Trenchless Pipe Repair & Replacement
Fix underground pipes without destroying your yard, driveway, or landscaping. Advanced CIPP lining and pipe bursting technology delivers lasting repairs with minimal disruption.
Fix Pipes Without Digging Up Your Property
Traditional pipe repair means excavation — tearing up driveways, destroying landscaping, and turning your yard into a construction zone for days or weeks. Trenchless pipe repair changes everything.
Using advanced CIPP (Cured-In-Place Pipe) lining and pipe bursting technology, Lord Mechanical repairs and replaces underground pipes through small access points — no trenching required. Your driveway stays intact. Your garden remains undisturbed. Your walkways, patios, and retaining walls are preserved.
For homeowners across North Vancouver and the North Shore, where mature landscaping and hardscaping represent significant investments, trenchless repair isn't just convenient — it's the smart financial choice. When you factor in the cost of restoring a destroyed driveway, replacing mature plantings, and repairing damaged retaining walls, trenchless methods often cost 30–50% less than traditional excavation.
The resulting repair is also superior: CIPP lining creates a seamless, jointless pipe within the existing pipe that resists root intrusion, corrosion, and wear for 50+ years — often outlasting the original pipe.
Two Proven No-Dig Methods
We use two primary trenchless technologies, selecting the right one based on your pipe's condition, material, and the specific problem we're solving.
CIPP Pipe Lining
Best for: Cracked pipes, joint separation, root intrusion, minor corrosion
CIPP (Cured-In-Place Pipe) lining creates a brand-new pipe inside your existing damaged pipe. Here's how it works:
- Camera Inspection — We identify the damage location and assess suitability for lining
- Pipe Cleaning — Hydro jetting removes debris, roots, and buildup to prepare the surface
- Liner Insertion — A flexible felt or fiberglass liner saturated with epoxy resin is inserted through an existing cleanout or access point
- Inflation — The liner is inflated with air or water pressure, pressing it firmly against the pipe walls
- Curing — Heat, steam, or UV light hardens the resin, creating a rigid, seamless pipe within the old pipe
- Final Inspection — A post-cure camera inspection verifies the liner is properly formed and the pipe flows correctly
Result: A smooth, jointless, root-proof pipe with a 50+ year expected lifespan. No excavation. Typically completed in a single day.
Pipe Bursting
Best for: Severely damaged pipes, pipes needing upsizing, collapsed sections
Pipe bursting replaces the entire existing pipe with a new one, using the old pipe's path. Here's how it works:
- Access Points — Two small pits are dug at either end of the pipe run (no trenching along the length)
- Cable Threading — A high-strength cable is threaded through the existing pipe
- Bursting Head — A cone-shaped bursting head is attached to the cable, followed by the new HDPE replacement pipe
- Pull-Through — Hydraulic pulling equipment draws the bursting head through the old pipe, fracturing it outward while simultaneously pulling the new pipe into position
- Connection — The new pipe is connected at both ends to the existing infrastructure
- Verification — Camera inspection and flow testing confirm proper installation
Result: A completely new HDPE pipe with a 50+ year lifespan, often in a larger diameter than the original. Completed in 1–2 days.
Trenchless vs. Traditional: The Comparison
Trenchless Repair
- Minimal property disruption — no trenching
- Completed in 1–2 days (vs. 3–7+ days)
- No landscaping, driveway, or patio destruction
- Seamless, jointless pipe resists root intrusion
- 50+ year expected lifespan
- Often 30–50% less total project cost
- Environmentally friendly — less waste & emissions
Traditional Excavation
- Extensive trenching across your property
- Takes 3–7+ days to complete
- Destroys landscaping, driveways & walkways
- Multiple joints create root entry points
- Expensive restoration costs add up
- Higher total cost when restoration included
- Heavy equipment, noise, and disruption
Note: Traditional excavation is still the right choice in some situations, such as when pipes are completely collapsed or severely misaligned. We always recommend the most appropriate method for your specific situation.
Perfect Situations for No-Dig Repair
Under Driveways
Pipes running beneath concrete or asphalt driveways can be repaired without breaking up the surface. Avoid the $5,000–$15,000 cost of driveway replacement.
Mature Landscaping
Protect valuable trees, gardens, and landscaping that took years to establish. Trenchless repair preserves your outdoor investment entirely.
Near Structures
Pipes running close to foundations, retaining walls, or other structures can be repaired without risking structural damage from excavation.
Deep Pipes
Pipes buried deep underground are extremely expensive to reach with traditional excavation. Trenchless methods work at any depth, making them far more cost-effective for deep repairs.
Municipal Sidewalks
Pipes that cross under municipal sidewalks or easements can be repaired without the permits, costs, and delays of breaking and restoring public infrastructure.
Quick Turnaround
Need a fast repair with minimal downtime? Most trenchless repairs are completed in a single day, compared to 3–7+ days for traditional excavation projects.
Trenchless Repair FAQ
Trenchless pipe repair is a method of fixing or replacing underground pipes without digging up your yard, driveway, or landscaping. Using advanced technology, a new pipe is created inside the existing damaged pipe (pipe lining/CIPP) or the old pipe is replaced by pulling a new one through the same path while breaking apart the old pipe (pipe bursting). Only small access points are needed rather than extensive trenching.
CIPP (Cured-In-Place Pipe) lining involves inserting a flexible liner saturated with epoxy resin into the damaged pipe through an existing access point. The liner is inflated against the pipe walls using air or water pressure, then cured with heat or UV light until the resin hardens. The result is a smooth, jointless new pipe inside the old one with a lifespan of 50+ years. Learn more about our drainage repair methods.
In many cases, yes. While the materials and technology for trenchless repair may cost more per linear foot, you save significantly on excavation, backfill, and restoration costs. There's no need to replace landscaping, driveways, walkways, or patios that would be destroyed during traditional excavation. When you factor in total project cost including restoration, trenchless repair is often 30–50% less expensive. Contact us for a detailed estimate.
CIPP pipe lining creates a seamless, jointless pipe within the existing pipe that is expected to last 50+ years. The epoxy resin liner is resistant to root intrusion, corrosion, and chemical degradation. Pipe bursting replaces the old pipe with new HDPE pipe, which also has a 50+ year expected lifespan. Both methods often outlast the original pipe. Regular maintenance helps ensure maximum longevity.
Not always. Trenchless repair works best for pipes that are cracked, have joint separation, minor root intrusion, or moderate deterioration. Pipes that are completely collapsed, severely misaligned, or have back-bellied (significant sags) may require traditional excavation for at least part of the repair. Our camera inspection determines whether trenchless methods are suitable for your specific situation.
