- Gate entrances and parking areas
- Mess halls, barracks, and munitions areas
- Utility plants and manufacturing facilities
- Office and commercial buildings
- City streets and piers
Concrete security barriers are the preferred choice for security applications for a number of reasons:
- Concrete is virtually maintenance free when compared to other materials.
- Steel reinforced concrete barriers have a minimum of 4,000 psi strength at time of shipment.
- The average density of concrete barriers is about 3,500 to 3,700 pounds per cubic yard, which allows for unanchored portable barriers.
- Concrete barriers can be quickly repositioned to meet changing needs.
- Due to availability, maintenance, effectiveness, and speed of installation, concrete barriers are extremely cost effective.
