Tunnelling

AH Group Is focused on tunnelling and holds it at the heart of our business. Contact Us

We have grown rapidly within the industry over the last few years, laying strong foundations for relationships with both staff and clients. Our vision is to build upon these existing relationships as well as forging new partnerships in order to further enhance and expand our interests in this area. 

We approach every project individually.

We work collaboratively with our clients assessing all aspects from project inception to completion in order to determine the best solutions and most appropriate individuals to the client and project requirements. 

We provide all required personnel for all stages of tunnelling works from TBM assembly, and the tunnelling works through to TBM disassembly and tunnel snagging works.
