Podium Deck Leak Investigation in Delta, BC

Podium decks — concrete structures buried beneath landscaping, paving, or green roof assemblies — are among the most challenging leak scenarios in BC's building stock. The waterproof membrane is buried beneath soil, drainage layers, insulation, and hardscaping, making the exact leak entry point invisible from the surface. Water that penetrates the membrane migrates laterally along the structural slab, appearing far from the actual breach. Our podium deck investigation uses a systematic process of acoustic listening, thermal imaging, tracer gas injection, and flood testing to isolate and locate the membrane breach. We work with building envelope consultants and restoration contractors to provide the precise location data needed for targeted membrane repairs, avoiding the cost of wholesale deck replacement.
