Guided Thrust Boring
  Guided auger boring is a steered method used toinstall gravity pipes from 150mmØ to 900mmØ.Prior to pipe installation, a pilot bore is driven toline/level and all aspects of this method fullysupport the ground during installation. Ideal forboring in a wide range of materials and whereminimal settlement is critical. These systems areaccurate to +/- 25mm over a 50 metre borelength, DN150 to DN725mm Naylor DenlokVitrified Clay can be installed.
