What is Pipe Bursting?
Pipe bursting is an advanced trenchless pipe replacement technology that demolishes old, damaged pipes and immediately replaces them with new ones—all without traditional excavation. A hydraulic bursting head slightly larger than the existing pipe diameter fractures the old pipe into fragments that get displaced into surrounding soil. Simultaneously, new HDPE, PVC, or ductile iron pipe is pulled into the newly created space behind the bursting head.
Water Pro specializes in pipe bursting for sewer lines, water lines, storm drains, and industrial pipes throughout the Greater Toronto Area. This revolutionary technology eliminates the need for yard excavation, preserves mature landscaping and expensive hardscaping, reduces project timelines dramatically, and costs 40-60% less than traditional dig-and-replace methods. Whether you're facing collapsed orangeburg sewer lines in a heritage home, corroded cast iron water mains in an older neighborhood, or damaged concrete pipes requiring complete replacement, pipe bursting delivers permanent, trenchless solutions.

How Pipe Bursting Works: Technical Breakdown
Understanding the pipe bursting process reveals why this technology delivers superior pipe replacement with minimal property disruption and maximum structural integrity.
Step 1: Camera Inspection and Assessment
Every pipe bursting project begins with comprehensive video camera inspection. High-definition cameras inserted through existing access points document damage type, location, pipe material, diameter, and structural condition. The inspection reveals collapsed sections, severe cracks, root intrusion severity, misalignment angles, and any obstacles that might complicate the bursting process.
This critical assessment determines optimal bursting head selection, new pipe diameter, equipment requirements, and access pit locations. Video documentation becomes permanent proof of damage for insurance claims or property value documentation. Professional inspection takes 30-60 minutes and costs $299-$499, but this investment prevents costly complications and ensures first-time success. Our experts discuss findings with you, recommend the most appropriate solution, and provide detailed estimates based on actual pipe conditions rather than guesswork.
Step 2: Access Pit Excavation and Positioning
Two excavation pits are created: one at the termination point of the pipe being replaced (typically at the main sewer connection or water line entry) and one at the starting point. Each pit measures approximately 4x6 feet and 4-6 feet deep—dramatically smaller than the continuous trenches traditional excavation requires. The pits provide space for the hydraulic winch that will pull the bursting head and new pipe through the existing line.
Pit placement is calculated based on pipe routing, soil conditions, and obstacle avoidance. We mark utility lines carefully to prevent strikes on electrical, gas, water, or communications infrastructure. Modern locating equipment identifies all underground utilities before any digging begins. Proper pit positioning ensures efficient equipment operation and optimal bursting head travel angle through the pipe.
Step 3: Bursting Head Insertion and Pipe Connection
The specialized bursting head—typically 5-10% larger in diameter than the pipe being replaced—is inserted into the original pipe at the termination pit. This oversized head is the key to the pipe bursting technology: as it travels through the pipe, its diameter forces the old pipe walls outward and fractures them. New HDPE, PVC, or ductile iron pipe is connected to the rear of the bursting head with a swivel joint.
The new pipe follows immediately behind the bursting head, occupying the void created as the old pipe fractures and disperses. This simultaneous replacement eliminates the need for intermediate handling and ensures continuous pipe coverage with no service interruption once installation completes. The pull cable attached to the bursting head runs to the hydraulic winch located at the starting pit, where operators control the entire replacement process with precision.
For simultaneous pipe upsizing, a larger bursting head is selected (e.g., 6-inch for replacing 4-inch pipe). The new larger pipe then occupies the expanded void, increasing flow capacity while replacing damaged infrastructure. This capability is valuable for aging systems experiencing capacity constraints due to partial blockages or corroded interiors.
Step 4: Hydraulic Winch Operation and Bursting
The hydraulic winch at the starting pit pulls the bursting head through the old pipe at carefully controlled speed (typically 30-50 feet per hour). Pressure and speed are continuously monitored through instrumentation that detects soil resistance, pipe material variations, and any obstacles. Operators adjust parameters in real-time to optimize bursting efficiency while protecting surrounding utilities and property.
As the bursting head advances, it fractures the old pipe into fragments that get displaced radially into surrounding soil. This displacement method works because soil provides adequate void space and lateral support for the fragmented pipe pieces. The soil essentially "absorbs" the displaced pipe material as the new pipe immediately fills the void. Bursting typically progresses at speeds allowing completion of 200-400 feet of replacement per day depending on pipe diameter and soil conditions.
