Why do I need to monitor a crack?

Most buildings crack at some time during their service life. Usually, the cracks are of little consequence, but they can also be the first indication of a serious defect. Monitoring the changes in crack width across the crack helps determine the cause of cracking and decide what remedial work should be specified.

The Avongard Tell-Tale is the original crack monitoring system. We supply a range of products for monitoring the movement of cracks and these can be used on external and internal cracks on walls, floors and ceilings.

Avongard is a UK company, established in the 1970s and with over 40 years of experience of monitoring cracks. We are the market-leader in crack monitoring products, and we supply gauges for the monitoring of cracks in buildings and civil engineering structures worldwide.
