A network runs on gradient, not hope
Gravity networks forgive the least: a few centimetres of gradient error shows after the first heavy rain. So we check gradients before the trench is backfilled, not after.
CH 0+060
What we do
- Water mains: PE pipework, valves, hydrants, service connections.
- Foul sewers: gravity lines, chambers, rising mains and pumping station connections.
- Storm drainage: gullies, carrier pipes, silt traps and oil separators on yards.
- Drainage beneath pavements and around buildings.
- Connections into live networks, agreed with the network operator.
- Trench reinstatement: layered compaction and surface restoration.

We work in live surroundings
Nearly every network job is in a street, a courtyard or the premises of an operating business. That means traffic management, temporary accesses to houses, and working in sections so that a whole street does not lose water or access at once.
Before excavation we have existing services located — somebody else's cable always costs more than a day of waiting.
Have a site? Send us the drawings.
We answer invitations to tender, subcontract enquiries and technical questions within one working day.
