Flood Testing Supervision

Flood testing is the traditional acceptance method for waterproofing membranes on plaza decks, balconies and tank slabs. The test requires careful coordination — water depth, duration, dam construction, drainage, observation — and we supervise these to industry standards on behalf of owners and consultants. The deliverable is a witnessed report with photos, depth-time data and a clear acceptance or deficiency finding.

Why Rain Leak Detection for flood testing supervision

Rain Leak Detection is a sub-division of Leak.ca, the Greater Vancouver leak detection company trusted since 1999. Every site visit is delivered by certified technicians using calibrated equipment, with documented findings formatted for insurance, engineering and procurement use.

We don't sell remediation. Our role is independent detection and assessment — the data you and your professional team work from.

Pairs well with

Clients booking flood testing supervision often combine it with Infrared Roof Survey or Electronic Leak Detection (ELD) — particularly when the underlying issue spans multiple systems or when documentation needs to support a broader investigation.

How to prepare for your visit

1. Document what you're seeing. Photos, dates, sounds, water-bill changes, anything unusual. The more we know in advance, the faster we can locate.
2. Clear access to the suspected area. Move furniture, stored items, and rugs. Non-invasive methods still need clear sightlines.
3. Have system history ready. Recent plumbing work, prior leaks, renovations, age of property, prior insurance claims.
4. Confirm the email for your report. Photo-linked report delivered within 48 hours (often same-day for residential).
