FionaZuppa...Thanks for the link to the thread. That is impressive damage for sure.
Many thanks Bob for the link you provided. I remember reading this article about Mr Ufer some years ago as a result of this forum, but I've since forgotten much of the important information. You're right...there will always be odd events, especially with lightning. Thanks again.Buck, I am not an expert here but I look at it this way.
If the lightning strike was/is so direct that it blows apart the ufer there is nothing you can do. Take away that ufer and something else is going to be damaged.
There will always be odd events, consider seat belts, more often than not they save peoples lives but sometimes they are the cause of death. You just got to go with the odds and hope for the best.
Here is some uffer info and if it was good enough to protect military ammo dumps I am good with it for a normal building. http://www.psihq.com/iread/ufergrnd.htm
