What disqualifies a pipe from trenchless

Not every failed line is a candidate. The camera scope is what settles it, and it is the cheapest part of the decision.

  • The pipe has fully collapsed, so there is nothing left to line or burst through
  • There is a severe belly, a sagging section holding standing water
  • Offset joints wider than about half an inch
  • The run has been previously repaired with a section the bursting head cannot pass
  • The line crosses under a structure with no room for an access pit at either end
  • Ground conditions at the pit locations will not hold an open face safely

What trenchless means in Vancouver

Old school water line replacement meant digging an open trench from the city main at the curb all the way to the house. On a Vancouver lot that is typically 25 to 65 feet of trench across driveway, lawn and garden, sometimes straight through mature root systems and irrigation. You pay for the excavation before any pipe goes in, then you pay again to put the landscaping and the driveway back.

Trenchless skips most of that. We dig two small access pits, one at the city stop valve near the property line and one at the house entry. Then we pull a new HDPE or copper line along the path of the old one with a hydraulic bursting head that fragments the existing pipe outward while drawing the new pipe in behind it. Total open ground is roughly six feet of pit at each end. Everything between them stays where it is.

The same technique covers sewer laterals. CIPP, cured in place pipe, pushes an epoxy impregnated felt sleeve into the existing pipe, inflates it and cures it into a structural pipe inside a pipe. No digging at all between the cleanouts. It is the right call when the host pipe is structurally sound but cracked, open at the joints, or root invaded.

Where trenchless wins hardest. Mature landscaping, a finished concrete driveway, a City of Vancouver street cut permit, or anything involving the city sidewalk. Open trench on a typical lot means breaking twenty to thirty feet of driveway. Thirty year old hydrangeas, established lawn, irrigation lines and decorative pavers all stay in place with two pits. The harder your yard is to put back, the bigger the trenchless advantage.

Lead service lines. Many pre-1950 Vancouver homes still have a lead service line running from the city main to the house, and lead in drinking water is a documented health risk, particularly for children. The City of Vancouver runs a lead service line replacement programme with cost sharing for eligible properties, and the split is straightforward. The City handles the public side, from the curb stop back to the main. The private side, curb stop to the house, is the owner’s. Trenchless on the private side keeps the front yard, walkways and driveway intact while modern Type-K copper or HDPE goes in. We coordinate with the City inspection schedule so private side and public side work land back to back. Most of ours have been in Hastings-Sunrise, Strathcona, Grandview-Woodland and Mount Pleasant, the East Van neighbourhoods with the highest concentration of pre-1950 service lines.

Trenchless services we offer

Pipe bursting for the water service line

Replace a failed copper, galvanized or lead water service with new HDPE or Type-K copper. The hydraulic bursting head fractures the old pipe outward and pulls the new pipe in behind it. Two access pits, no driveway demolition. Quoted by length and ground conditions.

CIPP sewer lining

Cured in place pipe for sewer lateral repair. An epoxy impregnated felt sleeve is pushed through the existing pipe, inflated, and cured into a structural pipe in pipe. No digging. Best on structurally sound pipe with cracks, root intrusion at the joints, or scale. We use Hammerhead and Insituform style liner systems, rated past 50 years of service life.

Pull in place liner for a spot repair

For a single failed section in an otherwise good lateral. A short epoxy sleeve is pulled into the damaged section only and cured there. Cheaper than lining the whole run when the camera shows one defect and nothing else.

Lead service line replacement

Pre-1950 Vancouver homes with a lead service line. Private side trenchless replacement coordinated with City of Vancouver public side work. Eligible properties qualify for the City cost sharing programme and you cover the homeowner portion.

Galvanized service line replacement

Pre-1960 Vancouver galvanized supply lines corrode internally, some down past a quarter of their original diameter. We burst them out to HDPE or copper and restore full pressure through the house. Ask about a whole house repipe as well if the interior galvanized is the same vintage.

Trenchless replacement FAQ, Vancouver

Two small access pits, roughly four feet square and four feet deep, at each end of the line. Everything in between stays intact. The pits are restored as part of the project. An open trench equivalent would dig the entire run.

Usually, once restoration is in the number. The trenchless project on its own can be similar or slightly higher than the excavation alone, but an open trench also brings a concrete driveway re-pour, lawn restoration, irrigation repair and a city sidewalk permit. Net saving is typically 30 to 60 percent.

No. Collapsed pipe, a severe belly, and offset joints wider than about half an inch all need an open trench. We scope on camera first to confirm trenchless will work. If it will not, we say so up front and quote the open trench instead.

HDPE water service carries a 50 year manufacturer warranty on the pipe and a 10 year workmanship warranty on the Mamba install. Type-K copper runs about 50 years of typical service life. CIPP liner carries a 50 year manufacturer warranty on the cured liner. All the documentation is emailed at project completion.

Yes. A plumbing permit from City of Vancouver, or from Burnaby, Richmond, New Westminster, Surrey or Delta depending on where you are. We pull the permit, coordinate the inspection and produce the stamped certificate. It is in the quote.

Yes. Pre-1950 Vancouver homes often have one. The City of Vancouver runs a lead replacement programme with cost sharing for eligible properties. We handle the homeowner side trenchless replacement and coordinate with the City for the public side. You pay the homeowner portion.

Trenchless usually avoids the sidewalk entirely, because we set the pit just inside the property line. Where an open trench across the sidewalk is unavoidable, we pull the sidewalk permit, arrange traffic control and have the concrete patched by the City’s approved contractor.

Pre-1950 Vancouver homes are the highest risk. Lead is soft grey, slightly bendable, and a magnet will not stick to it. Galvanized is silver grey, hard, and a magnet does stick. Copper is pink orange. If you are unsure we test the visible portion in the basement and confirm the buried portion against City of Vancouver service records.

Not in any way you will notice. The cured liner takes roughly a quarter inch off the inside diameter of a four inch lateral, and residential flow rates do not care. What you gain is a smooth wall with sealed joints and no entry points for roots.

HDPE is flexible, tolerant of freezing, does not corrode and costs less. Type-K copper has a hundred year track record and the resale familiarity that comes with it. We quote both with the trade offs written down so you can pick.
