Trenchless Drain Repair & Pipe Lining Services
Our trenchless drain repair and pipe lining methods restore structural integrity without excavation, keeping your property intact. Serving homeowners, property managers, and businesses across Ontario, the Greater Toronto Area, our certified technicians use advanced CIPP lining and no-dig technology to deliver durable, code-compliant repairs with minimal downtime. Torpedo technology allows us make new tunnels underground with no massive excavation.
What Is the Torpedo Method in Trenchless Plumbing?
The torpedo method—also called pneumatic piercing—is a trenchless installation technique used for running new water service lines or utility conduits beneath existing surfaces without digging long trenches. At Anta Plumbing, our City of Toronto–licensed plumbers use compressed-air powered torpedo tools to create a narrow underground tunnel, allowing us to install pipes beneath driveways, sidewalks, patios, and landscaped areas with minimal surface disruption.

How Torpedo Technology Works
A pneumatic torpedo tool is propelled forward through the soil at up to 200 psi, forming a smooth borehole that can accommodate pipe diameters of approximately 2″ to 4″. This channel allows for the safe installation of water lines, drain pipes, or electrical conduits without disturbing hardscapes or structural foundations. Because the method avoids open excavation, it’s faster, cleaner, and ideal for locations where access is restricted or where preserving landscaping is a priority. Electricians and utility contractors also use torpedo boring to run power cables or communication lines under paved surfaces without demolition.
What Is the Pipe Bursting Method in Trenchless Pipe Replacement?
Pipe bursting is a trenchless replacement technique that allows worn, undersized, or damaged water lines and sewer laterals to be replaced without open trench excavation. At Anta Plumbing, our licensed technicians use a hydraulic or pneumatic bursting head to fracture the old pipe from within while simultaneously pulling a brand-new, durable replacement pipe into place. This method works with materials like clay, cast iron, and PVC, and is ideal for upgrading pipe capacity while preserving your landscaping, driveway, or patio.
How Pipe Bursting Works
A conical bursting tool is inserted into the existing pipeline via small access pits. As it advances, the tool applies radial force to split or shatter the old pipe, displacing fragments into the surrounding soil. Directly behind the bursting head, a new pipe—often high-density polyethylene (HDPE) or PVC—is pulled into the freshly created channel. If an upsized pipe is required, a larger expansion cone is used to increase the bore diameter before insertion.
Why Choose Pipe Bursting Over Traditional Excavation?
Minimal Surface Disruption – Avoids large-scale digging and property damage.
Cost-Effective – Lower labor, restoration, and traffic control expenses.
Faster Completion – Reduces downtime for homes and businesses.
Environmentally Friendly – Preserves vegetation and prevents excess soil displacement.
Scalable Capacity – Allows installation of larger-diameter pipes for increased flow.
This makes pipe bursting an excellent solution for long-term pipe rehabilitation, particularly when upgrading utility lines beneath established landscapes or hardscapes.
What Is the Cured-in-Place Pipe (CIPP) Lining Method?
The lining method, also called cured-in-place pipe (CIPP) or epoxy pipe lining, is a trenchless rehabilitation process that restores the structural integrity of underground sewer lines, storm drains, and water service pipes without excavation. At Anta Plumbing, our certified technicians insert a resin-saturated felt or fiberglass liner into the existing pipe. Once positioned, the liner is inflated and cured—using steam, hot water, or UV light—creating a seamless, jointless “pipe within a pipe” that meets ASTM F1216 standards.
Where the Lining Method Works Best
CIPP lining is ideal when digging is impractical, expensive, or would cause significant disruption, including:
Beneath newly paved driveways or resurfaced parking lots
Through landscaped areas with costly plantings or hardscape features
Under porches, patios, or interlocking stone walkways
In locations with electrical or gas utilities directly above or below
Beneath interior floors, finished basements, or high-value flooring
Along roadways or in busy commercial lots where closures aren’t feasible
Near irrigation or sprinkler systems that must remain intact
Why Choose Pipe Lining Over Dig-and-Replace?
No Surface Damage – Preserve landscaping, paving, and structures.
Long Service Life – CIPP liners are engineered for 50+ years of durability.
Fast Turnaround – Most residential lines are restored within one day.
Versatile Application – Works on clay, cast iron, PVC, and concrete pipes.
Improved Flow – Smooth, jointless interior resists corrosion and root intrusion.
By eliminating the need for full-scale excavation, the lining method offers a cost-effective, environmentally friendly solution for extending the life of existing pipelines.

Our Trenchless Repair Process
At Anta Plumbing, every trenchless drain repair starts with a thorough assessment so we can match the right method—torpedo boring, pipe bursting, or cured-in-place pipe (CIPP) lining—to your specific situation.
1. CCTV Inspection & Assessment
We use high-definition CCTV cameras to map your sewer line or water service from end to end. This reveals cracks, blockages, corrosion, root intrusion, or collapsed sections so we can choose the most effective repair approach.
2. Site Preparation & Utility Location
Before any work begins, we locate gas, electrical, and communication lines to ensure a safe, code-compliant repair. Access pits or launch points are prepared where necessary, keeping surface disruption to a minimum.
3. Cleaning & Debris Removal
For lining or bursting, the existing pipe is cleaned using hydro-jetting or mechanical milling to remove roots, scale, or sediment. A clean host pipe ensures proper bonding of liners or smooth installation of replacement pipes.
4. Method-Specific Repair
Torpedo Method: Pneumatic piercing tool creates a bore for new pipe or conduit installation.
Pipe Bursting: Bursting head fractures the old pipe while pulling in the new pipe in one continuous motion.
CIPP Lining: Resin-saturated liner is inverted into the pipe, inflated, and cured with steam, hot water, or UV light.
5. Final Inspection & Testing
We run a post-repair CCTV inspection to verify structural integrity, smooth flow, and leak-free joints. Pressure tests or flow tests may be performed to ensure compliance with Ontario Building Code standards.
6. Cleanup & Restoration
Our crews restore any disturbed surfaces and leave your property clean and ready to use—often within the same day for residential jobs.
