Tiger Dam + StormBag: Where Each Wins, and Why Most Facilities Need Both
If your hotel, hospital, data center, or industrial site already runs Tiger Dam for perimeter flood protection, you've made the right call for the building footprint. Tiger Dams are FM Approvals Platinum Level certified, stackable from 18 inches to 32 feet, and the only patented water-filled barrier system that connects end-to-end for miles in any shape. For a perimeter ring around a high-value property, nothing else matches them.
But every facility manager who has actually deployed a Tiger Dam during a real event knows the same thing: a perimeter is not a building. Water gets in through doorways, loading docks, elevator pits, stairwells, and the dozens of interior choke points where a 50-foot tube physically cannot reach. That's where StormBag earns its place in your kit — not as a replacement, but as the tool for everything Tiger Dams can't.
What Tiger Dam does well — and what it asks of you
Tiger Dam is purpose-built for one job: holding back a wall of water around the outside of a structure. Done right, the manufacturer claims the system can divert up to 100% of floodwaters. It scales to refinery, utility substation, and shoreline-length deployments. U.S. Flood Control's published applications list includes hospitals, prisons, police departments, EOCs, hotels, and golf courses — exactly the customer profile that already knows the value of perimeter defense.
The trade-off is the deployment requirements:
- Manpower. 50-foot tubes don't lay themselves out. A perimeter deployment is a multi-person operation under time pressure.
- A water source at volume. Tiger Dam's preferred fill is a fire hydrant. A 2-inch pump or garden hose works, but pump means longer fills and a hydrant means access negotiations with the local fire department.
- Hours, not minutes. Real-world perimeter deployments around a commercial property are measured in hours of crew time before the first wave hits.
- Exterior geometry. Tiger Dams curve, but they don't curve tight. A recessed entryway, a sub-grade loading dock, or a doorway flanked by planters is a problem for a 50-foot tube.
None of that is a flaw — it's the cost of the protection level Tiger Dam provides. It's just a list of things that have to be true before a Tiger Dam goes down.
Where StormBag fits in your existing kit
StormBag is a FEMA and DHS approved sandless sandbag. One pound dry, 33 pounds hydrated in three minutes, six-inch barrier height per layer. One person, no pump, no hydrant, no anchoring. Hydrate with a garden hose or a five-gallon bucket, drop it in place, walk away.
That changes what's possible in three specific places where Tiger Dam isn't the right tool:
1. Doorways and back-of-house openings
Every hospitality property, hospital, and office building has the same map: front entry, side entries, employee entrance, loading dock, kitchen receiving door, mechanical room thresholds, elevator pits, stairwell entries, ground-level housekeeping or engineering doors. Each one is a leak path even when the perimeter holds. A four-foot doorway needs five StormBags. A loading dock might need fifteen. Pre-staged door kits turn each opening into a five-minute job for whoever happens to be closest.
2. Surge events that move faster than crew deployment
A flash flood warning, a burst water main upstream, a hurricane that intensified overnight — these are scenarios where the interval between "we need to deploy" and "water's at the door" is shorter than a Tiger Dam crew callout. Pre-staged StormBag cases in housekeeping closets, engineering, and back-of-house corridors give your on-shift staff a tool they can deploy now, while the perimeter crew is still en route.
3. Geometry the tubes can't reach
Tight corners. Recessed doorways. Ground-level windows on a tiered building. Curved façades. The dozen spots where a 50-foot tube physically can't conform without leaving a gap. StormBags conform to any shape because each bag is a one-by-two-foot building block. You stack and shape them around the obstacle.
Three deployment patterns from facilities running both
Layered defense. Tiger Dams on the exterior perimeter for the building footprint. StormBag on every guest-facing entry, every back-of-house opening, and every mechanical/utility door inside the perimeter ring. If perimeter water rises above the dam height or a section seeps, the doors are still sealed.
Time-staggered deployment. StormBag pre-staged for the first 30 to 90 minutes of a fast-moving event. On-shift staff deploys door-level barriers immediately. Tiger Dam perimeter crew deploys behind them on a longer timeline. Your protection scales up as your response scales up, instead of being all-or-nothing.
Last-mile gap-filling. Tiger Dam runs the long perimeter. StormBag fills the corners, recessed entries, ground-level windows, and tight geometry where a tube can't curve in. Same protection envelope, no gaps.
The unglamorous use case: water that's already on the floor
Storm season is the headline. The other 11 months are burst pipes, HVAC condensate overflow, dishwasher leaks, ice machine failures, sprinkler trips, and the slow drip that nobody notices until the carpet pad is soaked. Each StormBag absorbs roughly four gallons. The same case you stage for hurricane prep handles every routine water event in between.
This matters for the math on stocking StormBag at a commercial property. It's not a box you buy and hope you never use. Engineering uses them on water heater leaks. Housekeeping uses them on overflow toilets. Facilities uses them after sprinkler activations. The case turns over.
Specs, side by side
| Tiger Dam | StormBag | |
|---|---|---|
| Best for | Building perimeter, shoreline, large diversion | Doorways, choke points, interior leaks, gap-filling |
| Deployment crew | Multi-person team | One person per door |
| Fill source | Fire hydrant (fastest), 2" pump, or garden hose | Garden hose, bucket, or any standing water |
| Time to barrier | Hours for full perimeter | 3 minutes per bag, hydrated |
| Barrier height | 18 in to 32 ft (stacked) | 6 in per layer (stackable) |
| Storage | Folded tubes + accessories, larger footprint | 1 lb each, stores flat in cases |
| Approvals | FM Approvals Platinum Level | FEMA + DHS approved, National Guard field-tested |
| Off-season utility | Sits in storage | Doubles as spill/leak absorbent |
The right answer for most commercial properties isn't one or the other. It's Tiger Dam for the perimeter, StormBag for everything inside the perimeter and everything the perimeter can't reach.
How to stage StormBag at a multi-building property
If you're already running Tiger Dam, your facility team understands flood deployment logistics. Adding StormBag is a smaller version of the same exercise.
- Walk the property and count entry points. Front, side, employee, loading dock, kitchen receiving, mechanical rooms, electrical rooms, elevator pits, stairwell entries, ground-level windows in the flood path.
- Size each opening. Five StormBags per four-foot doorway, ten for an eight-foot opening, fifteen for a single-wide garage or loading dock, twenty-five for a double-wide. Our sandbag count guide walks the math.
- Pre-package by zone. Housekeeping floors, engineering shop, back-of-house corridors, parking-level mechanical rooms. Label cases by zone so on-shift staff grab the right one without thinking.
- Add a fill plan. Identify the nearest hose bib or utility sink to each staged case. Mark it on the deployment map. A bag that can't be hydrated in three minutes isn't a three-minute bag.
- Train on a quiet day. Five minutes of practice per shift is the difference between StormBag working and StormBag sitting in a closet during the event.
Important note for coastal properties: StormBag cannot be hydrated in salt water, but will work to repel salt water once they are hydrated with fresh water. Stage your fill source on the fresh-water side of the building.
