Structural & Non-Destructive Testing
Non-Destructive Testing (NDT) utilises a number of methods designed to non-invasively measure the internal properties and condition of engineered structures. NDT methods can be carried out on a wide range of building materials including concrete, masonry, timber and asphalt.
Using NDT methods GBGMAPS can obtain detailed internal condition assessments of a variety of engineered structures. Together with targeted invasive testing, laboratory testing and visual inspection a complete assessment can be made.
- Road pavement
- Rail ballast
- Construction detail of concrete structures including reinforcement spacing, depth of cover and diameters, and concrete thickness and strength
- Assessment of concrete condition including honey combing, delamination, voiding and reinforcement corrosion potential
- Mapping of features within concrete structures including service conduits, poorly grouted PT ducts and void formers
- Assessment of internal condition of timber structures including bridges and power poles
- Construction detail and condition within brick and concrete lined tunnels
- Construction detail and condition of retaining structures including dams and retaining walls
- Assessment of heritage structures
- Pavement layer thickness and condition for roads and runways
- Ballast layer thickness and condition/fouling along rail tracks
- Measuring pile depths
- Thermal imaging for void and leak detection
