While doing structural assessment, it’s essential to identify the cracks and differentiate the cracks as structural and non-structural cracks. If the cracks are structural cracks, then it becomes very important to measure the crack width and check whether the cracks are dead or are live.
To measure the crack width and movement, various Crack scopes and Crack movement devices are available. The crack scopes can magnify the crack about 25 to 100 times and can measure up to a level of 0.0025 mm.
