Employing the latest non-invasive techniques to detect position and provide depth information on pipes, cables and drainage services. Utilising conventional cable location tools such as electro-detection equipment, we also employ Ground Penetrating Radar techniques to locate plastic pipes, voids, fibre optics and other underground anomalies. The saying

Like Land Surveys they depict topography or land form but of the river bed, sea bed, lake bed and associated features - river bank & flood plain. At Invar Mapping we undertake a variety
