Radio detection
Radio detection is an effective method for accurately determining the location of cables and pipes. This involves placing a unique signal on a metallic cable or pipe, which can then be tracked from ground level using a receiver. Because the signal is linked specifically to a single object, this technique is highly reliable.

Precise detection of metallic cables and pipes
Radio detection is an effective technique in which a unique signal is transmitted along a metallic cable or pipe. This signal can be tracked at the surface using a receiver, allowing the location of the cable or pipe to be determined with precision. Because the signal is uniquely attached to a specific cable or pipeline, radio detection is highly reliable. When the cable or pipeline is traced, its exact position is digitally recorded using GPS, 06-GPS, or a tachymeter. In this way, cables and pipes can be accurately mapped.
crosstalk
For cable clusters
In situations involving complex cable clusters, “crosstalk” can occur. This means that the signal from one cable jumps to an adjacent cable, which can affect the accuracy of the measurement. To correct for this crosstalk, we often combine radio detection measurements with other techniques, such as ground-penetrating radar or test trenches. This combined approach ensures reliable and accurate results, even in complex underground infrastructures.
detection of non-
metal cables and pipes
Non-metallic cables and pipes, such as fiber optics, PVC, concrete, sewer pipes, and drainage pipes, cannot be detected using radio detection. In such cases, we use alternative methods such as ground-penetrating radar or manual digging. In addition, we can insert a probe into the pipe, to which we apply the same radio detection technique used for metal pipes. This method is frequently used to locate directed drilling of fiber-optic cables or to map municipal sewer pressure pipe networks.
Innovation
applications
Within TerraCarta, we are constantly working on innovative solutions. One of these innovations is a specially developed pressure vault used for detecting pipes under pressure, such as gas pipelines. This technique makes it possible to insert a tendon into the pipe without gas leakage, allowing us to perform safe and accurate measurements even in complex situations.
