Our Non-Destructive Testing Services in Civil Engineering
We provide a complete range of Non-Destructive Testing Services in Civil Engineering that designed to ensure safety, reliability, and performance of civil structures. Our expertise covers:
The Bridge Load Test is performed to assess whether a bridge can safely carry the required loads. In this method, controlled loads such as trucks or heavy vehicles are placed on the bridge, and sensitive instruments measure the deflection and stress on the structure. This test gives real world insights into how the bridge behaves under traffic
conditions. It helps engineers determine the bridge’s load bearing capacity and ensures compliance with safety standards.
Also known as the Schmidt Hammer Test, this method is one of the simplest and fastest ways to check surface strength of concrete. A spring loaded hammer strikes the concrete surface, and the rebound value indicates the hardness of the material. The higher the rebound, the stronger the surface concrete. This test is widely used for quick inspections, quality checks, and comparison between different concrete areas on site.
The UPV Test measures the quality and uniformity of concrete using ultrasonic sound waves. A pulse is passed through the concrete, and its travel time indicates the density and condition of the material. Fast travel times mean the concrete is dense and strong, while slow times may signal cracks, voids, or internal weaknesses. This test is highly effective in identifying hidden defects that cannot be seen on the surface.
The Falling Weight Deflectometer is a modern tool used to evaluate pavement and road conditions. In this test, a weight is dropped on the road surface to simulate the load of a passing vehicle. Sensors then measure the deflection of the pavement. This information helps engineers understand the structural strength of the road layers and
decide whether maintenance, strengthening, or reconstruction is required.
Network survey Vehicle (NSV)
The NSV is a specially equipped vehicle designed to survey roads and highways efficiently. It uses high-resolution cameras, sensors, and lasers to record details such as surface cracks, rutting, roughness, and overall ride quality. The data collected helps create accurate road condition reports, which are essential for large scale maintenance planning and budget allocation. Unlike manual inspections, the NSV method is fast, safe, and covers long stretches of road in minimal time.
Roughness Test by Fifth Wheel Bump Integrator
Road roughness directly affects driving comfort, safety, and vehicle maintenance. The Fifth Wheel Bump Integrator measures road roughness by recording bumps and vibrations as a vehicle moves over the surface. This test provides valuable data for calculating the International Roughness Index, which is a global standard for evaluating road smoothness. Authorities often use this test to monitor road quality and schedule timely repairs.
