Non Destructive Testing (NDT) Services

At Grimtech, we specialize in Non Destructive Testing (NDT) — a critical process used to evaluate the integrity and reliability of materials and components without causing any damage. Our NDT services help identify hidden flaws, cracks, or defects in materials before they lead to costly failures, ensuring safety, performance, and compliance with industry standards.

What Is Non Destructive Testing?

Non Destructive Testing is a set of advanced inspection methods used to detect internal and surface defects in metals, welds, and structures without altering their usability. This approach is essential in industries like construction, oil & gas, aerospace, and manufacturing, where precision and reliability are crucial.

Our NDT Services Include:

  • Ultrasonic Testing (UT): Detects internal flaws and measures thickness using high-frequency sound waves.

  • Radiographic Testing (RT): Uses X-rays or gamma rays to reveal internal discontinuities.

  • Magnetic Particle Testing (MT): Locates surface and near-surface cracks in ferromagnetic materials.

  • Dye Penetrant Testing (PT): Highlights surface-breaking defects in non-porous materials.

  • Visual Inspection (VT): First-line inspection to detect visible surface flaws.

  • Weld Testing & Flaw Detection: Ensures welded joints meet safety and quality standards.

High Strain Dynamic Pile Load Test:

The High Strain Dynamic load test is similar to the Static load test which evaluates pile load-bearing capacity. The test procedure is standardized according to ASTM D4945 and also forms part of various specifications and code provisions worldwide. The method is convenient, reliable and helps to evaluate pile capacity and integrity in a short time and one or more piles can be tested per day.
The testing is conducted using Pile Driving Analyzer (PDA) Make: PDI, USA, by obtaining and analyzing records of force and velocity under drop-weight impacts. The field results are further analyzed with a signal matching technique (CAse Pile Wave Analysis Program – CAPWAP) to refine the soil parameter assumptions. The output from the test result can be summarized as below:
  1. The static capacity of the pile at the time of testing
  2. Simulated static load test curve
  3. Total skin friction and end bearing of the pile
  4. Skin friction distribution along the length of the pile
  5. Compressive stresses developed in the pile during testing
  6. Displacement of the pile
  7. The integrity of the pile shaft
