A Water Filled Barrier (WFB) is an alternative to concrete barrier wall that also provides positive protection to safely separate work crews, pedestrians and motorists in urban areas or low speed work zones. It is light weight, highly visible, easy to transport and can be set in place without any equipment.
Water filled barriers can also be used for channelizing vehicles and pedestrians for special events. Each piece can be set individually or by locking them together with a metal pin. They can be used with or without water.
