Conventional Crack Monitors

Crack Monitors
Most buildings crack at some time during their service life. Usually the cracks are of little consequence but they may be the first indication of a serious defect. Monitoring the changes in crack width across a crack helps determine the cause of cracking and decide what remedial work should be specified. Avongard offers several options for site monitoring.
Tell-Tales
The Tell-Tales (generic name for crack gauges) manufactured by Avongard Ltd are the original and genuine product.
Avongard Tell-Tales are suitable for use on both on internal and external cracks.
The Tell-Tales are calibrated to 1.00 mm and can be read by interpolation to 0.5mm.
