Tunnelling
Services
ASG have adequate resources in manpower, machinery, plant and equipment to handle both small and large scale tunnelling projects.
The services we offer include shaft sinking, pipe jacking, segmental tunnelling, timber headings etc. In essence we can professionally undertake almost all drainage, storage and tunnelling works.
Shaft Sinking -
As one of our main areas of expertise, we carry out all types of shaft sinking, including casing, underpinning and pile shafts. We have provided our expert and professional service to many large impressive construction companies.
Pipe Jacking -
This effective technique for installing underground pipelines, ducts, culverts etc is another one of our primary services. We guarantee water-tight, flexible results every time.
Segmental Tunnelling -
This reliable and modern method for tunnelling is offered where medium to long lengths are required.
Timber Headings/Tunnelling -
Here, we use a man-made timber frame to secure a tunnel structure after the material has been excavated. This traditional technique is neglected by many firms but we retain the capability to carry this work out. This method covers mainly short distances where open cut installation is not practical and the scheme does not warrant the use of more expensive tunnelling techniques
