Pilot Auger Boring

Pilot auger boring or sand boring uses a pilot steering head. The Steering head in then tracked using a right angle theodolite in the boring shaft viewing the LED lights in the head for line & level through hollow tube rods. This is then steered as necessary as the rods are inserted.

The steering head and pilot rods compress and displace the soil. This method is used in running sand with accuracy of +/- 20mm.
