Civil NDT Testing
Non-destructive testing services for concrete structures, evaluating strength, durability and internal condition without affecting structural integrity.
Civil NDT
Testing
Velciti provides Non-Destructive Testing (NDT) services for assessing the strength, durability and integrity of existing civil structures without causing damage to the member being tested.
Using calibrated diagnostic equipment, our engineers deliver reliable in-situ data on concrete quality, rebar condition and internal defects to support structural audit reports and repair decisions.
- Rebound Hammer & UPV Testing
- Rebar & Corrosion Mapping
- In-Situ Strength Estimation
- Pile Integrity Testing
- IS Code Compliant Reports
Comprehensive NDT Services
A complete suite of diagnostic tests to evaluate concrete strength, locate reinforcement, and detect hidden structural vulnerabilities.
Rebound Hammer Test
Estimates surface hardness and in-situ compressive strength using a calibrated Schmidt rebound hammer.
Ultrasonic Pulse Velocity (UPV) Test
Measures ultrasonic pulse velocity through concrete to assess uniformity and detect cracks or voids.
Core Cutting & Testing
Extraction of concrete cores from structural members to determine actual in-situ compressive strength.
Half Cell Potential Test
Electrochemical testing to assess the probability and extent of corrosion in embedded reinforcing steel.
Cover Meter Survey
Electromagnetic mapping to determine rebar location, spacing, diameter and concrete cover depth.
Carbonation Test
Phenolphthalein indicator testing on exposed concrete to determine carbonation depth and alkalinity loss.
Pull-Out Test
Evaluates bond strength and anchorage capacity between concrete and embedded reinforcement or anchor bolts.
Pile Integrity Testing
Low-Strain Pile Integrity Testing (PIT) to evaluate the continuity and integrity of cast-in-situ piles.
Key Deliverables
Actionable reports, detailed mapping, and structural health analytics ready for engineering interpretation and compliance submissions.
Comprehensive NDT Reports
Detailed documentation of all test results correlated with visual inspections and standardized testing codes.
Rebar Mapping Diagrams
Precise drawings showing the layout, spacing, and depth of existing reinforcement for retrofitting plans.
Corrosion Probability Charts
Color-coded contour maps derived from Half-Cell Potential data highlighting high-risk corrosion zones.
Strength Estimation Graphs
Correlation curves combining UPV and Rebound Hammer data for highly reliable in-situ strength assessment.
Defect Location Plans
Clear graphical mapping of internal voids, honeycombing, and delamination within the concrete matrix.
Pile Health Certificates
Reflectogram integrity profiles validating the structural continuity of cast-in-situ foundation piles.
Retrofitting Recommendations
Expert structural insights and repair strategies based directly on identified material deficiencies.
Code Compliance Verification
Structured assessments checking against IS 13311, IS 14893, and other relevant Indian testing standards.
Where We Apply It
From historic renovations to quality control on mega-projects, our NDT services cover all facets of civil infrastructure.
Aging Infrastructure
Structural health audits for old buildings and heritage structures to determine residual life and safety.
Post-Fire Assessment
Evaluating the extent of heat damage to concrete and reinforcement in fire-affected residential or industrial buildings.
Quality Assurance
Independent verification of concrete strength and reinforcement detailing in newly constructed structures.
Seismic Retrofitting
Providing baseline structural data essential for designing and executing earthquake-resistant building upgrades.
Bridge & Flyover Inspections
Periodic condition monitoring of critical transport infrastructure using UPV, Cover Meter, and Half-Cell testing.
Industrial Plants
Assessing the integrity of heavy machine foundations, silos, and chimneys subjected to dynamic loads or chemicals.
Marine Structures
Detecting chloride-induced corrosion and concrete deterioration in jetties, ports, and coastal infrastructure.
Deep Foundations
Verifying the integrity and continuity of bored cast-in-situ piles prior to superstructure construction.
