Crack Monitoring Services by Big Apple Group: Ensuring Structural Integrity


Big Apple Group offers specialized crack monitoring services, using “Telltales” or crack gauges, to ensure the structural integrity of permanent structures on neighboring properties during construction activities. These gauges, typically made of clear plastic and measuring 1-inch tall by 6-inches long, are expertly installed in locations specified by the client and the engineer on record (EOR).


The installation process involves securing the two halves of the gauge on opposite sides of an existing crack, using either epoxy glue or direct fasteners. This design allows the halves to overlap, enabling them to detect and measure relative movements to the nearest 1 mm on a graduated scale. This precise measurement capability makes monitoring crack widths in concrete buildings, bridges, and roads both easy and reliable.
