Parkade Ceiling & Planter Box Leak Detection — BC Specialists
Find waterproofing failures in parkade ceilings, podium slabs and rooftop planter boxes
About This Service
Parkade ceilings (the underside of the occupied podium or ground-level slab) and rooftop planter boxes are major leak sources in BC strata buildings. Water migrates through failed membrane, cracked concrete or blocked drainage and appears as staining or active dripping on the parkade ceiling or through the building envelope. We use thermal imaging and moisture mapping to identify the failure zone above without requiring immediate demolition of landscaping or paving.
Common Causes
Warning Signs
- Water staining, efflorescence or active drips on the parkade ceiling
- Rust staining from rebar corrosion indicating long-term moisture penetration
- Cracked or spalled concrete on the parkade ceiling soffit
- Water ponding or wet soil in planter boxes that doesn't drain
- Staining on exterior cladding below rooftop planters
- Heaving or cracked paving above the parkade deck
Detection Process
- 1
Visual inspection of the parkade ceiling to map staining, efflorescence and active drip locations.
- 2
Thermal imaging of the ceiling from the parkade to identify wet insulation and moisture zones.
- 3
Correlation of ceiling stain patterns with the slab layout above (planters, drains, joints, penetrations).
- 4
Targeted probe testing at cracks and joints to confirm moisture at depth.
- 5
We map the moisture extent and locate the primary failure zones for the membrane contractor.
What You Receive
- Thermal imagery of parkade ceiling showing moisture extent
- Failure zone map correlated to the slab plan above
- Probe moisture readings at suspect locations
- Written report for strata council, engineer and waterproofing contractor
- Priority ranking of repair zones by severity
Strata Responsibility Note
Podium slab waterproofing and parkade structure are common property in BC strata buildings. Repair costs are typically funded from the contingency reserve. A thermal inspection report is required by most engineers before specifying repair scope, and by most insurers before approving a claim.

Frequently asked questions
Do we need to remove the landscaping or paving to find the leak?
Not initially. Thermal imaging from the parkade below identifies the moisture zones above without disturbing surface finishes. This allows the engineer and contractor to target their investigation and minimise the area of landscaping or paving that must be removed.
The parkade ceiling stain has been there for years. Is it still worth investigating?
Yes — ongoing moisture causes progressive rebar corrosion and concrete deterioration. Understanding whether the leak is active or historic, and exactly where it's entering, is essential for planning a cost-effective repair before structural damage becomes severe.
Can you scan the slab directly above the parkade as well?
If the area above is accessible (landscaping, paving, or interior slab), we can add GPR scanning to map the membrane condition, locate drainage components and assess structural integrity. This is recommended when a full repair scope is being planned.
