Non-Destructive Concrete Testing

Radar. Ultrasonic Pulses. Carbonation Testing.

Non-Destructive Concrete Testing covers a range of methods for testing the strength and durability of concrete structures without loading a specimen to failure or destructing the concrete.

Our accredited laboratories and mobile facilities are equipped to perform the following testing services according to testing standards set by ASTM, SANAS, BSI and more.

Non-Destructive

Concrete Testing

01


GPR
(Ground Penetrating Radar)

Our state-of-the-art Proceq GPR8000 is a non-destructive surface penetrating system that can measure the slab thickness as well as locate any of the following in concrete structures:

  • The re-bar locations and layout to help with as build drawings
  • Pre and post tensioned cables
  • Metallic conduits such as pipes, drains and water lines
  • Live wire detection

Once the scans are complete, we are able to provide a detailed condition report and images of the area noting any weaknesses in the structure to assist with construction quality control.


02


UPV
(Ultra-sonic Pulse velocity testing)

An ultrasonic pulse velocity (UPV) test is an in-situ, non-destructive test to check the quality of concrete. In this test, the strength and quality of concrete is assessed by measuring the velocity of an ultrasonic pulse passing through a concrete structure.


By doing so the following can also detected:

  • Honey combing
  • Slab thickness
  • Crack depths


03


Half-cell Potential
(re-bar corrosion)

The half-cell potential test is the only corrosion monitoring technique standardized by ASTM. It is used to determine the probability of corrosion within the rebar in reinforced concrete structures. This blog dives into the specifics of concrete corrosion, the half-cell potential technique for testing concrete corrosion, and the ways in which the datafrom the half-cell potential test can be interpreted.


04


Cover
meter

A cover meter is an instrument to locate rebar's and measure the exact concrete cover.


05


Carbonation
Testing

Carbonation of concrete is a process by which Carbon di Oxide from the air penetrates into the concrete and reacts with calcium hydro-oxide to form calcium carbonates. In the presence of moisture, CO2 changes into dilute carbonic acid which attacks the reinforcement and also reduces alkalinity of concrete.


06


Concrete
Coring

To establish the in-situ strength of the existing structures.
