AnyLeak provides non-invasive sub-slab moisture detection for commercial, institutional, and strata floors across British Columbia, mapping below-slab water accumulation, saturated sub-base, and moisture migration without coring or destructive sampling. Moisture beneath a concrete floor slab — from a high water table, failed sub-slab drainage, vapour-barrier breaches, or a buried line leak — causes flooring-adhesive failures, mould in floor assemblies, and slab movement long before it is visible at the surface. Since 1999 we have used GPR slab scanning and infrared thermography to give BC building owners and flooring contractors the sub-slab moisture picture they need before installing or replacing floor finishes.
GPR and Thermal Sub-Slab Moisture Mapping
AnyLeak maps sub-slab moisture using ground-penetrating radar, which images saturated zones and voids in the sub-base as changes in the subsurface reflection, and infrared thermography, which detects the surface thermal signature of moisture migrating through the slab. Together these methods produce a moisture map of the floor area without coring, identifying where below-slab water is concentrated so remediation targets the affected zones rather than the entire floor.
Distinguishing Source: Water Table, Drainage, or Pipe Leak
Effective remediation depends on identifying why moisture is present beneath the slab. AnyLeak distinguishes among a high or seasonal water table, a failed or blocked sub-slab drainage system, a vapour-barrier breach, and a buried pressurised line leak by combining the moisture-distribution pattern with GPR sub-base imaging and, where a pipe leak is suspected, acoustic or tracer-gas confirmation. This source identification directs the owner to drainage, waterproofing, or plumbing remediation as appropriate.
Pre-Flooring Moisture Assessment for Installations
Resilient, wood, and adhered floor finishes fail when installed over a slab with elevated moisture. Before a flooring installation or replacement, AnyLeak assesses sub-slab moisture conditions so the flooring contractor knows whether moisture mitigation is required, preventing the costly adhesive failures and finish delamination that follow installation over an undiagnosed moist slab.
Void and Settlement Risk Identification
Sub-slab moisture often accompanies sub-base erosion and void formation that create slab settlement and failure risk. AnyLeak’s GPR scanning identifies sub-slab voids alongside moisture zones, flagging areas where the slab has lost bearing support so the structural engineer can assess settlement risk and the owner can prioritise sub-base stabilisation before a slab failure occurs.
Signs You May Have a Sub-Slab Moisture Problem
- Flooring adhesive failure, cupping, or finish delamination over a slab
- Persistent dampness, efflorescence, or staining at the slab surface
- Musty odour or mould at the base of walls or under floor coverings
- Floor movement, rocking, or cracking suggesting sub-base voids
- A planned floor installation over a slab of unknown moisture condition

Frequently Asked Questions
Can you detect sub-slab moisture without coring the floor?
Yes. GPR scanning and infrared thermography map sub-slab moisture and voids without any coring or destructive sampling. A confirmatory core is only needed if the owner requires a direct moisture-content reading.
Can you tell whether the moisture is from the water table or a pipe leak?
Yes. We distinguish the source by combining the moisture pattern with GPR sub-base imaging and, where a pipe leak is suspected, acoustic or tracer-gas confirmation.
Should I assess sub-slab moisture before new flooring?
Yes. Assessing moisture before installation tells the flooring contractor whether mitigation is needed and prevents adhesive failures and delamination over a moist slab.
Do you also identify void and settlement risk?
Yes. GPR scanning identifies sub-slab voids alongside moisture, flagging areas of lost bearing support for the structural engineer to assess.
A Closer Look at This Service
Water follows gravity, the path of least resistance, and the buried corridor it sits in, which is why the stain you see is almost never directly above the leak. Understanding where water travels is the entire basis of professional detection work.
A city’s building code, its typical construction era, and its soil behaviour all leave their fingerprints on the leaks it produces. Reading those fingerprints is what makes an investigation accurate on the first visit.
The technician works methodically through the checklist, explaining each step as it happens. Questions are welcome at every stage, and the approach is adjusted when the evidence points in a new direction.
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
A fourth mistake is hiring a repair contractor to find the leak. Contractors are paid to repair, and their interest is in the work, not in the precision of the location. An independent detection team has no repair to sell, only an answer to deliver.
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.
Every property is different, which is why pricing follows the investigation plan rather than a menu. The free consultation defines the scope, and the fixed quote follows it. What you are quoted is what you pay.
Insurance and Documentation
The report produced after a this investigation investigation is written with insurers in mind. It documents the cause, the extent, the methods used, and the readings taken, so the adjuster has everything needed to process the claim.

What the Report Includes
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.
The report is written in plain language first and professional language second. Owners read the conclusion and the cause; contractors and adjusters read the method notes and the readings. Both are in the same document.
When to Call
Call when a repair contractor cannot find the source. Blind replacement of pipe, membrane, or roofing is expensive, and it fails when the true cause is elsewhere. The investigation answers the question the contractor could not.
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
Nothing else needs to be done. The investigation does not require demolition, preparation of the systems, or any work on your part beyond access. Showing up with the history is the whole preparation.
Clear access to the meter, the main shut-off, the water heater, and the areas showing indicators speeds the investigation. A cleared path saves the technician’s time, which is your time on the quote.

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.
