A Pinhole in the Sub-Slab Vapour Membrane Creates a Point Source of Moisture Drive That Blisters Coatings
A Kewdale cold chain logistics facility had a concrete floor over a sub-slab vapour control membrane — standard construction for cold chain environments to prevent moisture from the ground wicking into the cold store. The membrane had a pinhole failure under one section from a construction penetration that hadn't been sealed correctly.
Surface moisture content testing at the time of our marking showed acceptable levels across the full floor. Moisture tests measure the average moisture content in the upper slab — they don't detect a single-point pinhole moisture source. The primer and marking went down correctly.
Four months later, a discrete patch of osmotic blistering appeared — not spread across the floor but concentrated in a roughly 600mm diameter zone. Classic point-source moisture drive pattern from a pinhole. A plumber's moisture camera located the pinhole at the construction penetration below.
Vapour control membrane integrity can be assessed before marking using an electrical impedance scan of the slab — membrane discontinuities show as localised high-moisture zones in the scan even when surface moisture tests pass. For Kewdale and Perth cold chain facilities where vapour membranes are critical, we now recommend an impedance scan before marking any floor where membrane integrity hasn't been independently verified. MRWA approved.

Frequently Asked Questions
Yes. Kewdale Perth Airport freight terminal and cold chain logistics facilities are part of our Perth inner industrial schedule. Vapour membrane integrity assessment recommended for cold chain floors before marking. We've completed 5,000+ projects nationally since 2009 and carry $20M public liability insurance. Every Kewdale quote includes a site assessment, surface condition report, and fixed pricing. No estimates that change at invoicing. For WorkSafe WA improvement notices we can typically assess within 24 hours and deploy within 48-72 hours. Completion comes with photo documentation, a compliance statement, and material specifications. MRWA approved for any road or carpark marking that requires local council or state road authority sign-off.
Standard moisture tests — capacitance meters, Tramex, or calcium chloride tests — measure average moisture content in the upper concrete slab. A pinhole failure creates a point source of moisture ingress, not a broad elevated moisture zone. The average moisture reading across the slab is normal; only the discrete pinhole location has elevated moisture drive. The failure isn't detectable by standard testing until moisture has migrated far enough laterally to affect the average reading.
An electrical impedance scan applies a low-voltage AC field across the slab and measures the impedance response at regular grid points. Moisture has much lower impedance than dry concrete — membrane failures that allow ground moisture in show as localised low-impedance anomalies on the scan map. A NATA-accredited concrete testing laboratory can conduct the scan. Line Marking Australia has been completing marking across Kewdale and surrounds since 2009, with 5,000+ projects nationally. We carry $20M public liability and $10M professional indemnity insurance, MRWA approved.

We recommend it for any cold chain floor where the vapour membrane is the primary moisture protection and where the construction documentation doesn't confirm independent membrane testing at completion. If the builder has a tested and certified membrane with no penetrations, standard moisture testing before marking is adequate. Surface preparation is assessed before every Kewdale warehouse job, not assumed. That means checking moisture content, surface pH, contamination, and existing coating compatibility before a product is specified. We've completed 5,000+ warehouse and industrial floor marking jobs since 2009, and we carry $20M public liability insurance. Completion documentation includes product data sheets, application records, and compliance certification.
Main Roads WA approved since 2009. Approval means we meet the contractor qualification, insurance, and technical standards required to work on state roads and local government road networks. We carry $20M public liability and $10M professional indemnity coverage, which your risk manager or procurement team can request in writing. All road marking work in Kewdale is done to AS 1742.3 traffic control standards with retroreflective thermoplastic to AS/NZS 1906.3. Traffic management plans are provided before every job. You receive as-built completion photos, a compliance statement, and material certification on completion. We also cover Welshpool, Belmont, Cloverdale on the same schedule.
