Constructed from LDPE and weighing 57 lbs when empty, it becomes fully effective once self-filled with floodwater. The 39.4-inch long barriers interconnect via multi-hub keys (supplied with each unit), which allow for angle changes and wall connections—ideal for enclosing areas or rerouting water around sensitive infrastructure.
- Self-balancing – No mechanical fixings required; the filled base provides reliable, wind-resistant ballast.
- Reusable and recyclable – Built for long-term use in high-risk flood zones or repeat deployment sites.
- Visual warning colors – Red and white as standard; other colors available for large orders.
- No digging or surface prep – Works on tarmac, concrete, and level soil. Not recommended for gravel.
- Faster than sandbags – Clean to store, transport, and deploy during emergencies or seasonal flooding.
The Floodstop 35.4in system is relied on by municipalities, facility managers and large contractors working in coastal towns, flood plains, and high-risk basements or utility networks. Its elevated height makes it the go-to option when typical 19.7in barriers fall short—protecting key entrances, data centers, substations and plant equipment from deeper floods.
With no permanent fixtures or expensive install costs, this barrier delivers long-term security with complete flexibility. Whether you’re responding to a weather warning or planning for a flood-prone winter season, this water filled barrier allows proactive protection with minimal overhead.

What makes this different from the 19.7in Floodstop?
This unit is 35.4in high and heavier when filled, offering greater protection for high-water-risk sites or deeper flood zones.
Is it easy to install alone?
Yes. One person can deploy each 57 lb unit without tools or lifting gear.
Do I need to add ballast?
No. The self-fill system uses water ingress to automatically provide ballast during use.
How do I store them?
Floodstop barriers are designed to nest inside each other when empty, minimizing storage footprint.
What ground surfaces is this suitable for?
Best for hard surfaces, flat soil or grass. Not recommended on loose gravel or highly uneven terrain.
