TreeRadar Ground Penetration Radar


    TreeRadar GPR (Ground Penetrating Radar) provides a cost-effective, non-invasive tree root and tree decay investigation with minimal fuss and maximum results.


    TreeRadar™ GPR, is the leading tree investigative tool for tree root mapping and decay investigation. It is also often referred to as a ‘root radar’ or ‘tree radar’. TreeRadar GPR can detect sub-surface infrastructure through grass, tarmac and concrete. It is the quickest, cleanest, completely non-invasive and the most cost effective root detection equipment available. For tree decay detection TreeRadar is a fast, accurate and cost-effective alternative to Picus and additionally provides sound wood predictions.


    How does TreeRadar GPR work?

    Non invasive Root investigations

    TreeRadar GPR collects data on the electromagnetic differences between artefacts and strata below ground to determine the depth and location of tree roots and other items including buried objects and services such as pipes, cables and ducts. These are recorded in the GPR tree survey field computer on site. At PBA Consulting our industry-leading tree consultants are able to interpret survey findings to give informed recommendations supported by TreeRadar™ analysis and ‘radargram’ printouts.


    Tree Root Mapping and Accurate Root Location

    By using a TreeRadar GPR survey you can determine the health and breadth of your vegetation without disturbing any sub-surface infrastructure. The trenchless sub-surface investigations provide you with information on root morphology (tree root mapping) and root zone conditions including buried artefacts and services.


    Working within Root Protection Areas (RPAs)

    As part of BS5837 Tree Surveys, TreeRadar GPR surveys can provide scans of the location, spread and depth of tree roots related to RPAs to support planning applications.

    The high degree of accuracy provided by a TreeRadar GPR tree survey means that root depth and position can be detected and used to guide the installation of services and specialist foundations – i.e. short-bore piles or similar elements between and under roots.


    Non-invasive Tree Decay Detection

    TreeRadar GPR surveying provides a totally non-invasive option for detecting tree decay. It is used by arboriculturalists to assess the risk to trees’ structural integrity, which may have been compromised as a result of decay.

    By using electromagnetic waves, the different properties of decayed and sound wood can be determined and mapped on a radargram. This tree decay detection technique can be used to investigate decay high in the tree canopy on scaffold branches, the main bole and in buttress roots.



    PBA Consulting is committed to on-going research and has conducted a range of trials and investigations in the UK to aid TreeRadar Inc in the USA to develop the accuracy of their software. Our research has also included the tracing of invasive weed roots of Japanese knotweed and the plotting of badger setts.


    Badger Sett Detection and Mapping

    PBA Consulting is able to scan and assess for the presence of underground badger runs (voids). In the majority of situations we can advise you on past soil disturbances related to badger occupation.

    With TreeRadar GPR we can interpret radargrams and identify the unique reflective qualities of these voids and show locations of voids with a size of 300mm diameter or greater.
