B&W Tunnelling Ltd

Since being founded in 1985, B&W has established itself across the UK and Ireland as a leading specialist trenchless & shaft contractor.

In the early years B&W’s reputation was gained from our vast experience of using traditional hand excavation techniques, constructing tunnels from 900mm to 2100mm diameter. In 1999 B&W invested in mechanised equipment and by 2002 owned one of the largest fleets of mechanised pipejacking equipment in the UK.

Working on the DCWW scheme in St Brides in 2002 B&W achieved a World Record for a 1500 TBM, pipejacking 55m of pipe in a 12-hour shift.

B&W continue to invest in new equipment, recently adding Microtunnelling to their arsenal. We can offer our clients a wide range of trenchless techniques to suit their needs and the ground conditions.

B&W Tunnelling are a highly motivated technical company continually updating their portfolio of tunnelling techniques. With a dedication to customer service we build long term relationships with clients and help identify solutions to their particular needs.

Capabilities include: TBMs, EPB TBMs & Microtunnelling; thrust boring, rock boring & guided auger boring; shaft sinking; timber & steel headings; grouting; in house fabrication for bespoke solutions; specialist plant hire.
