Water Filled Barriers
A water-filled barrier ships empty and light, then gets its weight on site from a hose. Once filled, it holds position against people and slow-moving equipment, and it drains for the trip home. That is the main advantage over concrete: no crane to set it and no flatbed full of 4,000 lb sections.
Pick by height and job. Low 20 inch modules mark airport ramps and parking lanes. 32 inch units channel traffic and pedestrians at work sites. 42 inch interlocking units with an optional fence panel on top are what most crews use to close a sidewalk or wall off a work zone.

Buying questions
Are water-filled barriers crash rated?
Most plastic barriers are channelizing and delineation devices, not crash barriers. A small number of systems carry MASH or NCHRP-350 ratings only when installed with their specific connection hardware. Tell us the spec on your plans and we will match it.
How much does a filled barrier weigh?
Roughly 8.3 lb per gallon of water. A 6 ft, 42 inch unit typically holds 150 to 200 gallons, so about 1,200 to 1,700 lb filled versus 100 to 150 lb empty.
Do they freeze in winter?
Plain water will. Crews in cold climates add calcium chloride or a non-toxic antifreeze brine. Ice expansion can split the shell, so drain or treat before a hard freeze.
