Non Destructive Testing

Different Rebound Hammers along with Calibration Anvil

The rebound hammer method is used for Concrete, Mortar & Bricks for assessing –• Surface compressive strength• Uniformity• QualityWe have a very wide range of Rebound Hammers includingDigital Rebound Hammer

Rebound Hammer Test

The ultrasonic pulse velocity method is used to assess• The Quality / Compressive strength of concrete.• The homogeneity of the concrete• The presence of cracks, voids and other imperfections, depth of crack• Changes in the structure of the concrete which may occur with timeWe have a very wide range of UPV machines with different frequency &different sizes probes, capable of scanning concrete upto 10 m wide

Ultrasonic Pulse Velocity Test

• Determining “In situ” compressive strength of structure.• Small cores for chemical tests like pH, Carbonation, Sulphate &Chloride Content etc.• Measuring Density, Water Absorption• Identifying defect like Cracks, Voids, Honeycombing etc.• Inserting water supply, plumbing , electrical pipes• Making pockets for machine foundation for inserting bolts• Making weep holes in wallsOur Core cutting machines can extract cores of different diameterranging from 25 to 300 mm and upto 1 m long

Core Test / Core Cutting

The state of Art Technology• 3D imaging ( Tomography ) of shallow and deep rebars in concrete;• Inspection of concrete for location of voids, internal defects,delamination and cracks• Inspection of concrete thickness, integrity;• 3D imaging of pre-tension and post-tension cables;• Inspection and analysis of old structures and monuments;• Inspection of walls and floors for the location of pipes, objects,caches, etc..

GPR – Ground Penetrating Radar

• Detection of Reinforcing bars from concrete members, where RCCdrawings are not available.• Detecting bars for Core drilling, fixing anchors• Detecting cover to the reinforcement along with carbonation test

Rebar Locator

Corrosion of embedded steel is probably the major cause ofdeterioration of concrete structures at the present time. Both of thesetests are very useful to identify the corrosion.Applications –• Determination of Corrosion Activity of the reinforcing steel• Determination of likelihood of corrosion or corrosion risk

Half – Cell Potentiometer & Resistivity Test

Different Half-Cell Potentiometers

Half – Cell Potentiometer & Resistivity Test

Wenner 4 probe - Concrete Resistivity Meter

A pile integrity test is one of the advance methods for assessing thecondition of piles or shafts. It is cost effective and not very timeconsuming.Applications –• Evaluation of Pile integrity and pile physical dimensions i.e. cross-sectional area, length, continuity, and consistency of the pile material

Pile Integrity Test (Pulse Echo Method )

This test method concerns themeasurement of in-situmasonry deformabilityproperties in existing masonryby use of thin, bladder-like flatjack devices that are installed insaw cut mortar joints in themasonry wall.Applications –• Determination of the averagecompressive stress in existingmasonry• Assessing the in-situCompressive strength ofmasonry

Flat Jack Test

The Timber Resistograph helps evaluating historic and modern timberstructures and is the base for repair planning.Applications –• Assess the condition of structural timber and joints• To identify voids, decay, insect damage, and cracks in the Timbermembers

Micro-Drill Resistance of Timber

Structures / buildings can get a vibration from sources such asBlast, Mining activity, Piling work, Machinery imbalance, Road /Rail / Metro traffic, Wind, Impact etc. Our Vibration Meter canmeasure Peak and Instantaneous Velocity, Acceleration andDisplacementWe carry out Vibration Measurement for –• Buildings / Structures• Bridges,• Chimney / Stacks• Water Tanks• Heritage Structures

Vibration Measurement

Bore scope Survey / Endoscopy Endoscopy surveys provide a fast, cost effective means of identifyingproblematic / in-accessible areas where bear minimum destruction isallowed for inspection such as –• Concrete pipes,• Water Pipes• Storm pipes• Sewer Lines,• Culvert• Cavity walls,• Air ducts, Vents,

• Chimneys,• Ceiling, roof and floor voids,• Water tanks,• Heritage structures,• Timber structures,• Concrete or Masonry structureswith large voids, honeycombingetc.

Bore scope survey – Boiler Tube

We carry out underwater inspection of structures like –• Dams• Bridges• Water Tanks• Effluent & Water Treatment Plants• Jetty• Underwater Structures

Underwater Investigation

Corrosion of Underwater Structures captured by CameraUnderwater Camera

We Have sophisticated Drone Camera for the inspection ofstructures like –• Over Head Water Tanks• Tall Structures• Chimney• Bridges• Silo

Drone Camera

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

Ultrasonic Thickness Gauge

Moisture is known to be one of the main source causingdeterioration of masonry and timber structures. To identifythe source of leakages and dampness moisture meters arevery helpful. If the concrete, masonry , timber structures arefound to be wet, then appropriate repairs can be carried outto avoid further decay / deterioration of the material andstructure as a whole.

Moisture Measurement

Many a times Load test is carried out on building & Bridge componentswhen –• 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, corrosionetc.• Change in use of structure.• NDT or Core tests indicate a lower strength.

Load Test

According to Government regulations, allfactories and residential societies areexpected to undergo assessment andobtain a Structural Stability Certificatefrom a chartered civil engineer, every 5years.We are the competent authority toprovide such certification. We offerservices including detailed inspection,assessing the strengths & weakness ofthe structure, conducting NDT, preparingrepair / rehabilitation scheme,monitoring repair work and issuingStructural Stability Certificate.

Structural Audit & Stability Certification

Structural Audit – Why and WhenThe Structural Audit is carried out mainly for -• As a statutory requirement –

– After every 5 years as per Inspector of factories– After 15 years at every 5 years and after 30 years afterevery 3 years as per Municipal Act

• For Insurance• For Bank – Mortgage• For Valuation• Structure showing Distress• Proposed Additions , Alterations , Extensions in building/ structure• For Damage assessment due to earthquake, fire, blast,vibration, corrosion etc.

Structural Audit & Stability Certification

In recent times, a large number of structures are observedto be in a distressed condition. The structures may requirerepair / rehabilitation due to –• Poor quality concrete / workmanship• Construction Deficiencies• Design Deficiencies• Severe Exposure Condition• Corrosion• Aging• Damage due to Earthquake , Fire, Blast, Vibrations etc.• Settlement , Foundation problems
