Deep excavations, shafts and headings

With experience working with major contactors in the water, sewage, communications and rail industries, we have carried out major shaft and heading projects.


Working as a second or third tier contractor, CBNL has successfully completed numerous projects, with particular focus working in built up areas in and around London where specialist care is required in order to navigate past existing services.


In addition to commercial projects, CBNL has completed residential projects including connections for basement flats, repairs to existing pipe work and new builds.
