Invisible detection

A self-contained, ground penetrating radar system (GPR) is now available from US Radar. The system is said to be technologically-advanced and simple to use, with a touch screen operating system and a variety of antenna frequency options. The Seeker GPR can be used in numerous surface materials such as soil, clay, concrete and brick. It integrates a complete imaging system into a single unit and can be used in application such as underground construction, road and bridge building, structural and civil engine

A self-contained, ground penetrating radar system (GPR) is now available from 2330 US Radar. The system is said to be technologically-advanced and simple to use, with a touch screen operating system and a variety of antenna frequency options. The Seeker GPR can be used in numerous surface materials such as soil, clay, concrete and brick. It integrates a complete imaging system into a single unit and can be used in application such as underground construction, road and bridge building, structural and civil engineering and underground utility works.

The system transmits energy pulses and is able to display an image of the sub-surface on the operator interface. Users can set a range of parameters such as soil type or display colours using the touch screen before each survey to boost efficiency, while the system can also be set to focus on a particular depth range. Five antenna frequency options are offered, which meets a broad range of detection needs and these are said to be easily interchangeable. The highest resolution option, 2,000MHz, can detect to depths up to 457mm and see the smallest objects, such as fine wire and cracks in concrete. At a lower resolution, the 1,000MHz setting detects slightly larger objects including rebar and wire mesh in depths up to 1.07m. The versatile unit, the 500 MHz, offers a detection depth up to 4.7m and can be used

to recognise soil disturbances, and find large and small pipes and cables. The 250MHz and 100MHz options can see up to 9.14 and 30.5m, respectively, and can detect large objects such as bedrock and big pipes.

    PipeHawk has used its sophisticated ground probing radar (GPR) technology to develop the e-Spott system for the highways sector. The e-Spott package has been designed and developed in collaboration with another GPR specialist, Utsi Electronics. This new system is said to provide a fast and reliable method of testing the total thickness of bound layers to the sub-base interface or the thickness of surface concrete. This system has advantages over traditional coring methods as there is no need to cause disrup

    Fugro Aperio says it is improving the quality of road and airport runway repair techniques using its sophisticated ground penetrating radar (GPR) technology. The firm is now able to offer a combination of real time kinematic (RTK) GPS with multi channel radar systems due to partnerships with Yotta in the UK, and Pavement Management Services in Australia and the Middle East. This sophisticated package enables pre-planning of surveys, quicker execution and better positioning for more precise mapping of defect
  • Simex: Road Maintenance

    In the world of road maintenance and paving, as well as construction, the issue of recovering material deriving from demolition and scarification is becoming increasingly urgent, with the dual objective of combining environmental protection with economic savings. Those who work in the sector are well aware of the huge costs of transporting and disposing of asphalt and material from demolition, as well as the costs for the purchase and transport of new raw materials to the site. Now, as never before, the sector features its own circular economy, particularly in regards to bituminous conglomerates: road paving can be recycled several times, in full compliance with the regulations in force.
