Chris Marley Tunnelling Ltd is expert in deep drainage works. We carry out deep trench work usually for awkward sewer connections:

• New pipe runs: concrete, plastic, in box culverts then backfilled, from a few meters to many kilometers long.
• Fixing existing runs: sinking a pit to repair existing sewers then backfilling once completed. The pit is supported using steel sheet piles and hydraulic frames, which are then removed during back filling.