The entire operation is controlled from the winch station with visual monitoring and instrumentation feedback. Our technicians track pressure, cable tension, and progress continuously to ensure smooth operation. Unlike excavation that's vulnerable to weather and soil variability, pipe bursting operates consistently regardless of ground conditions once the bursting head engages the original pipe.
Step 5: Final Connections and System Testing
Once the bursting head reaches the starting pit and the entire new pipe length is in place, the bursting head and cables are disconnected and removed. The new pipe now occupies the space previously held by the old pipe. Final connections are made at both access pits, restoring water and sewer service continuity. For sewer systems, cleanout connections are installed at appropriate intervals per code requirements.
Comprehensive testing follows: hydrostatic pressure testing for water lines verifies structural integrity and absence of leaks, while smoke testing or video inspection on sewer lines documents proper joint sealing and confirms no external root or water infiltration. The new pipe must meet all municipal codes and pass inspector certification before service resumes. Most projects are operational within 24-48 hours from burst completion.
Our 90-day satisfaction guarantee covers any issues that emerge during initial service period. Long-term manufacturer warranties on new pipe materials (typically 25-50+ years) protect your investment for decades. You receive documentation of all work completed, test results, new pipe specifications, and warranty information for your permanent records and future reference.
Technical Specifications: Pipe bursting equipment operates within soil bearing capacity limits, typically displacing 100-150 pounds per linear foot of fractured pipe radially into surrounding soil. HDPE new pipe is NSF-61 certified for potable water and rated for 25+ year service life, while ductile iron sewer pipe is certified for corrosive gas and root intrusion resistance per ANSI standards.
Bursting head pressure is carefully controlled (typically 50-200 tons depending on pipe size and soil) to fracture old pipe without over-stressing surrounding utilities or creating ground heave. Modern equipment includes real-time pressure monitoring, load sensors, and automated safety shutdowns that prevent equipment overload or unsafe conditions.
Pipe Bursting for Toronto Properties
Pipe bursting excels on heritage homes, established neighborhoods, and properties where landscape preservation is essential. Common Toronto applications showcase why this technology is becoming the preferred replacement method.
Heritage Homes and Historic Districts
Toronto's heritage properties (Casa Loma area, The Annex, Rosedale, historic Yorkville) face aging infrastructure replacement without tools to preserve character. Pipe bursting solves the heritage dilemma: replace failing orangeburg sewer lines or cast iron water mains while keeping century-old landscaping, historic gardens, and original hardscaping intact. Traditional excavation would destroy irreplaceable property features that define heritage character.
Many heritage homeowners choose pipe bursting specifically to upgrade aging water and sewer lines while preserving mature trees, established gardens, and heritage stonework. The technology respects property history while delivering modern, durable infrastructure designed to serve for another 50+ years.
Mature Properties with Established Landscaping
Properties featuring mature oak, maple, and elm trees, established perennial gardens, or expensive hardscaping (brick patios, stone driveways, decorative walkways) benefit dramatically from pipe bursting. Removing and replacing mature trees costs thousands of dollars and decades to recover. Preserving established landscaping while replacing pipes underneath preserves property value and visual appeal.
Cost analysis typically favors pipe bursting dramatically on these properties: even if per-foot bursting costs slightly exceed traditional replacement costs, the savings in tree replacement ($3,000-$8,000 per mature tree) and hardscape restoration ($5,000-$15,000+) make pipe bursting economically compelling in addition to the quality-of-life benefits.
Collapsed Orangeburg and Clay Pipes
Pre-1960s Toronto homes frequently feature orangeburg (asphalt-impregnated kraft fiber) or clay sewer lines that are deteriorating or partially collapsed. These materials are no longer manufactured and cannot be successfully repaired with internal liners. Pipe bursting replaces these problematic materials completely with modern ductile iron or HDPE that will serve for 50+ years without further issues.
Many homes with orangeburg failures experience recurring sewer backups, slow drainage, or catastrophic collapses. Pipe bursting eliminates these problems permanently by replacing the entire line with superior modern materials engineered for durability and resistance to root intrusion, corrosion, and structural failure.
Severely Misaligned or Undersized Pipes
Properties with severely misaligned sewer lines (pipes that have shifted, settled, or been crushed by soil pressure) often need complete replacement rather than repair. Similarly, older homes with insufficient pipe capacity for modern water usage benefit from simultaneous upsizing during replacement. Pipe bursting accomplishes both: it replaces severely damaged pipes and can increase diameter simultaneously.
