Structural Assessment and NDT

Advanced diagnostics for structural soundness and durability

Non-Destructive Testing (NDT)

A comprehensive assessment of existing structures is essential for effective maintenance, repair planning and safety assurance. Our advanced Non-Destructive Testing (NDT) services, supported by senior structural engineering expertise, enable accurate evaluation of structural condition, material properties and potential deterioration. Our testing methodologies help identify internal defects, reinforcement conditions, concrete quality, corrosion risks, moisture ingress and other factors that may affect structural integrity, without causing significant damage to the structure.

The findings from these investigations provide a reliable technical basis for condition assessment, repair and rehabilitation planning, structural strengthening and long-term maintenance, helping clients make informed decisions regarding the safety and serviceability of existing structures.

NDT Techniques We Offer:

Ultrasonic Pulse Velocity (UPV) Testing: Assesses internal flaws and material properties of concrete.
Rebound Hammer Test: Evaluates concrete surface hardness and estimates compressive strength.
Rebar Scanning using Profometer and Concrete GPR: Estimates the location, depth and approximate diameter of reinforcement steel.
Concrete Core Sample Extraction and Compression Testing: Determines the grade and compressive strength of the concrete tested.
Carbonation Testing: Determines the extent of concrete carbonation and potential deterioration due to environmental exposure.
Cover Meter Test: Measures the thickness of concrete cover protecting reinforcement bars.
Half-Cell Potential Difference Measurement Test: Estimates the probability of corrosion of reinforcement steel.
Resistivity Test: Measures the electrical resistance of cover concrete to assess the likelihood of reinforcement steel corrosion.
Galva-Pulse Test: Estimates the rate of reinforcement corrosion based on analysis of half-cell potential and concrete resistivity test results.
Thermography and Moisture Measurement: Assesses the extent and intensity of leakages and seepages.
Endoscopic Inspection: Inspects difficult-to-access areas using specialised inspection cameras.
Vibration Meter: Measures structural vibrations for assessment of structural integrity.
Ultrasonic Thickness Testing: Measures the residual thickness of structural steel and helps estimate the percentage of thickness reduction due to corrosion.
Deflection Strain Gauges: Measures deflection during slab load testing.

Applications:

Concrete Strength and Quality Assessment: Estimation of concrete strength and assessment of concrete quality in both new and existing structures.
Condition Monitoring: Evaluation and monitoring of the condition of ageing infrastructure.
Post-Disaster Safety Evaluation: Assessment of structural safety following natural disasters.
Construction and Retrofitting: Integrity checks during construction, repair and retrofitting activities.
