Trenching & Excavation Works

Trench excavations are carried out principally to allow installation or repair of public utilities, drains and sewers to serve populated areas. Our services include trenching, excavation and shoring support in accordance with design and contract specifications.

Shaft Excavation

Shafts are the doorways to the underground tunnel, serving as the location at which all material enters and exits. They vary in size and depth, and their design and construction are key to the successful completion of any tunnelling project. Shafts are quite often larger, deeper, more complex and, in some cases, more expensive than the cost of the actual tunnel itself.
