Papworths Construction Testing Service - NDT
Concrete Non-destructive Testing


Impact Echo

PCTS offer Impact Echo Thickness Certification, an acoustic non-destructive test method used to assess the dimensions and integrity of concrete and masonry.

Half Cell Potential

PCTS measure the potential of an embedded reinforcing bar relative to a reference half-cell placed on the concrete surface.

Schmidt Hammer

PCTS use Proceq Schmidt Hammers to measure the rebound value of a test impact on a structural member. PCTS can quickly and easily determine the compressive strength of hardened concrete and other construction materials.

Ultrasonic Pulse Echo

CTS offer Ultrasonic certification. UPE is a method for non-destructive evaluation of concrete. The output from the MIRA UPE testing equipment is shown on screen immediately after testing for on-site flaw detection.

PCTS - Experienced technicians, reliable results! We offer the very best value service when it comes to non-destructive testing.

Half Cell Potential Measurement

PCTS measure the potential of an embedded reinforcing bar relative to a reference half-cell placed on the concrete surface. The concrete functions as an electrolyte and the risk of corrosion of the reinforcement in the immediate region of the test location is related empirically to the measued potential difference.


CTS technicians are available to measure monitor and map concrete reinforcements potential for corrosion. This test can give the probability of corrosion activity taking place at the point where the measurements of potentials are taken from a half-cell, (typically a copper-copper sulphate half-cell).


CTS Technicians are available to:

  • Produce isopotential contour maps

  • Identify corrosion risk

  • Monitor expected corrosion

Ground Penetrating Radar

PCTS offer Reinforcement Mapping and Cover Certification.

PCTS use Ground Penetrating Radar technology to determine concrete cover as well as locate embedded reinforcement steel.

PCTS offer sub-surface imaging and reinforcement mapping on- site and in the form of a test certificate.

Electrical Resistivity Test

PCTS carry out Electrical Resistivity Testing using the Wenner Four Point Probe to assess the quality / uniformity of concrete at various depths.

Assessment of Cathodic Protection Systems

The Australian and European codes provide three criteria that can be used to determine if a cathodic protection system is compliant with the standard. The most commonly used protection criteria is a 100mv decay over 24 hrs from an instant off potential.

Ultrasonic Pulse Velocity

PCTS use Ultrasonic Pulse Velocity technology to measure the transit time of a pulse between transducers placed on the surface of a body of concrete.

The pulse velocity is then calculated using the measured path length through the concrete.
