Parkade Flooding: Sandbags for Edmonton Buildings
Parkades flood at the ramp lip, stair cores, and mechanical rooms first. A measured sandbag line at those lips is faster than hoping the trench drain keeps up in a cloudburst.
Map the wet edge
Walk the vehicle entrance at the lowest grade break. Note trench drains, door thresholds into elevators or stairs, and any sloping apron that sheets into the structure. Mark cones or paint temporarily so the night crew knows exactly where the first course goes. Review shared-building roles in condo and townhouse flood prep.
Stage where tires will not hit the reserve
Store pre-filled bags off the travel lane but within a short carry of the lip. Label quantity and the after-hours contact. Keep fire routes and accessible paths open. Bulk planning tips live in property manager staging.
- Protect the ramp toe before secondary bays
- Return bag ends so water cannot travel around into stairwells
- Assign a spotter when traffic is still moving
- Stop outdoor work during lightning
Deploy a lip diversion, not a sealed cavern
Lay poly if the threshold needs it, build one or two staggered courses across the low edge, and guide water toward designed site drainage—not toward the next building door. Do not trap vehicles behind a wall without an alternate exit. After the event, remove bags when safe and restock: $5.99 per bag, min 10, Edmonton Sandbags—call 1-888-552-7263 or quote online; pickup 24/7 at 4315 118 Ave NW.
Board checklist
Log liters pumped if you use pumps, bag counts used, and drain cleaning needed. Pair bags with business continuity planning so the next warning is a procedure, not a scramble.
FAQ
Where do parkade sandbags go first?
At the lowest ramp lip or apron where vehicle water sheets into the structure, with returned ends.
Can bags replace trench drains?
No. Keep drains clear; bags are temporary diversion when volume exceeds drain capacity.
Who should authorize deployment?
Name an after-hours building or property contact in the written flood plan before storm season.
