Security Fencing Considerations

image dsc21186.jpgWhen it comes to security for your perimeter wall there are generally four choices in order of expense. 1.) Do nothing. Normally sufficient, but some areas require additional security. 2.) Shards of glass cemented in place on top of the wall. I’ve never really liked this method. It is ugly, but cheap and at least somewhat effective. 3.) The next step up, which is what I prefer, is barbed wire. This is a method I recently employed on the back plot. 4.) Full fledged security metal. (Note; the decretive security fencing usually applied to the front of the perimeter wall is another topic). Read on to see examples and the methods and costs for utilizing barbed wire.

This application is slightly different in that the height of the wall is only about a meter. The security fencing is then affixed on top of this. This would be a very expensive option indeed, but effective and attractive. Cheaper, but along the same lines, is to affix about 60 centimeter shards atop a full height wall section.

image dsc21083.jpgimage dsc21081.jpgI recently had barbed wire installed on the back 56 meter perimeter wall and a lower adjoining wall section. The workers had just finished the wall and left one of four strands of rebar (used for the post) exposed upward above the wall level. The barbed wire angle metal has opening to accept the barbed wire cut in place.

The height is 45 centimeters above wall section. Note that each post is 2.5 meters apart and there are two strips vertically wired in place to keep the appearance neat and tight.

image dsc21353.jpgI also had barbed wire installed on top of an adjoining wall section. This was a bit trickier as the metal rebar was not exposed to support the barbed wire support shaft. The top surface of the wall was chiseled down about 2 inches, exposing the underlying rebar which is used to support the weld.

image dsc21376.jpgThis is on one side of the house. Since the wall is shorter, the barbed wire goes up to about 90 centimeters on top.

image dsc21368.jpgThe wire is run above the gate section. Originally I had a different design, but this one is sturdier.

The project entailed 56 meters of 45 centimeter high barbed wire and another 15 meters of 90 centimeter high wire. The total cost was about 5600 including 3000 for labor. Barbed wire is purchased in single strand rolls for about 175 per roll. The 1 inch angle iron is 169 per length (each 6 meters long).

I think barbed wire gets a bad rap in some cases, normally because it is applied poorly and looks messy. If applied correctly to a back section, it is inexpensive, study and a good security measure.

  1. as i noted before, a falang cannot have too much security. its tempting to follow what the locals do, but you are not a local

    also locals tend to live in extended families so there are always people about, mostly flangs are the only one of the species around and you never know who is lurking around when you might find yourself isolated. of particular concern are the itinerant labourers and traders up country.

    better be safe than sorry

    having said that thailand is probably one of the safer places in the world to live (who would want to live in the states?). its just that you are perceived as a millionair and potential target. If you were a billionair in europe say, you would have exactly the same problems, so pay up and sleep easy.

  2. Advice to anyone wanting to place barbed wire on their perimeter walls. Have some sturdy stainless steel corner posts made with adjustable wire tentioners. The in between supports can be made of smaller material and only contain holes for the wire to pass thorough. The results are straight tentioned lines of barbed wire.

  3. John: Sounds like a good idea…..do you happen to have a picture of an example of said corner post with tentioners?

  4. dozer. I am back in the UK working for a few weeks. Will dig out some pics and contribute to your blog when back in LOS.
    Only recently found this site, great stuff.
