Crack measurement involves recording cracks at the concrete surface to provide a descriptive record which can be complemented with photographs. The important features to record are: pattern of cracking, spacing, length, number of cracks, orientation with respect to reinforcement, concrete surface condition and crack width. The pattern of the cracks helps to identify the likely cause[1, 2]. This document aims to offer advice on measuring the maximum surface crack width.
