We select the appropriate non-destructive test for your structure based on its suitability and its intended use.
Our objective is to assess existing condition of structure and provide recommendations based on findings.
Ultrasonic Pulse Velocity (UPV) Testing
ULTRASONIC PULSE VELOCITY (UPV) TESTING
Ultrasonic test on concrete is a recognized non-destructive test to assess the homogeneity and integrity of concrete. With this ultrasonic test on concrete, following can be assessed:
- Homogeneity or uniformity of concrete in structures, post construction to check for voids, honeycombs etc.
- Qualitative assessment of strength of concrete, its gradation in different locations of structural members and plotting the same.
- Any discontinuity in cross section like cracks, cover concrete delamination etc.
- Depth of surface cracks.
This is a standard ASTM test classified under ASTM C 597 – “Standard Test Method for Pulse Velocity through Concrete”

Corrosion Mapping
Half Cell electrical potential test is used to detect the corrosion potential of uncoated reinforcing bars embedded in concrete.
The test is used to determine the corrosion activity of reinforcement bars in concrete structure, which is an indicative of permeability of concrete.
This is a standard ASTM test classified under ASTM C 876 – “Standard Test Method for Half-Cell Potentials of Uncoated Reinforcing Steel in Concrete”
Floor Elevation Survey
FLOOR ELEVATION SURVEYS
C3S helps its clients like attorneys, property owners/managers, insurance companies and other private companies/individuals performing Foundation and Floor Elevation Surveys/Studies to study slab-on-grade or foundation movements.
C3S presents data in form of 2D or 3D survey maps that helps clients to identify and isolate source of problem and consecutive repair strategies by mapping structural movements.

Ground Penetrating Radar (GPR) Scanning
C3S provides ground penetrating radar scanning services which is a reliable, non-destructive means to locate targets within concrete structures prior to drilling, cutting or coring. By performing GPR on concrete, following can be assessed:
- Slab Thickness
- Concrete Cover and Rebar Location
- Voids – Location and Extents.
- Pre Stressing Strands (PT Cables)
- Conduits
This is a standard ASTM test classified under ASTM D6432 – “Standard Guide for Using the Surface Ground Penetrating Radar Method for Subsurface Investigation” ( Section 1.1.2, point 11)
To complement our GPR service, we can also determine rebar size using the latest technology.

Other NDT Tests
OTHER AS NEEDED NON DESTRUCTIVE TESTING
C3S provides some other as-needed Non Destructive Testing to examine the hardened concrete structure for their suitability for its intended use:
There are various NDT tests available for concrete structures, but based on its suitability and applications they are selected
If you have identified a defect and need an assessment of the extent and severity, we will be able to help.
Schedule a consultation or inspection today.
Experience Matters
- In-depth knowledge of a range of NDT methods and field experience on several projects enable us to deliver needed service.
