Victoria trenchless sewer
Pipe Bursting in Victoria, BC
A replacement pipe is pulled through an inspected existing route while the old pipe is split or displaced.
What this service covers
Pipe bursting replaces an inspected pipe section by pulling a new pipe through the existing route while splitting or displacing the old pipe. Entry, receiving, connection, and utility-clearance excavations may be required. Because the method generally follows the existing alignment, sags, grade problems, obstructions, nearby utilities, and connection details require separate evaluation.
Why it matters: Pipe bursting may reduce continuous trenching, but access pits and localized excavation can still be required.
Common situations
- An inspected pipe is unsuitable for lining but its route may support bursting
- Replacement or approved upsizing is being evaluated
- Reducing a continuous open trench is an important constraint
- Utilities, grade, access, and connection details support further review
What a scope should address
- Utility locating, clearance, route, depth, and grade review
- Entry, receiving, connection, and obstruction excavations
- Replacement-pipe specification and pullback method
- Connections and municipal-boundary coordination
- Backfill, restoration, and verification requirements
What affects scope and cost
- Length of pipe being replaced
- Depth, soil, and access for the pits
- Pipe size and connection details
- Landscaping or hardscape restoration expectations
Common questions
How much digging does pipe bursting need?
Insertion and receiving access are generally required, and connections, utilities, obstructions, grade corrections, or public-side boundaries can add localized excavation. The number and size of pits are site-specific.
When is bursting better than lining?
It may be considered when replacement is required and the inspected route, grade, utilities, access, and connections support bursting. A sag or alignment problem may still require excavation.
