Existing structural cracks are often discovered during the pre-construction survey process. It is in all parties' interest to document the before and after state of cracks for insurance claim purposes. Municon works as a trusted 3rd party to employ a variety of different crack gauges and crackmeters to create baseline readings before construction initiates. As a crack begins to grow, our equipment provides a reliable measurement as to how much it has changed since the last reading. Alternatively, our gauges will also provide evidence if the cracks have not changed since pre-construction.
