If you have the need for immediate security, consider using jersey barriers.  A jersey barrier is perfect for blocking off areas, controlling vehicle traffic, and crowd control.  Police have even used jersey barriers in response to bomb threats.  Short term jobs or smaller projects do not justify the use and cost of concrete barriers.  You can get the same level of security and crowd control with plastic jersey barriers.  The barriers are not permanent and are more cost effective.  You can use plastic jersey barriers over and over again, which also helps to reduce cost.

Plastic jersey barriers come in bright colors and are highly visible and are easily seen by motorists.  Plastic barriers are easy to move.  You do not need a crane or any special equipment every time you need to move them.  When filled with water or sand, the barriers are very stable and will not move or shift.  Although the barriers are made out of plastic, the walls are thick and internal support gives them a long life span.  You can use the barriers in freezing weather without damage.  Each barrier has large fill holes.  This makes it easy to fill the barriers with sand or water.  It also makes it easier when it is time to drain and store the units.
