Guided Auger Boring

Guided Auger Boring

Pilot Tube Guided Auger Boring (PTGAB) is one of the most popular and cost-effective trenchless methods to accurately install steel casing for underground utilities, waterlines, and sanitary sewers.  This method combines the pinpoint accuracy of the pilot tube installation to control line and grade with the excavation process of horizontal auger boring.

Case Studies

GBM Case Study – 240A

The expansion of the Port Mann Bridge to a 10-lane structure, widening Highway 1, and upgrading the interchanges were made to reduce the area’s traffic congestion and improve air quality in the Vancouver area. This involved the installation of three large-diameter drainage culverts under Highway 1, which benefited the Latimer Creek and Leoran Brook Salmon Habitat Enhancement Culverts project and satisfied one of the Port Mann/Highway 1 Improvement (PMH1) goals, to protect and improve fish passage between habitats.
