Timber Inspection

Timber inspection has been an art form more than a science until now. The founding members of Revo Group have been actively seeking out, developing and using NDT techniques for the inspection of wood poles, piles and structural members for more than 20 years.

What we realised was twofold:

There is no one single inspection technology that can be used effectively and economically on its own to inspect wooden structures.

The existing techniques, when combined, could complement each other to provide a range of accurate services covering the range of cost effectiveness required.

At Revo Group, we recognise that every structure, and every organisation is different in terms of what works best for them, based on their specific issues, species, design, constructions, etc.

As such, we bring together the expertise required to provide tailored solutions to any aspect of your system. A significant part of that is our ability to provide the NDT Toolkit, and to design inspection processes that can include any number of elements of the toolkit, other supplier’s technology, or in some cases, no NDT at all (although this requires considerably more expense for the same level of reliability).

After rigorous testing and experience, PortaSCAN® was selected as the tool of choice for timber inspection:


The PortaSCAN® is a portable density gauge that identifies variations in wood density. It is a safe, quick and simple tool used to assist inspectors in understanding what lies beneath the surface of the timber they are examining.

Poles can be inspected full height from the ground, and we can also inspect crossarms from the ground to look for hidden defects.

It is also applicable for practically any other wooden structural element (CLT, beams, piles, girders, corbels, plywood, etc.)

The output is immediately available to the inspector and can be recorded for later retrieval. This means that where a defect is located the operator can focus on that section to further quantify its size and effect on structural stability.

We all know the outer wall strength of poles is what is important, and this is where PortaSCAN® excels. With a scanning depth of up to 100mm, it is not only incredibly accurate but can provide a cross-section strength estimate in just 40 seconds. Defects are treated conservatively in strength calculation.

This technology gives a more detailed picture of the cross-section where there is an issue, and where it is accessible. It can detect the gamut of strength-loss mechanisms.
