C3S Concrete Non Destructive Testing Services

Concrete Non-Destructive Testing Methods, Benefits, Applications and Their Role in Structural Integrity Evaluation.

Concrete Non Destructive Testing

At C3S, Inc., we choose the right non destructive testing method based on your structure’s needs. Our assessments reveal hidden defects, evaluate damage, and ensure quality for both new and older structures, offering comprehensive internal and external condition evaluations.

Ultrasonic Pulse Velocity Testing

Ultrasonic Pulse Velocity (UPV) testing is a non-destructive method for assessing the integrity of concrete or stone up to 6 feet thick. It measures ultrasonic wave speed, revealing density variations and enabling the creation of tomographic images of defects.

Corrosion Mapping

The Half Cell Potential (HCP) method is a non-destructive technique for monitoring corrosion in reinforcing steel embedded in concrete. It measures electrical potential from electrochemical reactions, helping locate active corrosion areas.

Floor Elevation Surveys

C3S, Inc. specializes in Foundation and Floor Elevation Surveys to analyze slab-on-grade and foundation movements. By producing detailed 2D and 3D survey maps, C3S helps clients visualize structural changes. These maps are invaluable for identifying and isolating the root causes of issues, enabling clients to develop targeted and effective repair strategies tailored to their specific situations.

Concrete Non-Destructive Testing Methods, Benefits, Applications and Their Role in Structural Integrity Evaluation.

Concrete Non Destructive Testing

We select the appropriate non destructive testing 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.

Concrete Non Destructive Testing condition assessment investigations can quickly uncover hidden construction defects, assess unknown features, and determine the extent of damage caused by catastrophic events. These investigations are performed on newer structures for quality assurance purposes and on older structures for repair, rehabilitation and/or renovation purposes. Non Destructive Testing methods can test on a variety of surfaces and structures. At C3S, Inc., we provide visual external condition assessment, detailed internal condition assessment, and destructive correlation testing services.

Ultrasonic Pulse Velocity Testing

Ultrasonic Pulse Velocity testing measures wave speed in concrete, assessing integrity and creating tomographic defect images.

Ultrasonic Pulse Velocity Testing on concrete is a recognized non destructive testing to assess the homogeneity and integrity of concrete. With this ultrasonic test on concrete, the following can be assessed:

  • ๏˜Homogeneity or uniformity of concrete in structures, post construction to check for voids, honeycombs, cracks or other defects.
  • ๏˜Identify areas of low-quality concrete.
  • ๏˜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. We can define the size and shape of a defect by using multiple test paths.

ASTM C 597 covers Pulse Velocity testing. Sonic Pulse Velocity (SPV) assesses materials over 6 feet, testing concrete, stone, or wood up to 25 feet thick, including large columns and beams.

Corrosion Mapping

The Half Cell Potential (HCP)ย method is non destructive testing used when monitoring the corrosion activity, resistivity, and rate of reinforcing and other structural steel elements embedded in concrete. This is an electrochemical technique used to locate areas of active corrosion of steel reinforcement in a concrete slab or wall. The HCP method takes advantage of the oxidation-reduction (redox) chemical reaction from active corrosion that produces an electrical potential that can be measured externally. The corrosion activity of reinforcement bars in concrete structure is an indicative of permeability of concrete.

This is a standard ASTM test classified under ASTM C 876 โ€“ โ€œStandard Test Method for Half-Cell Potentials of Uncoated Reinforcing Steel in Concrete

Ground Penetrating Radar Scanning

This non destructive testing procedure utilizes a portable radar unit to determine the location and depth of steel reinforcement embedded in concrete, thickness of concrete members, presence of voids within or beneath a concrete slab, and assessment of the general uniformity of the concrete.

C3S offers reliable ground penetrating radar scanning to locate targets in concrete before drilling or cutting.

  • ๏˜Slab Thickness
  • ๏˜Concrete Cover and Rebar Location
  • ๏˜Voids โ€“ Location and Extents
  • ๏˜Pre Stressing Strands (PT Cables)
  • ๏˜Conduits

This standard ASTM test falls under ASTM D6432 for subsurface investigation using GPR.

We determine rebar size with technology.

Additional Non Destructive Testing

C3S provides some other as-needed Non Destructive Testing. There are various NDT tests available for concrete structures, but they are selected based on suitability and application.

Visual Inspection

Visual inspections provides information on type, extent of damage, their possible causes and type of NDT test suitable for further investigation.

Carbonation Depth Measurement Test

This NDT is used to determine the penetration of agents of corrosion like moisture inside concrete. Its identified using Phenolphthalein indicator and is vital to assess if corrosion level has reached to the level of rebar in a structure.

Schmidt Rebound Hammer Test

This is used to evaluate of surface hardness of concrete structures. The surface hardness of concrete is usually an aspherical indication of strength of concrete (not accurate).

C3S IS A GLOBAL LEADER IN CONCRETE EVALUATION

We deliver high-quality services that our customers have come to rely on and expect consistently.
