clearly flagged. Cutting one causes a violent recoil that can destroy a slab section and seriously injure workers — never drill blind in a PT slab.
Electrical & Low-Voltage Conduit
EMT, rigid, and PVC conduits up to 4″ trace routing across the slab. We identify branch lines, expansion fittings, and pull-box locations.
Domestic & Hydronic Water Lines
Copper, PEX, and embedded radiant-heating loops located non-destructively. We can also pressure-trace any line you suspect is leaking.
Voids, Honeycomb & Delamination
Hidden voids under the slab, honeycombing inside the pour, and delamination layers detected with GPR + impact-echo cross-check.
Slab Thickness & Cover
Verify slab thickness from one side, measure rebar cover for code compliance, and confirm pour quality before structural sign-off.
Common Scenarios We Solve On This Page
Plumbing trench saw cut
New plumbing trenches in industrial slabs run dozens of feet. We map the entire trench line.
Control-joint repair cut
Damaged or failed control joints get cut and repaired. We scan to ensure no embedded element conflicts.
New door / stairwell opening
New openings in suspended slabs need full-perimeter cuts. We scan all four sides.
Demolition cut for renovation
Major renovations cut slab sections for removal. We scan the cut perimeter.
Topping slab tie-in cut
New topping slabs need tie-in cuts to existing structure. We scan to avoid embedded element damage.
Who Books This Type of Scan
Concrete cutting contractors partner with us as their pre-cut scan provider.
General contractors use our scans for any saw-cut scope.
Structural engineers require scans for cuts in suspended slabs.
Industrial operators use our scans for new trench and pit work.
Our Concrete Scanning Process — Step by Step
1. Pre-scan briefing
Before we step on site we want your drawings, photos, the exact intent (“I need to core eight 4″ holes through this 8″ suspended slab”), and any constraints — live wiring, occupied tenant space, sensitive equipment below. A 5-minute call almost always saves a costly surprise.
2. Site walk & grid layout
On arrival the technician confirms safe access, marks a working grid (typical 1×1 m or 1×1 ft), and photographs baseline conditions. If the slab is dirty or coated we sweep and may light-sand to ensure good antenna contact.
3. GPR scanning passes
We run an orthogonal grid with our 1600/2000 MHz concrete antenna — one set of lines in the X-direction, one in the Y. The real-time image is reviewed on screen; hits are paint-marked on the slab directly as the survey progresses.
4. Verification & cross-check
For high-stakes work (PT slabs, deep cores, occupied buildings below) we cross-verify with a secondary method — electromagnetic locator, half-cell, or impact-echo — to remove false positives and pin down depths.
5. Marking, photos & report
Every embedded element gets a colour-coded mark on the slab (red = PT, blue = rebar, green = conduit, yellow = water/hydronic). Before we leave you receive on-site photos and, on the next 1-2 business days, a stamped PDF report with annotated drawings.
6. Standby for drilling/coring
For complex jobs we stay on site while your contractor drills the first 1-2 holes, so any unexpected reading can be addressed in real time. Once we’re confident, we hand off and you continue safely.
Equipment We Bring on a Concrete Scan
| Instrument | What It Sees | When We Use It |
|---|---|---|
| GSSI StructureScan Mini XT / Proceq GP8000 | Rebar, PT cables, conduits to ~18″ depth; voids; slab thickness | Default tool on every scan |
| 1600 MHz & 2600 MHz antennas | High-resolution imaging of upper 8″ of slab | Shallow drilling, tile/topping work |
| Electromagnetic locator (Hilti PS 1000-style) | Confirms ferrous rebar & conductive conduit | Cross-check on critical hits |
| Cover meter (Proceq Profometer) | Precise rebar diameter & cover depth | Code-compliance reports |
| FLIR T-series thermal | Hydronic loops, hot/cold lines, moisture | Radiant-heat slabs, suspected leaks |
| Impact-echo / ultrasonic (Olson, Pundit) | Voids, delamination, slab thickness from one side | Structural assessments |
| Acoustic correlator & pressure rig | Active water-line leak location through slab | Concrete-encased leak hunts |
Every instrument is calibrated and traceable. Calibration certificates can be supplied with the report on request — useful for tenders, insurance claims, and government work.
What Does a Concrete Slab Scan Cost in BC?
Concrete scanning is priced by the technician’s time and the scope of marking required. As a guide for budgeting:
- Small single-area scan (one room, 1-2 cores) — typically a half-day rate, suitable for residential or single-suite work.
- Medium scope (full floor plate, multiple drill zones) — full-day rate; includes orthogonal grid, marking, and PDF report.
- Multi-floor or PT slab survey — quoted by floor area; PT slabs require additional verification time.
- Stand-by during drilling — hourly add-on; recommended for any post-tension or occupied-suite work below.
- After-hours / weekend work — premium quoted upfront; common for retail and hospital scans where daytime access isn’t possible.
Every quote is itemised and emailed before we mobilise. There are no junk fees, no minimum subscriptions, and no surprise add-ons. Get an honest number at (604) 269-5325.
BC Building Code & Worksite-Safety Context
WorkSafeBC and the BC Building Code don’t mandate a concrete scan by name — but they do mandate that you not cut, drill, or core into a structural slab without first verifying what’s inside. Scanning is the standard of care, and any competent general contractor or strata council will expect to see scan documentation before drilling proceeds.
For post-tensioned slabs the bar is higher still: cutting a PT cable is treated as a near-miss safety incident even when no one is injured. Most municipalities (City of Vancouver, City of Burnaby, City of Surrey, District of West Vancouver, City of Victoria) will ask to see a scan report as part of any tenant-improvement permit involving slab penetrations.
Our reports include the technician’s name, scan date, equipment used, slab area covered, and a marked drawing. That documentation is enough for almost every permit, insurance, and warranty conversation in BC.

