Crack monitoring is an essential item to determine stability of any critical structure, and a way to document if the structure has been impacted at all since the formation of the crack.

“Telltales” also known a crack monitoring gauge are installed and monitored on any open joints in the permanent structures on neighboring properties in locations specified by client and the engineer on record (EOR). The gauges are clear plastic that measure 1-inch tall by 6-inches long and come in two halves. The two halves are secured using epoxy glue or a direct fastener on opposite sides of an existing crack. The halves overlap such that they can detect relative movements that are measured to the nearest 1 mm on a graduated scale. Monitoring crack widths in concrete buildings, bridges, and roads is easy and reliable with Concrete Crack Monitors. Opening and closing and differential movement of the crack is continuously monitored.
