Both tree root radar surveys and airspade investigations enable us to locate tree roots, or lack of, within certain areas to enable planning and management decisions to be made that do not unduly harm the tree or put unnecessary restriction on the proposal. When deciding on what method of root investigations are needed, we evaluate a number of factors for the project that include the overall area to be surveyed, the reasons for the survey and what stage of planning the project is in, and the type of surfacing that is in the area.
What are the differences between Airspade investigations and Tree Root Radar Surveys?
Airspade investigations use high pressure air to physically remove the soil in the areas to be investigated to that all of the roots that are found in the area can be recorded. This process, although accurate and definitive is also time consuming and involves the excavation of patios, lawns, driveways etc.
Tree Root Radar Surveys
Tree root radars urveys use Ground Penetrating Radar to scan the ground and detect and plot the locations of tree roots within the soil. These results are plotted into a number of graphical outputs to help inform management decisions. Tree Root Radar Surveys are especially useful for scanning larger areas, that would be economically unviable to excavate using Airspade tools. They are equally useful for scanning areas where excavation would be impractical or expensive to reinstate. Such as footpaths, driveways, roads or within buildings.
What option is best for your project?
It is more efficient and cost effective in smaller areas, sites with tight access or other constraints to survey using Airspade investigations. Air spading is accurate and will allow, if required, planners and tree officers to see roots or their lack of.
Larger areas, sites where excavation is undesirable or even early stage planning where you are looking to get a general idea of the underground rooting activity are ideal sites to conduct tree root radar surveys.
