    Demark Boundary Fences


    What is a demark boundary fence?


    A fence is said to be a demark boundary because it legally separates two properties. For practical purposes, it defines the property lines of your home and your neighbor’s. Besides defining legal ownership, demarcation fences also provide security by creating a perimeter boundary. The Department of Defense actually requires high security demark boundary fences to be installed at military bases and government facilities both as a warning that a facility is restricted and to delay or prevent incursion.


    What is perimeter security?


    Perimeter security requires a comprehensive plan that prevents unauthorized entry into a property or facility. It not only involves protective fencing but also:


    • Equipment
    • Security Personnel
    • Access control


    What are demark boundary fences made of?


    In retail/consumer terms, a demark boundary fence can be nothing more than a simple wood picket, wrought iron or chain link fence. For high security demark boundary fences, the materials are engineered to be far more robust in order to resist or prevent breaching by manned attack or vehicle ramming. Rolled steel and aluminum are the most common materials used.


    Can a demark boundary fence also be a high security fence?


    Yes. There are many demark boundary fences that are also rated for numerous threats. Protogetic highly recommends that a threat assessment be performed to identify the best type of perimeter fencing for your project, including:


    • Ballistic protection
    • Anti-ram
    • Penetration resistant
    • Anti-climb


    What security options are available for demark boundary fences?


    Demark boundary fences can be outfitted with surveillance and intrusion detection devices as well as physical deterrents.

    • Infrared & thermal cameras
    • Motion detectors
    • Security lighting
    • Alarm systems
    • Warning signs
    • Barbed wire
    • Concertina razor wire
    • Spike toppers


    Is infill and fence fabric the same thing?


    Yes. Fence infill, or “fence fabric as the Department of Defense calls it, refers to the protective material that prevents entry between the fence panel’s frame posts and the top/bottom rails. The most popular infill material is chain link, but this is but one of many infill options available for fencing, depending on your budget. Besides chain link, other infill options include:


    • Expanded metal
    • Wire mesh
    • Palisade
    • Non-conductive
    • Metal screen
    • Welded wire
    • Tubular pickets


    What type of demark boundary or security fence is best?


    No fence is impenetrable given enough time, tools, skill and manpower. There is also no one size fits all solution to perimeter security fencing. The best fence for your project is determined by a through examination of the risks and threats that could be in play. Once again, hiring a qualified security expert or engineer to perform a threat assessment is our first recommendation.


    What if my demark boundary fence needs to be DoD-approved?
