AnyLeak performs waterproofing membrane integrity testing for roofs, plaza decks, planters, and below-grade structures across British Columbia, verifying and locating breaches in newly installed and existing membranes using recognised methods — vacuum-box testing, spark (holiday) testing, and controlled flood testing. Membrane integrity testing confirms whether a waterproofing system is continuous before it is covered by overburden, pavers, or backfill — the point after which a breach becomes enormously expensive to find and repair. Since 1999 we have helped BC owners, consultants, and waterproofing contractors verify membrane performance at the one moment when defects can still be corrected economically.
Vacuum-Box Testing of Seams and Details
Vacuum-box testing applies a transparent chamber and negative pressure over a membrane seam, detail, or penetration flooded with a soap solution; bubbles reveal any breach pulling air through the membrane. AnyLeak performs vacuum-box testing of critical seams, drains, and penetration details on roofing and below-grade membranes, confirming the integrity of the highest-risk locations before they are covered and documenting each tested location for the consultant and contractor records.
Spark (Holiday) Testing of Liquid-Applied Membranes
Spark testing, also called holiday testing, passes a high-voltage probe over a conductive-primed liquid-applied or sheet membrane; a breach completes a circuit to the substrate and triggers an alarm at the exact defect location. AnyLeak performs spark testing of liquid-applied waterproofing on decks, planters, and below-grade walls to find pinholes and thin spots invisible to the eye, marking each defect for repair before overburden is placed.
Controlled Flood Testing of Horizontal Assemblies
Flood testing temporarily dams and floods a horizontal waterproofing assembly to a specified depth for a set duration, confirming the membrane holds water before it is covered. AnyLeak conducts controlled flood testing of roof and deck assemblies in coordination with the structural engineer’s confirmation of load capacity, observing the underside for any penetration and documenting the result as evidence of a watertight installation.
Locating Breaches in Covered and Existing Membranes
When an existing membrane already covered by overburden leaks, AnyLeak combines integrity-testing principles with infrared thermography and electronic leak detection to narrow the breach location, minimising the overburden that must be removed. This targeted approach turns an otherwise blind “remove everything and re-waterproof” situation into a localised repair of the specific failed area.
Membrane Integrity Test Methods
| Method | Best For | Result |
|---|---|---|
| Vacuum box | Seams, drains, penetration details | Bubble indication at a breach |
| Spark / holiday | Liquid-applied and sheet membranes | Alarm at the exact defect |
| Flood testing | Horizontal roof and deck assemblies | Confirms the assembly holds water |
| Infrared + ELD | Existing covered membranes | Narrows breach to localise repair |

Frequently Asked Questions
When should membrane integrity testing be done?
Before the membrane is covered by overburden, pavers, or backfill — that is the one moment a breach can be found and corrected economically. Testing also helps locate breaches in existing covered membranes.
What is spark or holiday testing?
A high-voltage probe is passed over a conductive-primed membrane; a breach completes a circuit to the substrate and triggers an alarm at the exact defect, revealing pinholes and thin spots invisible to the eye.
Can you flood test a roof or deck safely?
Yes, in coordination with the structural engineer’s confirmation of load capacity. We dam and flood the assembly to the specified depth and duration and observe the underside for penetration.
Can you find a breach in a membrane already covered by pavers or soil?
Yes. We combine integrity-testing principles with infrared thermography and electronic leak detection to narrow the breach location and minimise the overburden that must be removed.
A Closer Look at This Service
The most expensive leak is the one that was never located. Exploratory openings, repeated drywall repairs, and months of a running meter all cost more than a single professional investigation with an exact answer.
Every city in British Columbia presents its own combination of soil, climate, construction stock, and water systems, and detection work has to respect those differences. The plan is built accordingly.
The investigation is a quiet, methodical process. Instruments are calibrated on site, readings are recorded, and the technician explains what each step is looking for. There is no demolition, no noise beyond the instruments, and no mess left behind.
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
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
The report also protects the policyholder. When the cause is documented at the time of the loss, there is no later dispute about what was found, when it was found, or what the condition was.
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.
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.

When to Call
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.
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.
How to Prepare the Property
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.
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.

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.
