Quick overview of all services

Rebound hammer and UPV have become synonymous with NDT. These are quick and easy tests for estimating the quality of RCC For increased accuracy, we have an advanced UPV machine and digital rebound hammer. Data visualization through graphs,
charts and contour diagrams

For those who understand corrosion, HCP and carbonation are just the bare minimum We have an entire vertical that specializes and researches in durability and corrosion Obviously, the instruments we use are state of the art and are minimally invasive. Clear mapping of corrosion potential, concrete resistivity and rate of corrosion is now possible

Durability goes deeper than what is visible on the steel and concrete So at the macro-scale our tomography machine catches the voids, cracks and delamination. At micro scale, we need more than just chemical composition Such as chloride profiling, petrography and
so forth.

A lot goes into extracting a core the right way, without affecting the structure. A lot more goes into dressing and testing it the right way, to get standardized results. With cut and pull-out test (CAPO) and surface pull-off adhesion test (POSI), true interaction parameters of concrete can be assessed, which are critical for designing strengthening applications.

Even when structural drawings are not available, our advanced ground penetrating radar scanners can help arriving at good estimates of total rebar area in RCC members. Locating rebars before core cutting or for establishing contact for tests like half-cell potential can be reliably done by our elcometers and bar locators.

For what is not possible with visual inspection, we have drone survey, 3D lidar scanning, endoscopic scanning and thermographic survey. Historic restorations, as-built drawings, leakage assessments, façade inspections and bridge girder inspections could now be done with ease and satisfaction, and with meticulous detail.

Workmanship matters more in steel than in RCC, as the design codes allow for smaller FOS. Whether it is quality of weld, gauge of the structural element or the hardness of the material, our team can inspect, test, quantify and report all the necessary parameters, with the necessary photographs, drawings and visual data representations.

SHM is gaining importance as the true test of performance of a structure in practical dynamic loading. Our handpicked range of diverse sensors and high frequency acquisition systems have proven their dynamic monitoring capabilities on railway bridges. Coupled with our inhouse FEM expertise, digital twinning & modal analysis is a breeze. Every vibration, tilt, strain and deflection of your structure has a story to tell, let’s listen to it.

Vijna takes a deep-dive into the enigmatic realm of underwater piers, piles, and well-foundations, unveiling the cracks and cavities that are hiding from plain sight, with crystal clear visuals, underwater NDT, geo tagging, quantification of distresses and a dashboard to see them all. We also perform bathymetric survey, 3D sonar and scour analysis.

Assessing the true impact of a fire requires meticulous understanding of various parameters, such as ventilation, the presence and types of combustible materials, fire duration, temperatures reached, concrete cover depth, design safety factors and more. Also, with the advanced concrete tomography tool, we could peer into the depths of distressed concrete to see the cavities and internal cracking that may have formed due to fire.

What makes us truly stand-out among the others in the field? Our in-house team of experienced engineers and top academicians who specialize in structural retrofitting of civil structures. We are essentially the top structural troubleshooting agency you can find in India. We seamlessly integrate our structural analysis capabilities with our NDT (Non-Destructive Testing), SHM (Structural Health Monitoring), and Durability verticals.

Backed by our technical knowhow, familiarity with relevant Indian codes/guidelines and experience of hundreds of full-load testing projects, Vijna stands tall among others when it comes to restoration of your trust on a structure, through full-scale load testing. We have 100+channel dynamic and portable static DAQs with IP68 rated LVDTs, Japanese strain gauges, imported accelerometers, etc

The tell-tales of foundation settlement may get missed out from distress mappings, since they typically form in non-structural elements. Which is why when in comes to structural audits and assessments, there is no substitute to the expertise of Vijna. From inspection to analysis and remediation methods, we tune in the full spectrum of foundation settlement for you, so that major decisions can be made confidently.
