Dependable precast traffic barrier solutions for directing and protecting pedestrians and drivers.
Why should you incorporate precast traffic barriers in your next project?
Precast traffic barriers serve as medians or guardrails that prevent vehicles from straying too far from the designated area within a roadway. You should consider any potential hazards that a vehicle could encounter and determine whether it would be safer for that vehicle to be stopped by a concrete barrier instead. While it is best to remove the hazard, there are many circumstances where it is not possible to do so. Examples include significant natural features like steep drop offs and lakes, or oncoming traffic on a narrow roadway.
You should also consider incorporating traffic barriers in pedestrian areas, to create organized and therefore efficient patterns of foot traffic.
The advantage of using precast traffic barriers is that implementation is fairly simple. In contrast to poured in place structures, precast installation can be completed with simple machinery and a small group of professionals.

Precast Traffic Barrier Shapes
Jersey (or New Jersey, or K-Rail) Barrier
This barrier is one of the first barriers to be developed and is shaped to minimize the damage done to a vehicle if it comes into contact. It is commonly used to separate lanes of traffic and serves as a median to prevent head-on collisions. Another taller variation, called the Ontario Tall Wall, serves the same purpose but has the added benefit of blocking oncoming headlights. While both types of barrier are modular, they can be linked together for a more permanent application.
The F-Shape Barrier is a variation of the Jersey Barrier. It has the same slope as the Jersey, but a lower slope break point means that it reduces the lift of a vehicle that crashes into it, reducing damage and increasing safety. While it performs better in crash tests, it is not as widely adopted as the popular Jersey barrier.
Constant Slope Barrier
The Constant Slope Barrier has a simpler shape than other types of traffic barriers. It is particularly useful during repaving, because the uniform slope is not affected by the new roadbed height.
These barriers may be offered in shorter segments than other traffic barriers. They incorporate forklift pockets so that they can be put in place in more congested areas where bigger lifts may not be able to maneuver. Typical uses include pedestrian walkways, parking garages, concerts, and vulnerable buildings.
