PCTE's blog about the world of NDT, started in August 2011 in this format we are extremely proud of the articles and information that we have produced internally and those that have been shared by our partners, suppliers and customers.

Basic Procedure of Performing the California Bearing Ratio (CBR) Test

CBR stands for California bearing ratio; It is the penetration test which is used to evaluate the mechanical adaptability of the soil mass in the natural ground level. See more here...

5 Typical Applications of VW piezometer

VW Piezometer (where VW stands for Vibrating Wire) is an apparatus constructed a diaphragm, tensioned steel wire, and an electromagnetic coil. It is used to measure the water pressure. See more here...


Utilities refer to the conduits present underground which are usually meant to transport gas, electricity and water. During construction, before any kind of excavation can begin, it is necessary to check if there are any utilities running beneath in order to not damage them. See more here...


Concrete has come forward as one of the most widely used materials for construction. The fact that it has great compressive strength makes it the preferred material for all kinds of structures. There are many grades of concrete available which have varying strengths. See more here...


Technology today has penetrated into all the industries to such an extent that there is no on-site problem that cannot be solved. Right from reconnaissance to final touches, every activity across all industries rely on various equipment to guide them to do a good job. See more here...


Construction of a building begins below ground level – because that is where foundations are made. Foundations support the load of the entire building, and that is why every measure is taken to make sure that they are constructed right. See more here...

Maintaining Standards with Utest Lab Equipment

One of the really interesting processes required when taking on a supplier like Utest has been the work we’ve done to customise their range for the Australian Market. See more here...

GPR and Post Tensioning Scanning 

Ground Penetrating radar is the right tool to locate post tension tendons inside a structure, but operators need to be aware of the differences from regular scanning. 

Coating Thicknesses on Concrete Using Positector 200 Gauge

Coating thicknesses on concrete are straightforward to measure, but it is important to understand the tools and how they work.

Congratulations Reuben!

Our head honcho Reuben recently attended the Concrete Institute of Australia's WA Branch Seminar, read more about it...

An Introduction to Ground Penetrating Radar

We introduce Ground Penetrating Radar.

How to Cure Concrete and Developments in GPR

This blog post discusses concrete curing in Australia and looks at a case study on the developments in GPR software.

How to Locate Defects in Concrete

We look at the non-destructive testing methods that can be used to locate defects in concrete as well as some of the basic methods for processing GPR data.

Benefits of the Cover Meter System in Pre-Cast Yards

The first blog post for 2017 discusses the Defelsko Positector range along with the benefits of cover meter system in pre-cast yards. 

The Benefits of the LMX-200 GPR

This blog is discussing the use of the LMX-200 GPR with GPS data and Google maps and presenting a case study on structural monitoring using vibrating wire crack meters. 

Standards of Non-Destructive Testing Equipment

We look at confirming testing equipment meets a standard and a detailed case study of meeting the ASTM F2170 standard for humidity testing of concrete.

Corrosion Monitoring and Light Weight Deflectometers

To support corrosion investigation works one of our articles this month talks about tools for corrosion monitoring. We also discuss the benefits of Light Weight Deflectometers in evaluating pavement systems.

Analysis of Raw Data from GPR and a Cover Meter

In our final blog post for the year we are looking at raw data from two systems, GPR systems for utility location and the raw magnetic measurements from a cover meter. 

How to Monitor Temperature of Bulk Concrete Pours and the Silver Schmidt Hammer

We have two topics for this issue: one for temperature monitoring of bulk concrete pours and the other focusing on the Silver Schmidt Hammer and converting its Q value results to R values common to older correlation curves built using an Original Schmidt.

Technical Overview of Compression Machines and How to Locate Post Tensioning With GPR Systems

Our articles this month are a technical overview of compression machines and force measurement and a case study on locating post tensioning with GPR systems.

How tdo a Concrete Cover Check

As more and more quality assurance specifications require concrete cover checks nowadays, we will give you a comprehensive overview of how to carry them out properly. We will also present an extract from our Australasian Tunnelling Society conference paper on geotechnical instrumentation of tunnels.

What is Impact Echo Testing and I Dumitru’s Paper Results

We discuss the finer points of impact echo testing for shallow foundations, along with a summary of the results of I Dumitru's paper on the effects that grinding cylinder ends before compressive testing compare with results from cylinders that are sulphur or rubber capped.

Focusing on Ultrasonic

Ultrasonics is the focus for this blog post, looking at ultrasonic pulse echo data processing, along with the regular sound wave sister to ultrasonic pulse velocity, sonic pulse velocity testing.

Investigating Corrosion Monitoring and Half-Cell Potential

Once again this issue overlaps with the Australian Corrosion Association's conference. Discussed topics include Corrosion Monitoring and Half-cell potential investigations. 

Structural Health Monitoring and Geotechnical Testing

Structural Health Monitoring and Geotechnical Testing take centre stage in this post. There is also a vibrating wire sensors case study. 

Tips and Hints for Completing a Successful Testing Job and How to Measure Concrete Thickness

With a new year, our blog went back to basics, discussing hints and tips for successful completing of any testing job, the role of standards and an in-depth analysis of different testing methods that can be used for concrete thickness measurements. 

Resistance and Resistivity

This blog post overlaps with the Australasian Corrosion Association’s annual conference, it features a revised article on Resistance and Resistivity and some information on state of the art ground penetrating radar technologies for corrosion investigation

Pile and Foundation Tests

In our first issue for 2012 we focus on pile and foundation tests, with a fantastic case study and technical overview of Sonic Echo/Impulse Response testing and quick overview of the other tests that can be applied to this broad area of testing.

All Things Corrosion

This blog post in 2011 lined up with 18th International Corrosion Congress and to celebrate we focused upon all things corrosion. We talk about corrosion monitoring and investigation and look in detail at Concrete Resistivity as a quality assurance tool.

How to use the Reb-Ultra method of Testing

In this issue we look at strength testing using the Reb-Ultra method which combines ultrasonic testing and rebound hammer testing. Secondly, we look at the challenges of locating footing and some of the equipment that can be used to assist the hunt.
