I remember seeing an article in one of the trade mags about crack
monitoring.  In the article the author used 2 buisness cards fixed to each
side of a crack in a concrete wall.  I don't remember how he attached the
cards.

Has anyone ever used a home made crack monitor using 2 buisness cards?  How
did you affix the cards to the wall?

Dear Members:

 

At collapsed buildings, in major disasters (many hundreds if not thousands of collapsed buildings) time and simplicity are of the essence. Having said this and considering that our very lives are at risk as we crawl inside these piles of rubble it is necessary to be practical and highly functional ( I have personally crawled inside of 894 collapsed buildings).

 

We wet a piece of paper (usually 8"X10") and stick it over the crack. The wet paper will stick by itself.

 

If there is any movement whatsoever the wet paper tears.

 

Simple yet effective.
