Underground parkade leaks present unique challenges for condo buildings. Water appearing on parkade ceilings or seeping through concrete slabs can originate from plaza deck membrane failures above, plumbing infrastructure, or groundwater intrusion. CondoLeak.ca specializes in determining the source and pathway of parkade moisture intrusion throughout Metro Vancouver.
Common Parkade Leak Sources
Plaza Deck Membrane Failures
Landscaped plaza areas, walkways, and courtyards above underground parkades rely on waterproof membrane systems. Age, UV exposure, root penetration, and installation defects cause these membranes to fail, allowing water to penetrate into parkade spaces below.
Expansion Joint Failures
Expansion joints in concrete parkade slabs are sealed with flexible joint systems that deteriorate over time. Failed joints allow surface water and moisture to penetrate directly into lower levels.
Inadequate Drainage
Parkade floor slopes that don't properly direct water to drains, combined with clogged drainage systems, cause ponding water that finds pathways through concrete cracks and penetrations.
Distinguishing Water Sources
One of our key services is determining whether parkade moisture originates from above (membrane failures, plumbing leaks) or below (groundwater, foundation seepage). This distinction fundamentally changes the repair approach and cost. Our investigation methods include moisture content analysis, timing correlation with weather events, and tracer testing to definitively establish water source direction.
