Flooding remains one of the most costly and devastating natural hazards globally, and Canada is no exception. Recent collaborative research led by Architecture Sans Frontières Québec (ASFQ) and the National Research Council of Canada (NRC) has conducted groundbreaking testing on residential flood defenses, offering valuable insights into how various flood protection methods perform under real-world conditions.
Understanding the Challenge: Residential Flooding in Canada
The comprehensive study evaluated both the vulnerability of typical Canadian home construction and the effectiveness of various temporary flood barriers under simulated flood scenarios, including waves, water pressure, and debris impact. The tests revealed critical leakage points — particularly around door openings and sill plates — where floodwaters most easily penetrate, posing significant risks to home integrity.
Testing Traditional vs. Modern Flood Barriers
Among the temporary barriers studied were traditional solutions like sandbags and plywood coverings, as well as modern, engineered products. FlowStop's inflatable flood barriers were a particular focus, tested for their ability to create a watertight seal on residential openings.
The results were clear:
Proprietary barriers like FlowStop consistently outperformed traditional measures, reducing leakage rates dramatically.
FlowStop barriers maintained their seal under wave action and debris impact, conditions that caused other barriers to fail or become dislodged.
FlowStop’s design — inflatable cushions custom-fitted to openings like doors and windows — ensures a precise, durable seal that adapts even to uneven surfaces, surpassing traditional rigid barriers in effectiveness.
Superior Performance Meets Practical Benefits
Beyond superior performance, FlowStop flood barriers offer unmatched ease of installation. They deploy quickly without heavy labor, unlike sandbag walls which require significant manpower and time to build. The reusable, lightweight design also eliminates the disposal issues associated with traditional flood defense materials.
The rigorous Canadian tests showed FlowStop barriers maintained leakage rates well below the stringent ANSI 2510 leakage thresholds, ensuring minimal water intrusion even in challenging conditions. This aligns FlowStop as a premium option not only in test labs but for real homeowners seeking reliable flood protection.
