Building Condition Survey, Structural Analysis and Audit

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.
