Service description

Incorrectly recorded or missing pipes, ducts, and cables in registers can be detected easily by using the soil radar operated with the most advanced technology currently available. With this solution, the track of any water pipe (metallic, PVC, or concrete or any other material) can be easily determined, and it can also be used for the mapping of public utilities before starting major construction works.

Principles of operation

The soil radar emits electromagnetic pulses, which enter the soil (medium) and – due to their dielectric nature – they are reflected to the receiving antenna.

Operation in the practice

The soil radar consists of a transmitter and a receiver antenna as well as a central control unit. This unit controls the signal emission and communicates with the PC controlling the measurement process. The transmitter moves on the surface of the ground and emits short electromagnetic waves to the ground up to the depth of 6 metres. The electromagnetic signals are reflected differently from the different soil structures and from the subsurface public utility elements to the receiver unit. The reflected signals are recorded by the receiver antenna, therefore, a time segment is obtained where the reflected signals are displayed. The reflected signals will be processed by the control unit of the radar for 2D imaging, which can also be used as the basis of the special 3D evaluation by a special PC.

Processing of the measurement data is supported – in addition to the geophysical skills – also by appropriate software applications.

Major advantages of the service

The soil radar enables the detection of underground, non-metallic materials and objects penetrating to the depth of 4-5 meters, and the survey of the soil structure, therefore, there is no need for costly and time-consuming demolishing, reconstruction, digging, or sampling works.

Key areas of application

Public utility services

It is not possible to detect non-metallic public utilities by traditional means. Public utility service providers using soil radar can obtain accurate information on the location of their network and other underground elements. In addition to the solution offered to these problems, the soil radar is able to detect cavities and other anomalies of the soil structure.

Usage of the soil radar may be important in defining new tracks, in the detection of public utilities, the track of which is unknown, or in the detection of the partner public utility networks before starting a demolishing work.

Soil radar measurement is simpler and faster than traditional solutions, and evaluation of the measurement data is also less time-consuming. In addition to that, the data we obtain about the location of the particular objects and network elements are relatively accurate, which allows the development of a ground map after combining these data with GPS coordinates.

Road network

It is the best solution for determining the thickness of the road structure layers, detecting the cavities, the starting road breaks, localising the freezing points, and identifying the position of both metallic and non-metallic public utility elements under the road.

Archaeology

As a result of a fast and efficient soil radar survey, more targeted archaeological excavations can be implemented before starting a road construction work and other large investment projects. The non-destructive test can not only detect the location of sub-soil structures but also their depth.
