Building Condition Survey, Structural Analysis and Audit, Pile Integrity Testing, Rehabilitation of Vulnerable Structures

Non-destructive testing (NDT) is used to examine the condition or the quality of a structural element without damaging it. We offer the following services using non-destructive techniques:

  • Reinforced Cement Concrete (RCC)
  • Rebound Hammer tests for assessing the concrete compressive strength.
  • Ultrasonic pulse velocity tests for establishing quality of concrete.
  • Drilling out concrete cores for laboratory testing, preparation of specimens and testing in lab for determining compressive strength.
  • Tests for determining the depth of carbonation of concrete.
  • Half-cell potential tests for determining the likelihood of corrosion of reinforcement.
  • Tests for determining the chloride & sulphate contents in concrete.
  • Rebar locator tests for determining reinforcement details of various RCC members and concrete cover.

CONDITION SURVEY

Mapping defects in buildings, bridges and dams through rapid visual survey to plan NDT locations for effective testing.

PILE INTEGRITY TESTING (PIT)

PIT uses a small strain impulse technique that enables the integrity of piles to be established rapidly and economically.

CROSS HOLE SONIC LOGGING (CHSL)

CHSL is use to detect defects honeycombing; segregation; washout of cement; necking and arching such in concrete.
