Non-destructive tests (NDT) are inspection methods, which are usually used to search for the presence of defects in components, without causing any effects on the properties of the components. The type of defects detectable is cracks, porosity, voids, etc.

NDT Test Name

• Structural Survey of the building

• Rebound hammer

• UPV (Ultrasound Pulse Velocity Test)

• Core Cutting & Testing of core

• Cement contained Test

• Carbonation & Chloride content Test

• Soil Test

• Load carrying capacity test (Load Test)

• Brick Test ( water absorption & cussing strength)

• Steel (Dia & corrosion)

• Load carrying capacity of existing elements

• Inspection of earthquake impact/damage on structure

ULTRASONIC PULSE VELOCITY TESTING

Ultrasonic pulse velocity test consists of measuring travel time, T of ultrasonic pulse of 50 to 54 kHz, produced by an electro-acoustical transducer, held in contact with one surface of the concrete member under test and receiving the same by a similar transducer in contact with the surface at the other end.

INTEGRITY PILE TESTING

Pile integrity test covers the procedure for determining the integrity of individual vertical or inclined piles by measuring and analyzing the velocity (required) and force (optional) response of the pile induced by an (hand held hammer or other similar type) impact device usually applied axially and perpendicularly to the pile head surface.

GPR Scanning

GPR is used frequently in construction. Ground penetrating radar, or GPR, is used in construction every day, though you may not know it. Also known as ground surveying, GPR is a non-invasive, geophysical mapping method that uses radar pulses to image under the ground.
