Extreme rainfall: how to keep water out of your garage

During heavy rainfall, downhill garages — those with entrances below street level — are particularly vulnerable to flooding. Water naturally follows the downward slope, putting not only the building but also all stored belongings at serious risk. For homeowners, this represents a major concern, both in repair costs and stress.

This is where FlowStop flood barriers make all the difference.

Why are downhill garages so at risk?

Unlike standard garages, a downhill garage acts much like a funnel: it collects rainwater flowing from the street or driveway. Even with functional drains, during extreme rain events — increasingly common due to climate change — drainage systems can quickly become overwhelmed.

The result: water accumulates like a swimming pool and can seep in within minutes.

• Easy to Use: Lightweight and manageable, the system can be installed by a single person.
  

Case study: a garage saved thanks to FlowStop

During last summer’s torrential rains, a resident of Laval avoided thousands of dollars in damage thanks to his FlowStop barrier. Despite more than 50 mm of rainfall in less than an hour, the barrier held firm, preventing water from flooding his garage and basement.

“Without this barrier, I would have had over a meter of water in my garage. It’s an investment I would make again without hesitation.” — Martin L., FlowStop client
