Trenchless Sewer Repair in Tigard, Oregon
Traditional sewer line repair means digging a trench across your entire yard. Trenchless repair fixes the same problem — root intrusion, cracks, collapsed sections, bellied pipe — with two small access holes and no destroyed landscaping. True Flow Plumbing performs trenchless sewer repair throughout Tigard.
Trenchless Sewer Repair in Tigard
Tigard's 1970s and 1980s sewer laterals are primarily ABS plastic — a material that can belly, crack at joints, or separate over 40–50 years of soil movement. Trenchless spot-lining is effective for isolated sections with belly or joint separation issues. For longer sections with multiple problems, pipe bursting replaces the entire lateral without the excavation that would disrupt Tigard's established neighborhoods.
🔵 Pipe Lining (CIPP)
A resin-saturated felt liner is inserted into the existing pipe and inflated against the pipe walls, then cured in place. The result is a seamless new pipe inside the old one — no joints for roots to re-enter. Rated for 50 years.
💥 Pipe Bursting
A bursting head is pulled through the old pipe, fracturing it outward while simultaneously pulling a new HDPE pipe into place. Effective for collapsed or severely deteriorated sections where lining isn't possible.
🎥 Pre-Repair Camera Scope
Every trenchless job starts with a sewer camera inspection — we confirm the pipe condition, measure dimensions, and identify the exact section to be repaired before any work starts.
🌿 Minimal Yard Disruption
Two access pits — one at each end of the repair section — are all we need. Your lawn, garden, concrete, and hardscaping between those points stay intact.
📋 Post-Repair Inspection
After lining or bursting, we run the camera again to confirm the repair is complete and the pipe is flowing correctly before we close the access pits.
🏠 Spot Repairs
Not every problem requires full-line replacement. Isolated sections with a single belly, crack, or joint failure can sometimes be spot-lined rather than replaced end to end.
When Trenchless Is the Right Choice in Tigard
- Sewer line runs under a driveway, patio, deck, or concrete surface
- Established trees, gardens, or landscaping would be destroyed by open excavation
- Sewer scope shows root intrusion, cracks, or minor bellying — but the pipe is still structurally intact enough to line
- The sewer line is 4–6 inches in diameter (most residential laterals qualify)
- Property access makes bringing excavation equipment difficult
- You want a 50-year solution rather than another temporary clearing

Frequently Asked Questions
What is trenchless sewer repair and how does it work in Tigard?
Trenchless sewer repair rehabilitates your sewer lateral without excavating the entire line. Pipe lining (CIPP) inserts a resin-saturated liner into the existing pipe and cures it in place — creating a new pipe inside the old one. Pipe bursting pulls a new pipe through the old one while simultaneously fracturing the original. Both methods require access pits at each end of the repair section, but leave the yard between them intact.
How much does trenchless sewer repair cost in Tigard compared to traditional excavation?
Trenchless repair typically costs 20–40% more than open excavation for the pipe work alone — but that comparison ignores the cost of restoring everything excavation destroys: concrete, landscaping, pavement, fences, and irrigation systems. When you factor in full restoration costs, trenchless is frequently less expensive overall, especially on properties with established landscaping and hardscaping.
How long does a trenchless sewer repair last in Tigard?
CIPP (cured-in-place pipe) liners are rated for 50 years and are resistant to root intrusion because the liner has no joints for roots to enter. Pipe bursting installs a new HDPE pipe with a similar lifespan. Both methods are significantly more durable than the original clay or cast iron pipe they replace.
