sectional area, length, continuity, and consistency of the pile material
Pile Integrity Test (Pulse Echo Method )

18. This test method concerns the
measurement of in-situ
masonry deformability
properties in existing masonry
by use of thin, bladder-like flat
jack devices that are installed in
saw cut mortar joints in the
masonry wall.
Applications –

Compressive strength of
masonry
Flat Jack Test

19. The Timber Resistograph helps evaluating historic and modern timber
structures and is the base for repair planning.

problematic / in-accessible areas where bear minimum destruction is
allowed for inspection such as –
• Concrete pipes,
• Water Pipes
• Storm pipes
• Sewer Lines,
• Culvert
• Cavity walls,

Drone Camera

24. A very useful tool in the structural audit / survey. In most of the
Industries, especially in Chemical factories corrosion is a very
serious issue for the structural stability of the structural steel
structures, M S Chimney , Stacks, Gantry girders, Pipe racks,
Pipelines etc.
Using the Ultrasonic thickness Gauge we can find out the precise
thickness of all such steel / metal structures, components .
Ultrasonic Thickness Gauge

25. Moisture is known to be one of the main source causing
deterioration of masonry and timber structures. To identify
the source of leakages and dampness moisture meters are
very helpful. If the concrete, masonry , timber structures are
found to be wet, then appropriate repairs can be carried out
to avoid further decay / deterioration of the material and
structure as a whole.
Moisture Measurement

26. Many a times Load test is carried out on building & Bridge components
when –
• As a proof of Structural Adequacy.
• The strength of concrete is below the acceptable norms
• Structural Design data is not available.
• Load carrying capacity of the flexural member needs to be assessed.
• The members is to be subjected to a higher loads
• The members are noticed to have cracks, deflections
• The structure is damaged due to fire, earthquake, blast, corrosion
etc.
• Change in use of structure.
• NDT or Core tests indicate a lower strength.
Load Test

27. According to Government regulations, all
factories and residential societies are
expected to undergo assessment and
