Service Overview
Trenchless sewer repair,
explained.
Trenchless sewer repair is a family of methods that rehabilitate or replace underground sewer pipes without a continuous excavation trench. There are three primary approaches.
Method 01
Pipe bursting
A bursting head is pulled through the existing pipe, fracturing it outward into the surrounding soil. A new HDPE pipe is pulled through the same path in the same pass.
- Suited to severely deteriorated or root-invaded lines
- Can upsize the pipe diameter in some cases
- Requires small entry and exit pits
- Not suitable for every pipe material
Method 02
Cured-in-place pipe (CIPP) lining
A flexible liner saturated with resin is inserted into the existing pipe, inflated against the pipe walls, and cured in place. The result is a new structural lining inside the old pipe.
- Preserves the existing pipe alignment
- Creates a smooth, corrosion-resistant interior
- Typically requires only small access points
- Best for pipes that still have structural integrity
Method 03
No-dig sewer replacement
When lining isn't viable and bursting isn't appropriate, a new pipe can sometimes be installed using horizontal directional drilling or other trenchless techniques — reaching the line from a limited number of access points.
- Useful when pipe material or condition rules out lining
- Can avoid disturbing driveways and mature landscaping
- Site conditions determine whether it applies