A 4-inch sewer line that's misaligned and inadequate can be replaced with a properly aligned 6-inch line in single operation, solving both the damage problem and capacity constraints permanently. This capability is unique to pipe bursting technology.

Pipe Bursting FAQs
Common questions about trenchless pipe bursting technology, replacement process, and no-dig sewer solutions.
10 Questions About Pipe Bursting
What is pipe bursting technology? ▼
Pipe bursting is a trenchless technology that replaces severely damaged sewer and water lines by fracturing the old pipe with a hydraulic bursting head while simultaneously pulling new pipe into place. Only two small access pits are required instead of continuous excavation trenches, eliminating property disruption while delivering complete pipe replacement for 40-60% less cost than traditional digging.
When should I choose pipe bursting vs pipe lining? ▼
Choose pipe lining for minor to moderate damage where the existing pipe maintains structural integrity. Choose pipe bursting for collapsed sections, severe misalignment, multiple failure points, or when you need to upsize pipes. Pipe bursting is the solution for heavily deteriorated orangeburg, clay, or extensively damaged concrete pipes that cannot support internal liners. Our camera inspection determines the best method for your specific situation.
How much excavation is required for pipe bursting? ▼
Only two excavation pits measuring approximately 4x6 feet are required—one at the pipe termination point and one at the starting point. Traditional excavation digs up entire pipe runs, often creating 100+ feet of continuous trenches. Total soil disruption for pipe bursting is typically 8-12 cubic yards versus 100-200+ cubic yards for traditional excavation, preserving 90%+ of your property.
What pipe materials can be burst and replaced? ▼
Pipe bursting works on clay, concrete, cast iron, orangeburg, and certain plastic pipes from 2 inches to 36 inches in diameter. Equipment selection depends on pipe material and diameter. The technology can simultaneously upsize—replacing a 4-inch line with a new 6-inch capacity in single operation. We assess your specific pipe material through camera inspection before recommending bursting parameters and new pipe specifications.
How long does pipe bursting take? ▼
Most pipe bursting projects complete in 1-3 days from initial assessment to final inspection and system testing. Traditional excavation requires 1-2 weeks of digging plus additional restoration time. Our efficient process minimizes disruption to your daily routine while ensuring proper equipment setup, bursting operations, final connections, and comprehensive testing that guarantees the new pipe meets all municipal codes.
Can pipe bursting replace both sewer and water lines? ▼
Yes! Pipe bursting effectively replaces sewer lines, water lines, and storm drains. For water lines, we use NSF-61 certified drinking water pipe materials. For sewer applications, we use ductile iron or HDPE rated for corrosive gas and root intrusion resistance. Material selection depends on application and municipal code requirements. We assess your specific needs and recommend appropriate materials that comply with Toronto plumbing codes.
What warranty comes with pipe bursting? ▼
All pipe bursting replacements include our 90-day satisfaction guarantee plus manufacturer warranties on new pipe materials (typically 25-50+ years depending on material). The new pipes are NSF-certified or code-approved, designed for decades of reliable service. If any issues arise within the warranty period, we return at no additional cost. Your investment is protected with one of the strongest guarantees in the industry.
Will pipe bursting damage my property? ▼
Pipe bursting requires only two small excavation pits at pipe access points, typically at the sewer main connection or water line entry. The surrounding soil provides structural support as the bursting head fractures the old pipe and the new pipe occupies the void. Your landscaping, driveway, patio, and hardscaping remain completely intact. This is the primary advantage over traditional excavation that destroys hundreds of feet of yard and requires weeks of restoration work.
How much does pipe bursting cost? ▼
Pipe bursting typically costs $8,000-$15,000+ depending on pipe length, diameter, and material. When factoring in yard restoration, landscaping repair, permits, and traffic control, pipe bursting saves 40-60% compared to traditional excavation. A typical $12,000 pipe bursting project often costs $18,000-$25,000 via excavation. Call (647) 554-4356 for detailed cost comparison specific to your project.
Is pipe bursting ideal for heritage homes? ▼
Absolutely! Pipe bursting is ideal for heritage homes because it replaces aging orangeburg and clay sewer lines while preserving century-old landscaping, historic gardens, and original hardscaping. Toronto heritage properties often have excellent infrastructure location but aging pipes requiring replacement. Pipe bursting solves this perfectly: upgrade water and sewer systems while maintaining heritage character. Many heritage homeowners choose pipe bursting specifically to preserve mature trees and established gardens.
