Crack Monitor Gauge

danjo

Anybody know where I can get a crack monitoring gauge in or around Dublin?
These are the little devices that are screwed to a wall and show movement in cracks over a period. Appreciate any help. :eek:

I think some of the bigger builder supply depos will do them.

What I have used in the past is super glue and the thin pieces of glass used in microscopes in a lab. They snap if there is movement. you just take pictures

Hi..
Depends on the accuracy required... We used two plastic rulers, overlapped one above the other. One firmly fixed to each side of the crack, this gives a vernier type scale as one moves past the other.
If you need more accurate measurment then a purpose build device is required..
Cheers.
