Underground Utilities Construction

Water, sewer, storm and franchise utilities — installed, repaired and maintained, from a residential service line to municipal mains.

Everything that goes in the ground

Underground utility work is unforgiving. It is buried before anyone can inspect it properly, and the cost of getting it wrong is measured in excavating the whole run again. We install water mains and services, sanitary sewer including gravity and force main, storm drain systems, and franchise utility conduit and duct bank for power, gas and communications.

The crews doing it are ours, the excavators and trench boxes are ours, and the people setting grade have done it before. That matters more on utilities than on almost anything else we do.

Municipal systems

We work on public water and sewer systems where the specification, the testing and the documentation are as much of the job as the pipe. Pressure testing, disinfection, video inspection, as-builts — done properly, submitted on time.

Repair and replacement

Not every utility job is new construction. A large share of our work is finding and fixing what is already there: broken water services, failed sewer laterals, collapsed storm lines, and utilities that have to be relocated because something is being built on top of them. This is the work that tends to be urgent, and we keep capacity for it.

Trenching and safety

Trench work is the most dangerous thing on most job sites. We shore, bench or box every excavation that needs it, without exception and without being asked. If a job cannot be done safely at the price someone wants, we say so.

Common questions

Questions we get asked

Do you work on municipal water and sewer systems?

Yes. Public system work including mains, services, manholes, lift stations, testing, disinfection and as-built documentation is a regular part of our workload.

Can you fix a broken water or sewer line at a house?

Yes. Residential service line repair and replacement is normal work for us, including locating the failure, excavating, repairing and restoring the surface.

How deep can you trench?

Depth is rarely the limit — ground conditions, groundwater and what else is buried nearby usually decide the method. We shore, bench or box as conditions require.

Do you locate existing utilities before you dig?

Always. Public locates go in before mobilisation and we pothole to confirm anything critical. Hitting an unmarked line is a real risk on older sites and it is worth the extra day to avoid it.

Do you restore the surface afterwards?

Yes. Backfill, compaction and surface restoration — gravel, asphalt patch, concrete or landscaping — are part of the scope unless you tell us otherwise.
