WATER-FILLED FLOOD BARRIER
Water-Filled Flood Barrier
A reusable, water-filled tube barrier for flood protection and site dewatering. Fill on site, join end to end, fold flat for storage and transport. Quote per order.
The barrier
What it is
A flexible tube laid empty, then filled with water on site. The water inside holds the barrier in place by weight. When the water is drained, the tube folds flat. It is for homes, warehouses, infrastructure, bridge, culvert and pipeline dry work areas, and municipal and emergency stockpiles.
Laid empty
The tube is laid out empty on cleared flat ground and joined end to end.
Filled with water on site
Fill through a standard fill connection. The water inside holds the barrier in place by weight.
Drains and folds flat
Drain the water, clean and dry the tube, then fold it flat for transport and storage.
Four steps
How it works
Lay the tube out, fill it with water, let the water hold it in place, then drain and fold it away.
Step 22
Fill with water on site
Fill the tube with water on site through the fill connection.

Versus sandbags
Why not sandbags
Sandbags work for small, one-off jobs. For a long continuous line, a water-filled barrier is faster to set out, reusable, and leaves fewer gaps — and it folds flat for transport and storage. Read the full comparison in our guide.
Faster for a long line
A long continuous line is quicker to set out than filling and stacking sandbags.
Reusable
Drain the tube and use it again next time.
Fewer gaps
A continuous tube line leaves fewer gaps than a row of bags.
