Driveway and Garage Flooding: Sandbags in Edmonton
Garage flooding usually starts at one low corner of the apron. Protect that corner early with returned sandbag wings—before water spreads across the full door width.
Find the low corner
During a hose test or after light rain, watch where water first crosses the threshold. Most double garages do not flood evenly; one side of the slab or a settled apron concentrates flow. Park vehicles on higher ground before a severe storm if you can do so safely, then close the door before building.
Build from the low edge outward
Lay poly against the door with the lower flap under the first course. Start bags at the low corner, overlap tightly, and extend returns uphill along the driveway edge. Stagger a second course. Do not create a sealed garage with a running engine inside. Keep a pedestrian exit available.
Quantity math for wide doors is in the sizing guide—a five-metre door with returns can need roughly 20 bags for two courses before contingency.
Keep the driveway usable
Do not pile bags in the travel lane where a vehicle must still leave. Stage supply beside the apron on dry pavement. If thunder begins, stop and shelter—see thunderstorm safety.

FAQ
Where should garage sandbags start?
At the lowest corner of the apron, with return ends along the driveway so water cannot bypass the line.
How many bags for a double garage?
Often around 20 for two courses on a wide door with returns; measure your full diversion length and add a few spares.
Should I leave the car in the garage during a flood risk?
If you can safely move it to higher ground before the storm, do so; never run an engine in a closed garage while sealing the door.
