We are drainage service providers for the Network rail Lot 3 South east route and deliver works for Align JV as part of the HS2 construction works until at least 2024.

Flowline’s Rail division have carried out CCTV Surveys, high pressure water jetting, line cleaning and relining / rehabilitation works at Paddington, Euston and Kings Cross Main Line Stations as well as trackside works at various other UK locations.

Aside from Network rail, we also regularly deliver a full range of drainage services on Crossrail and HS2 enabling works.

These services have included:

  • High risk entry and rescue teams
  • Float and walkthrough condition surveys
  • Reduct surveys
  • 3D modelling of local drainage assets
  • Pipe relining

Flowline are fully equipped to carry out works virtually anywhere, including locations and awkward areas with weight, height or width restrictions which are easily managed by our rubber tracked self-powered hydraulic hose reel carrying additional high pressure water jetting hose, and battery powered CCTV Survey equipment for surveying in locations without any electrical power and where use of our on board or portable generators may not be possible such as roofs and canopies, enclosed spaces and basement locations.
