The disadvantages of epoxy coated rebar tie wire

There are some products that are seen as huge innovations at first before falling out of use for important reasons a few years later.

In the 1880s manufacturers started using asbestos as an insulator because of its natural fibrous texture, but in the 1970s studies began to indicate its severe impact on respiratory health.

Buildings from before the 1980s often contain asbestos and remain a serious threat to occupants’ health and vitality. My old elementary school was shut down and rebuilt a year after I finished fifth grade and moved onto junior high at a middle school on the other side of the city. Oddly enough, this school remains standing to this day while my high school was rebuilt under similar circumstances as my elementary school. It’s tragic that the World Trade Center was full of asbestos and exposed thousands in the city to toxic plooms when the horrifying events of 9/11 occured in 2001. The real impact of those health effects are unknown, but more is being done all of the time to try to address the problems of those who are still suffering. Sadly we’ve seen other building blunders within the greater construction industry, such as the implementation of epoxy coated rebar tie wire. What could go wrong with rebar completely encased in epoxy? Isn’t this a perfect solution for corrosion? The reality is that the coating is thin and gets tiny micro breaks and knicks in them during installation, leading to slow moisture absorption over time. As the moisture gets in between the metal rebar and the epoxy coating, it corrodes the metal at a rapid rate. If you try to expose the rebar to inspect it, you won’t be able to see the corrosion on the other side of the epoxy. Making the situation far worse than it would be with galvanized rebar tie wire.
