Thermographic Inspections
- Inspections on walls and columns to identify any possible problems during concrete placement so immediate action can be taken to rectify them, saving possible remedial works or complete demolition after formwork is taken off.
- Video recording of concrete placement for quality assurance documentation
- Quality assurance inspections after placement to ascertain if the walls or columns have been adequately filled
Thermography is the use of an infrared imaging and measurement to show and measure thermal energy emitted from an object as a function of their temperature. The infrared energy emitted by an object is known as its heat signature. In general, the hotter an object is, the more radiation it emits.
A thermal camera is capable of detecting small differences in temperature (up to 0.1 of a degree). The thermal camera collects the infrared radiation from objects and creates an electronic image based on information about the temperature differences.
Because objects are rarely precisely the same temperature as other objects around them, a thermal camera can detect the subtle difference in abnormalities in the structure and they will appear in a thermal image such as voiding inside dincel & block walls as well as behind formwork for structural columns and walls
