Pipelines

We are a civil engineering contractor specialising in the construction, repair, and rehabilitation of large diameter pipelines and associated structures in the water and wastewater industry. 

We specialise in urban city (infill or brown field) pipeline construction, undertaking typically deep, wet, difficult jobs between existing underground and overhead services and obstructions.

We also have vast experience in green field and cross county pipeline construction.

We have completed many projects involving extensive dewatering systems, and can offer well-pointing dewatering setups for excavations in any ground conditions.

We also have expertise in setting up large diameter wastewater pipeline bypass pumping. We have an extensive range of large vacuum and submersible pumps, temporary bypass pipelines, creative bypass pumping methodologies, well-points and header pipe, and traffic management.
