CrackChek is our most widely used product line and is based on the conventional Electrochemical Fatigue Sensor (EFS) System, a short-term inspection and dynamic testing. This system determines the activity of an existing crack as well as the presence of microplasticity (the precursor to crack growth) at susceptible locations. The sensitivity of the system is a powerful asset management tool which allows for repair prioritization, QA/QC of retrofit/repair contracts, and reduces mobilizations. EFS™ finds fatigue cracks earlier than conventional NDT methods, including eddy current.

The CrackChek system is specifically designed to also check the efficacy of repairs and retrofits before implementing them on the entire structure or prior to finalizing payment on repair retrofit contracts. The system also allows owners and design engineers to try out several types of retrofit designs and then choose the most cost effective one. Additionally, the system helps to verify “not to repair” decisions. These methods of contract management saves owners valuable maintenance and asset management funds, while helping to ensure the safety of these vulnerable structures.

CrackChek allows owners to determine the activity of existing cracks on their structures (are they still growing?) as well as to determine quantitatively the extent of active cracks at similar details on the bridge. By determining the extent of active cracks on a structure through an iterative QA/QC approach, owners will determine the true status of their structures and reduce inspection and repair mobilizations.
