NABL accredited NDT assessments for existing concrete structures — rebound hammer, ultrasonic pulse velocity (UPV), and cover meter surveys across Bengaluru.
When you need to evaluate concrete quality in existing structures without causing damage, non-destructive testing (NDT) is the answer. V2 Civil Diagnostics offers three core NDT methods — Schmidt rebound hammer for surface hardness and estimated compressive strength, ultrasonic pulse velocity (UPV) for concrete uniformity and defect detection, and cover meter surveys for rebar location, depth, and diameter measurement. Our NDT team travels to construction sites across Bengaluru for on-site assessments. All testing follows IS 13311 procedures under NABL accredited, ISO/IEC 17025:2017 protocols.
Our comprehensive testing covers all essential parameters required by Indian Standards and NABL protocols.
| Method | What It Measures | IS Code |
|---|---|---|
| Ultrasonic Pulse Velocity (UPV) | Concrete uniformity, crack depth, quality grading | IS 516 Part 5 Section 1 |
| Rebound Hammer Test | Surface hardness, estimated compressive strength | IS 516 Part 5 Section 4 |
| Half Cell Potentiometer Test | Corrosion activity of embedded reinforcement | IS 516 Part 5 Sec 2 |
| Carbonation Test | Depth of carbonation front in concrete | IS 516 Part 5 Sec 3 |
| Cover Depth & Reinforcement Detailing | Rebar location, concrete cover depth, bar diameter | BS 1881 Part 204 |
Non-destructive testing (NDT) evaluates concrete quality, strength, and rebar placement without damaging the structure. It is used for quality audits, structural assessments, and condition surveys of existing buildings and infrastructure in Bengaluru.
V2 Civil Diagnostics offers on-site NDT services across Bengaluru. Our NABL accredited team brings calibrated equipment to your construction site for rebound hammer, UPV, and cover meter assessments.
The rebound hammer estimates surface compressive strength based on rebound number. UPV transmits ultrasonic waves through concrete to assess internal quality, uniformity, and detect voids or cracks. Both tests are often used together for a comprehensive assessment.
NDT provides indicative results — it is a screening tool, not a direct measurement of compressive strength. If NDT results raise concerns, core testing per IS 516 Part 4 is recommended for definitive strength verification. We offer both services.
A typical NDT assessment for a single floor or structural element takes a few hours on site. Larger structures or full-building surveys may require one or more days. We provide a time estimate when you share your project scope.
Yes. Our NDT reports are issued under NABL accredited, ISO/IEC 17025:2017 protocols and are accepted by BBMP, BDA, and other regulatory bodies for structural audit and compliance purposes.
