NDT-Non Destructive Testing Lab
Non-destructive testing (NDT) evaluates the strength and integrity of existing concrete structures without causing physical damage to the element under test. Structural engineers and quality auditors rely on NDT to assess whether in-service buildings, bridges, and columns meet design standards. Skipping certified NDT on a project with structural concerns can result in rejection by approving authorities, costly rework, and serious legal liability for the contractor.

WHO WE SERVE
Jancy Labs provides NABL-accredited NDT reports to the following departments and organisations that work with existing concrete structures:
Building & Housing Authorities
- CPWD — Central Public Works Department (structural audits, rehabilitation assessments)
- TNHB — Tamil Nadu Housing Board (quality audit of existing stock)
- CMDA / DTCP — Statutory approvals for building compliance
- MES / BRO — Defence infrastructure, border road structures
Infrastructure & Urban Bodies
- PWD Tamil Nadu — Bridge and road overpass structural assessment
- Smart Cities / ULBs — Urban infrastructure audit and retrofitting projects
- TIDCO / SIDCO — Industrial shed and warehouse structural evaluation
Energy & Industrial Projects
- TANGEDCO — Power plant structure integrity testing
- NTPC / BHEL — Large-scale industrial concrete structure evaluation
Consequently, submitting NDT reports from a non-NABL lab to any of these departments risks outright rejection, tender disqualification, and costly re-testing. View all our concrete testing services.
