SAND & WATER FILLED BARRIERS
A proper traffic barrier is extremely important to delineate lanes and separate construction areas on highways, but in today’s world they also serve a security purpose in protecting pedestrians from vehicles in large crowd situations. There are many different styles and options, so which one is right for your application? Let's take a look.
But first, a bit about water and sand filled barriers. Typically, they are large hollow barriers made of UV-resistant polyethylene, which helps them last long in outdoor use applications. They are often available in many color options, but the most common is safety orange, due to its high visibility.
There are usually one or more lids or caps near the top of each barrier to aid in the filling process, and a drain plug near the bottom to help empty the barriers when they’re no longer being used. They feature modular construction that allows barriers of a similar style to interlock together to form a continuous, unbroken line. Other types are even stackable, creating a taller barrier.
The term Jersey wall or Jersey barrier refers to a lane separating barricade that is meant to minimize vehicle damage and prevent lane crossover that could result in a head-on collision. Originally concrete, many Jersey barriers are now of the plastic fillable variety. This prevents the barriers themselves from becoming a collision hazard.
Jersey barriers interlock to create an unbroken and clear delineation, especially when safety orange coloration is used. This makes them more effective than channelizer drums or cones, as it prevents drivers from weaving through spaces and ending up in a dangerous situation. Certain styles even offer corner pieces that allow you to create 90 degree turns in your barrier line.
Jersey wall style barriers are usually trapezoid shaped in the cross section, with a wider bottom that tapers to a thinner top, allowing it to have a better center of gravity to prevent toppling. They also frequently have built in slots for forklifts which makes them convenient to transport.
As the name implies, stackable barriers can be built up vertically in addition to interlocking horizontally. This allows a barrier to be built higher than a simple Jersey wall. The height also serves to discourage people from climbing over the barrier to access off-limits areas.
Some styles fit together like Lego blocks, with circular pegs on top that fit into slots on the bottom of other pieces. These types have caps that fit on the uppermost piece to create a flat top, and optional doors to allow you to pass through the barrier at certain points.
