Next generation GPR Technology at National Grid Cable Avoidance Day

Prominent guests and speakers from the UK construction industry were ever present. Welcome and Introduction to the event was given by Michael Dyke, Director of UK Construction, National Grid, and Mark Fairbairn, Executive Director, Gas Distribution, National Grid. The new TT Group GPR Horizontal Directional Drilling Bore-head with durable antennas with ‘look ahead and look sideways’ capability was highlighted and on display.



The ORFEUS project, which is a European Commission funded collaborative research study, with the following three main objectives:

  • To prototype an innovative GPR-based real-time obstacle detection system for steerable bore-heads of Horizontal Directional Drilling (HDD) pipe and cable laying systems so that they can operate more safely below ground.
  • To provide a step change in the depth penetration and spatial resolution of GPR used for surveys carried out from the ground surface.
  • To increase knowledge of the electrical behaviour of the ground, by means of in-situ measurements to enhance understanding of the sub-soil electrical environment, and to provide information for scientifically based antenna design.

This brand new advancement in cable and pipe avoidance was just one of the many trenchless or minimal dig techniques on show.

During the inter-active morning and afternoon sessions, VIPs and over 200 guests visited the exhibition stands and TT-UK were able to display their range of the industry’s preferred GRUNDOMAT Soil Displacement Hammers for accurate and reliable service and mains laying and GRUNDOBURST 400G on-line gas/water pipe replacement systems. The GRUNDOBURST can pull in a variety of replacement pipe including PVC, DIP, ABS, cast iron, fusion welded HDPE and VCP jacking pipe. Pulled by a hydraulic bursting unit, the cutter head’s special roller cutting wheels split the host pipe. Six models are available for bursting 2-inch (50mm) through 54-inch (1400mm) pipes and larger.

Due to the exceptionally fine weather on the launch day, TT-UK were able to demonstrate their new City Sucker 7.5 tonne Suction Excavator which, when used in city centre environments, greatly reduces the risk of cable strike and inadvertent damage to other third party buried plant in the vicinity.