Frequently Asked Questions
How long does a typical concrete slab scan take?
A single small area (one room, two or three core locations) typically takes 1-2 hours on site. A full floor plate with multiple drill zones is usually a half- to full-day. We give you a time estimate with the written quote so there are no surprises on invoicing.
Can you scan through tile, vinyl, or floor coverings?
Yes for most thin coverings — ceramic tile, vinyl, sheet flooring, and thin epoxy don’t significantly degrade the signal. Thick carpet pad and certain insulated overlays may require partial removal in the scan zone. We assess access during the pre-scan call.
Will the scan damage my floor, finish, or any equipment?
No. GPR is completely non-destructive — the antenna rolls across the surface like a small cart. There is no radiation hazard, no marks left on the floor (we use water-removable paint or chalk), and no risk to nearby equipment.
What documents will I receive after the scan?
You receive on-site photos of every marking the day of the scan and a stamped PDF report on the next 1-2 business days. The report includes an annotated floor plan, equipment used, slab area covered, technician notes, and depth ranges for every flagged element.
Is the report acceptable for insurance and permits?
Yes. Our reports are accepted as expert evidence by every major Canadian insurer and by every BC municipality we’ve worked with for tenant-improvement and renovation permits involving slab penetrations.
Can you stand by during the drilling or coring?
Yes, and we strongly recommend it for any post-tension slab or any work where the consequence of a hit would be severe. The stand-by rate is hourly and lets us re-scan any anomaly in real time.

A Closer Look at This Service
The cost of finding a leak is small compared to the cost of the damage it causes. A month of undetected leaking can wet insulation, rot framing, wash soil, and attract mould in the time it takes to book an inspection.
The best detection work is done by people who have seen the region’s buildings and buried systems fail in every common way. That experience is what turns a set of readings into a confident, cross-verified answer.
A professional investigation does not end with a verbal summary. It ends with a written report, and that report is the point of the exercise: a document that carries the finding, the evidence, and the guidance to the repair.
How the Investigation Is Delivered
Every investigation follows the same disciplined sequence: consultation, survey, testing, cross-verification, marking, and documentation. The sequence is deliberate, and each step builds on the last.
- Step 1: Consultation to understand the situation and the history
- Step 2: Site survey and indicator mapping
- Step 3: Testing of the suspected systems with matched methods
- Step 4: Cross-verification of the finding
- Step 5: Marking and documentation
- Step 6: Written, dated report
The most common mistake is waiting: waiting for the stain to dry, waiting for the bill to settle, waiting for the leak to announce itself. Water does not wait, and every week of waiting grows the repair scope.
What This Costs
Pricing for this service in British Columbia depends on the scope of the investigation: the systems to be tested, the size of the property, and whether the finding is confirmed with a second method. A fixed quote is provided before any work begins, so there are no surprises on the invoice.
Most property-level investigations in British Columbia are quoted as a fixed fee once the situation is understood. The quote covers the technician’s time, the instruments, the investigation, and the written report.
Insurance and Documentation
Insurance claims fail most often because of missing documentation. A dated, photographed, method-by-method report removes that failure point and gives the adjuster a professional document they can rely on.
For BC policyholders, the practical value is speed: the claim starts with the report already in hand, instead of weeks of back-and-forth while the insurer tries to establish what happened.
What the Report Includes
The written report is the deliverable that separates professional detection from a good guess. It includes the confirmed location, the depth where applicable, the readings, the photographs, the methods used, and an interpretation of the cause and contributing factors.
You keep the report. It documents the finding, the condition at the time of the investigation, and the guidance for the repair, which is useful for warranty, insurance, and future reference.
When to Call
Call before the damage becomes visible if the meter is moving with everything off. That reading is the earliest and cheapest moment to act, and acting early is what makes the repair small.
Call when the indicator is persistent, when it repeats after a repair, or when it is accompanied by a second indicator. A single passing event can be a coincidence; a pattern is a leak.
How to Prepare the Property
The best preparation is information: when the issue started, what changed around that time, what the weather did, and what has already been tried. That history is often more valuable than any instrument.

Common Questions
Is this service non-invasive?
Yes. Every method used works from the surface and leaves no marks. Nothing is cut, dug, or permanently marked during the investigation.
How accurate is the location?
With cross-verified methods, locations are typically within a metre or less, and slab locations within inches.
Is the report useful for insurance?
Yes. The report documents the cause, the extent, the methods used, and the readings, structured for claims and engineering review.
How long does an investigation take?
Most property-level investigations complete within a day, and the written report follows within one to two business days.
Do you repair leaks?
No. Detection and documentation are the service. The report guides the repair contractor to the exact location.
What does this cost?
The quote is fixed before work begins, based on the scope defined in the free consultation. What you are quoted is what you pay.
Call (604) 269-5325 or email info@anyleak.ca for a free consultation. The report is dated, documented, and written to the standard insurers and engineers expect.
