Crack Growth Measurement

Gaps and cracks in any structures happen all the time. These types of damages occur as commonly in brick structures as in concrete (reinforced concrete, pre-tensioned and post-tensioned concrete elements). Monitoring the cracks to see whether they are live or dead is of vital important on how to repair them and how serious they will get in the future.

One of the most commonly used methods to measure, if a given fissure or crack “shifts” with time, is the so-called “glass method”. The brittleness of glass makes even the slightest change in fissure width (less than 0.1 mm) result in the breaking up of the “measurement instrument”.

One of the tools we can offer to monitor the width of cracks in structures, is our Crackmeter, installed on the cracked area.
