Infrared Thermometers – Used in combination with Moisture meters to identify the temperature gradient and spot temperatures from a long distance by just sighting the object., a very useful tool in structural audits of the buildings, water structures, chimney etc.

Load Test – Performance acceptance test for flexural members like slab, beams and & Bridges

Carbonation , Sulphate / Chloride Content tests

Calibration of Rebound Hammers

Non Destructive Testing

Different Rebound Hammers along with Calibration Anvil

The rebound hammer method is used for Assessing –

• Surface compressive strength of concrete.• Uniformity of concrete• Quality of concrete.

We have a very wide range of Rebound Hammers including Digital 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 time

We 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 walls

Our Core cutting machines can extract cores of different diameter ranging from 25 to 300 mm and upto 1 m long

Core Test / Core Cutting

• Detection of Reinforcing bars from concrete members, where RCC drawings 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 of deterioration of concrete structures at the present time. Both of these tests 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 the condition of piles or shafts. It is cost effective and not very time consuming.

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 )

Structures / buildings can get a vibration from sources such as Blast, Mining activity, Piling work, Machinery imbalance, Road / Rail / Metro traffic, Wind, Impact etc. Our Vibration Meter can measure Peak and Instantaneous Velocity, Acceleration and Displacement

We 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 identifying problematic / in-accessible areas where bear minimum destruction is allowed for inspection such as –

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

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

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

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

According to Government regulations, all factories and residential societies are expected to undergo assessment and obtain a Structural Stability Certificate from a chartered civil engineer, every 5 years.

We are the competent authority to provide such certification. We offer services including detailed inspection, assessing the strengths & weakness of the structure, conducting NDT, preparing repair / rehabilitation scheme, monitoring repair work and issuing Structural Stability Certificate.

Structural Audit & Stability Certification

Structural Audit – Why and When

The 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 after

every 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 observed to be in a distressed condition. The structures may require repair / 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
