Need of NDT
The need of testing hardened concrete has been felt for a few decades. The present methods of testing fresh concrete such as cube test, slump test are now being supported by various Non Destructive Testing methods. To assess the integrity of old or new concrete and reinforcement, Non destructive testing is one of the most powerful and reliable tools. The need of conducting non destructive testing for condition assessment of the RCC structures has grown considerably in recent times, due to increase in number of structures, showing signs of distress.
The Non Destructive Testing is being fast, easy to use at site and relatively less expensive can be used for
- Test actual structure instead of representative cube sample
- Test any number of points and any locations
- Quality control tool
- Assess the structure for various distressed conditions
- Damage assessment due to fire, chemical attack, impact, age etc.
- Detect cracks, voids, fractures, honeycombs and week locations
- Monitor progressive changes in the properties of concrete , reinforcement etc.
- Assess overall stability of the structure
- Monitoring repair and rehabilitation systems
- Scanning for reinforcement location, stress locations.
We have a full range of NDT instruments and conduct tests such as
- Rebound Hammer Test – To assess the quality and strength of site concrete
- Ultrasonic Pulse Velocity Test – To assess the quality and strength of site concrete
- Concrete Core Extraction – To assess the strength of site concrete, Making holes in RCC for Plumbing / Electrical purpose
- Ground Penetrating Radar(GPR) – Locating Reinforcement, defects in the concrete, Masonry. Locating Utilities , objects underground.
- Rebar Location & Cover-meter – Locating Reinforcement in the concrete.
- Half-Cell Potential Test – for reinforcement corrosion mapping
- Concrete Resitivity Test – for reinforcement corrosion mapping
- Pile Integrity Test – For assessing the integrity, continuity & depth of pile
- Flat Jack Test – For assessing the compressive strength, stress level of Masonry
- Micro-Drill Resistance Test – For assessing the Integrity of Timber
- Vibration Measurement – For measuring Displacement, Velocity & Acceleration of civil structures.
- Endoscopy / Bore scope – To inspect the in-accessible areas of structures , building components, Heritage structures, pipes
- Underwater Inspection – To inspect underwater structures such as Bridge piers, Columns, Pile foundations, Dam walls, Water tanks, Water Treatment plants, Effluent Treatment plants. No need of Divers. Get a good quality Image and Video by a professional underwater camera.
- Crack Inspection–Measurement of crack widths by high zoom high resolution crack scopes
- Load Test – Performance acceptance test for flexural members & Bridges
- Ultrasonic Thickness Gauge – For metal plates, pipes
