Repairing damaged underground pipes these days uses trenchless methods with very minimal disruption. However, some complex repair scenarios require a hybrid approach that uses traditional excavation with trenchless sewer repair in Shoreline, WA. This combined strategy ensures access, thoroughness, precision, and durability. Some situations demand it. 

Trenchless And Traditional Repair Combinations

When access points and cleanouts are not available, professionals begin trenchless pipe repair for sections still structurally intact but blocked or cracked. In other parts, they excavate a portion of the pipe. This is often near a building connection or junction box, where trenchless access is impossible or unsafe. This approach allows a full restoration without replacing more than necessary.

Heavily corroded or collapsed lines sometimes require a segment-by-segment strategy. Here, trenchless sewer replacement restores long pipe runs under driveways or landscaped areas. Open trenching is then used in damaged areas with poor soil integrity or where old pipe materials aren’t suitable for lining or bursting.

In some cases, both methods work well when some parts need relocation or re-layouting. Traditional excavation helps prevent sources of damage such as tree roots, roads, or heavy impact.

Combining these methods reduces costs and preserves property features. It also provides a stronger foundation and resolves the actual issues.

Other Suitable Applications

For larger diameter commercial sewer mains or deep residential systems, trenchless pipe replacement works. For manholes, complex connections, or tie-ins to city mains, specialists also use traditional digging. Contractors perform targeted excavation at critical points. Then, they seamlessly integrate trenchless replacements for the rest of the line.

Sometimes, repairs also involve internal solutions like trenchless pipe lining. Epoxy resins reinforce pipes from within. If a pipe has completely collapsed or become misaligned, traditional excavation is necessary. It realigns and stabilizes the initial section before applying pipe lining effectively.

The key to this hybrid approach lies in proper assessment. A sewer professional evaluates the full scope with video inspections and analysis. This determines which parts benefit from trenchless or traditional methods.
