Most flood barriers are built for construction sites. FlowStop was designed for homeowners.
| ❌ Metal Barriers | ✅ FlowStop | |
|---|---|---|
| Seals on uneven floors | Needs a perfectly flat surface. Gaps are common on older driveways and door thresholds. | Inflates and molds to any surface — cracks, slopes, uneven edges. No gaps. |
| Impact from debris | One hard impact can dent the frame and break the seal for good. | Bounces back from impacts without losing its seal. Keeps protecting. |
| Setup time | 30–60 minutes. Usually needs two people and a drill. | One person. Under 5 minutes. No tools, no drilling, no help needed. |
| If something goes wrong | A bent frame means the whole unit is done. Can't fix it on the spot. | A simple patch fixes a puncture. Back in service the same day. |
| Off-season storage | Bulky panels and metal frames. Takes up serious garage space. | Deflates into a compact bag. Stores in a closet until next season. |
| Materials | Mechanical bolts and gaskets — multiple points that can fail. | Same materials as inflatable rescue boats. Built for when failure isn't an option. |
| vs. Sandbags | — | One FlowStop replaces 50 sandbags. No heavy lifting, no mess, no wasted bags. |
