Non-Destructive Diagnostics & Testing
Proper repair concrete methodology should begin with testing, to identify the type and extent of defects and the overall quality of the concrete or steel structure.
Gemite offers Non-Destructive testing to deliver an analysis of the existing conditions, and help to determine the most appropriate repair method and materials to use.
Non-Destructive techniques and equipment used by Gemite provide instant and precise information regarding the concrete electrical resistance, probability and rate of rebar corrosion, location of hidden flaws, placement of reinforcement, reinforcement cover, concrete compressive strength and structural rigidity. The diagnosis also includes determination of chloride-ion content, its distribution and carbonation depth.
As part of the service, Gemite also provides co-ordination and analysis of laboratory testing such as compressive strength, petrography examination, and alkali aggregate reactivity (AAR).
NDD Methods (partial)
Ground penetration radar scanning & 3D imaging
Radar uses electromagnetic pulses to penetrate concrete up to 1 m (3’) and produces high-resolution images from the reflected waves of embedded volumes, which exhibit different dielectric characteristics.
The method is used mainly in determining internal defects, voids, positioning of reinforcing steel and other objects embedded in the concrete.
